Flying With a Mobility Scooter: All 6 Major US Airline Policies Compared

The short version

We built this guide because the advice online is genuinely bad. Search for mobility scooter battery rules and you will be told, over and over, that your limit is 100 or 160 watt-hours. Then you arrive at the airport with a 262 Wh scooter battery and get waved straight through — or, on a different airline, turned away for a reason no article warned you about.

Both outcomes come from the same mistake. The widely-quoted numbers govern consumer electronics. Mobility devices are covered by a separate part of the federal rules, and then each airline layers its own policy on top — and those policies differ far more than most travellers expect.

Below is every published rule from all six major US carriers, quoted directly from their own pages, with the federal regulation underneath. Where an airline does not publish an answer, we say so rather than guessing.

The master comparison

Battery rules

Notice and paperwork

Read that table once and the strategic point becomes obvious: if you fly more than one airline, plan for the strictest one. A scooter set up to satisfy Alaska — removable battery, English label showing watt-hours, under 300 Wh — will clear every other carrier on this list. The reverse is not true.

The watt-hour rule everyone gets wrong

The 100 Wh and 160 Wh figures come from the FAA's general rules for portable electronics. Mobility devices sit under 49 CFR 175.10(a)(15)–(17), which splits the rules by a question nobody thinks to ask: does the battery have to come out of the device?

If the battery must be removed — because the device design doesn't adequately protect it — the FAA states:

"Lithium ion battery size is limited to 300 watt hours (Wh). One spare battery not exceeding 300 Wh or two spare batteries not exceeding 160 Wh each may be carried in carry-on baggage."

— FAA PackSafe — Wheelchairs & Mobility Devices, updated 1 May 2024

If the battery is adequately protected and stays installed, the regulation sets no watt-hour limit at all. United is the only carrier that says this out loud:

"There is no watt-hour limit for the battery installed in the device."

— United Airlines — Wheelchairs and mobility devices

Two rules apply everywhere, without exception:

• Spare batteries are carry-on only. Never in a checked bag — and if your carry-on gets gate-checked, take the spare out and keep it with you.
• Lithium metal batteries are forbidden. These are the non-rechargeable kind. Every mainstream mobility device uses rechargeable lithium-ion, but it matters if you're buying second-hand.

How to work out your own watt-hours

If your battery shows only volts and amp-hours, Alaska publishes the arithmetic:

"Volts (V) x Amp-hours (Ah) = Watt-hours (Wh)"

— Alaska Airlines — Mobility and wheelchair assistance

So a 25.2 V, 10.4 Ah battery is 25.2 × 10.4 = 262 Wh. If the label gives milliamp-hours instead, divide by 1,000 first.

Alaska Airlines (and Hawaiian)

The strictest carrier of the six, and the most explicit. Alaska will refuse a device outright on grounds no other airline states:

"Mobility aids where the battery is fully enclosed and can't be easily removed, or the mobility aid has a battery that exceeds 300 watt-hours will not be accepted for transport."

— Alaska Airlines — Mobility and wheelchair assistance

"The battery must be easily removed and transported separately as carryon baggage in the passenger cabin. The battery terminals must be protected from short circuit. There is a single battery size limit of 300 watt-hours (Wh). If the device utilizes two batteries, each battery cannot exceed 160 Wh. A maximum of one spare battery not exceeding 300 Wh or two spares not exceeding 160 Wh each may be carried onboard."

— Alaska Airlines

The labelling requirement is the one that catches people out. Alaska requires the battery's rating to be visible, and the label to be readable:

"The battery's size in watt-hours must be displayed on the battery, or the battery should be labeled with its voltage and amp-hour (or milliamp-hour) ratings to allow for size calculation."

— Alaska Airlines

Alaska also states that the battery label "must be legible and in English," and lists "batteries labeled in language other than English" among the items it does not accept. If your scooter's battery carries a label in another language, photograph the manufacturer's specification sheet and bring it.

The device also needs a single physical means of power disconnection — a removable key, an on/off switch secured to off, a quick-disconnect joystick, or a removed battery with isolated terminals.

Alaska's per-aircraft limits — the most useful table any airline publishes

Note the E175 restriction: that aircraft "can accommodate only one (1) battery-powered mobility aid weighing over 50 lbs. per flight." If your scooter is under 50 lb, this limit doesn't apply to you — a real advantage of an ultralight device on regional routes.

Practicalities: a personal wheelchair "can be checked at the ticket counter or the gate free of charge," and is returned at the destination gate or connecting airport. Alaska asks you to arrive at least two hours before departure and provides a Mobility Aid Information Form. Accessible services: 1-800-503-0101 (dial 711 for relay).

Southwest Airlines

Nearly as strict as Alaska on batteries, and the clearest on device size.

"There is a single battery size limit of 300 watt-hours (Wh). If the device uses two batteries, each battery cannot exceed 160 Wh."

— Southwest — Battery-powered wheelchairs and mobility aids

"All lithium-ion powered mobility aids (wheelchair/scooters) must have the battery removed, and the battery must be transported separately as carryon baggage."

— Southwest

Southwest adds a requirement worth checking before you buy any scooter: "The battery must be easily removeable without the use of tools."

Hard size and weight limits:

• Cargo compartment doors measure 48" wide × 35" high
• Devices exceeding 34" in height, or 45" in width or depth with parts removed, "will not be accepted for travel"
• Devices over 500 pounds are not accepted

One inconsistency worth knowing about: Southwest's help article limits width or depth to 45", while its own PDF form states the maximum as 45" wide × 34" high. If your device is close to either figure, call rather than guess.

Cabin storage: Southwest is the only carrier that guarantees a closet on every aircraft — "Each plane has a wheelchair storage compartment to stow at least one standard-size, adult, collapsible wheelchair on a first-come, first-served basis." That is for manual chairs; your powered scooter still goes in the hold.

Fees are explicitly waived: "Wheelchairs and mobility aids checked by Customers with disabilities are exempt from our standard checked baggage fees." You choose gate or bag claim for the return. Southwest publishes a Wheelchair / Mobility Aid Information Form (revised 08/2025) and asks you to complete it before you arrive.

JetBlue

"JetBlue will accept battery-powered wheelchairs and mobility aids as checked items only."

— JetBlue — Mobility and Wheelchair Assistance

"Any lithium-ion battery that's been removed from an assistive device must be transported in the cabin with the terminals properly protected, but may not contain more than 300 watt hours or 25 grams of lithium."

— JetBlue

Removal is conditional rather than automatic: "If a wheelchair or mobility device does not have a protective housing for a lithium-ion battery, the lithium-ion batteries must be removed." JetBlue also commits not to take your device apart unnecessarily — it "will not disassemble any battery powered assistive device when the battery is non-spillable unless directed to by our HazMat specialists."

JetBlue cargo bin doors

A benefit worth claiming: if your device won't fit the aircraft on your preferred flight, JetBlue will refund the fare difference for the flight you had to take instead. Request a CRO and supply your device's dimensions, a screenshot of the fare you couldn't book, and the itinerary you did fly.

There is no published notice deadline — JetBlue asks you to add a Special Service Request via Manage Trips, and notes "there's never a fee to add an SSR to an existing booking." You choose gate or bag claim for the return.

United Airlines

United publishes the clearest explanation of the underlying federal rule of any carrier.

"If you have a collapsible mobility device, the battery must be removed and can't exceed 300-watt hours. A maximum of one spare battery not exceeding 300-watt hours or two spares not exceeding 160-watt hours each must be carried on."

— United — Wheelchairs and mobility devices

"There is no watt-hour limit for the battery installed in the device."

— United

For non-collapsible devices United applies a practical test: "Batteries will be left attached whenever the scooter and/or wheelchair will fit upright through the aircraft bin door." If it doesn't fit, staff will ask you how to disassemble it — which is why knowing your own device matters.

United is the only carrier that requires advance notice:

"Advance notice of forty-eight (48) hours is required for powered wheelchairs and you must arrive an hour earlier than the published airport check-in processing time of your originating airport if you'll be traveling on an aircraft of 60 seats or less."

— United

See the rights section below — federal law limits when that requirement can actually be enforced.

United states the fee position plainly: "We'll accept your wheelchair or other assistive device in addition to your checked baggage allowance at no additional charge." Every aircraft has "adequate space to accommodate at least one adult-sized wheelchair," and folding chairs get preboard priority.

Damage claims have the tightest clock of any airline here: file a report at the airport immediately on landing, then email "within 24 hours of arrival for domestic flights, and within seven days of arrival for international flights." Assistive Device Desk: 1-866-261-2395.

Delta Air Lines

The most permissive on batteries, and the only one where the paperwork is genuinely mandatory.

"Lithium-ion batteries have no restrictions. Follow the steps in our 'Bring Your Personal Wheelchair' section."

— Delta — Wheelchair Services

Delta permits the battery to stay installed where the device "must possess a defect-free battery in a rigid compartment that is integral to the device, as well as an effective method of preventing accidental activation during transport" — then adds, without elaborating, that "There are still circumstances that require the battery be disconnected." Delta does not publish what those circumstances are. Travel able to remove your battery, and call 404-209-3434 if you need certainty for a specific route.

The form is required, not suggested:

"Print the required Mobility Device Handling Form before your trip and bring it with you on the day of travel"

— Delta — Wheelchair Services

It asks for battery type, a watt-hours figure, device dimensions and weight, your method of preventing accidental activation, and whether the device may be tilted or loaded on its side. Know your watt-hour number before you reach the counter.

Delta publishes a general cargo figure of 13" × 36" × 42" with the caveat "limits vary by aircraft," plus an interactive fit checker on its wheelchair services page — enter your folded height and width and it returns the aircraft that will take it. Notice is 48 hours recommended, and you should check in at the counter an hour early if checking a powered device. Cabin stowage is restricted to devices that are not battery-operated.

American Airlines

American publishes no watt-hour limit for mobility device batteries at all. That is the story. Instead:

"For battery operated mobility devices, contact Special Assistance to make sure the battery type is approved for travel."

— American Airlines — Mobility and medical devices

"Batteries must be labeled by their manufacturer with the type of battery in the device: Lithum ion, Non-spillable dry cell, Wet cell."

— American Airlines (misspelling is American's own)

The watt-hour figures elsewhere on American's site — under 100 Wh, 100–160 Wh, 160–300 Wh — govern spare and portable batteries generally, not wheelchair batteries. Don't assume they transfer.

Two things American does state clearly. Electric wheelchairs with spillable batteries are not allowed. And non-collapsible or battery-powered wheelchairs "can be checked at the ticket counter."

American's 737 fleet has the lowest cargo door of any aircraft in this guide:

Closets are available only on aircraft with 100 or more seats, holding one collapsible wheelchair. Detachable parts — footrests, joysticks, cushions — may come into the cabin and "won't count toward your carry-on baggage allowance."

Damage deadlines are strict: report within 24 hours domestic or 7 days international, at a Baggage Service Office before leaving the airport, then submit online within 7 days via centralbaggage.aa.com. Special Assistance: 800-237-7976; TTY 800-735-2988; Disability Team 800-892-3624.

Does the ZiiLIF R3b clear all six?

Folded, the R3b measures 37.4" × 21.9" × 18.1" and weighs 41 lb with its battery. The battery is 25.2 V / 10.4 Ah — 262 Wh — and removes by hand without tools.

Where we'd rather be honest than reassuring. The R3b's folded height of 18.1" clears every published cargo door figure above with room to spare. But Delta's general 13" × 36" × 42" spec has a 13" dimension that the R3b exceeds, and Delta says limits vary by aircraft. Run your actual routing through Delta's fit checker rather than assuming — particularly on regional aircraft, which are the real constraint on every airline.

See full specifications on the ZiiLIF R3b product page, the spare battery, or our ultralight folding scooters.

Your rights — these apply on every airline

The Air Carrier Access Act gives you protections no airline policy can reduce.

Advance notice is limited by law. Under 14 CFR 382.27, the most notice an airline may require is 48 hours, and only for a short closed list — including an electric wheelchair on an aircraft with fewer than 60 seats. On a mainline jet, no notice requirement attaches at all. United's 48 hours and Delta's recommendation make your day smoother; they are not conditions of carriage.

Your device flies free. Assistive devices don't count toward baggage allowances or attract fees.

It has priority in the hold. Under 14 CFR 382.125, wheelchairs get priority stowage over other cargo. You are entitled to be told, before the cabin door closes, whether your device was loaded.

Gate return is your right. Devices are returned "as close as possible to the door of the aircraft" unless you asked for baggage claim.

Damage compensation is based on purchase price. Under 14 CFR 382.131, the basis is "the original purchase price of the device" — ordinary baggage liability caps do not apply.

Ask for a CRO. Every airline must provide a Complaints Resolution Official at the airport, in person or by phone, at no cost (14 CFR 382.151). A CRO can overrule other staff on disability matters, with the single exception of a pilot-in-command safety decision.

Two deadlines. File a written disability complaint with the airline within 45 days to preserve its obligation to respond. The DOT will refer complaints received within six months — airconsumer.dot.gov, or the DOT Disability Hotline on 1-800-778-4838.

Note: DOT's 2024 wheelchair rule added a 24-hour delivery standard for delayed devices and a loaner-notice requirement, but enforcement discretion notifications ran through 4 August 2026. Confirm current enforcement posture before relying on those specific provisions.

Pre-flight checklist that works on any airline

1. Know your watt-hours. Volts × amp-hours. Write it down. Delta's form has a blank for it and Alaska will want to read it off the battery.
2. Check the battery label is legible and in English, showing either watt-hours or volts and amp-hours. Alaska refuses batteries labelled in other languages. If yours isn't, bring the manufacturer's spec sheet.
3. Print the airline's form — Delta, Southwest, Alaska and JetBlue all publish one. Delta's is mandatory.
4. Measure your device folded, height and width, and compare against the cargo door table for your actual aircraft — not the airline generally.
5. Pack spares in your carry-on, terminals taped or in original packaging. Never checked, on any airline.
6. Carry detachable parts on — armrests, cushions, joysticks, bags. They don't count against your allowance.
7. Arrive early. An hour before normal check-in on Delta and United; two hours on Alaska.
8. Inspect before leaving the jet bridge. Report damage there, not at home. United and American both run a 24-hour domestic clock.

Frequently asked questions

What is the watt-hour limit for a mobility scooter battery?

300 watt-hours on Alaska, Southwest, JetBlue and United (for collapsible devices). Delta publishes no limit for lithium-ion wheelchair batteries. American publishes no limit for mobility devices and asks you to call Special Assistance. The 100 Wh and 160 Wh figures widely quoted online apply to consumer electronics, not mobility devices.

Can I keep my mobility scooter with me in the cabin?

No. Every airline here requires powered scooters to travel in the cargo hold. Cabin closets — required by 14 CFR 382.67 on aircraft with 100 or more seats — are for manual folding wheelchairs only.

Which airline is strictest about mobility scooter batteries?

Alaska. It refuses any device whose battery is fully enclosed and not easily removable, requires the battery to travel in the cabin, and requires the label to be legible and in English.

Do I have to give the airline 48 hours notice?

Only United requires it. Delta recommends it. Under 14 CFR 382.27, an airline may only require 48 hours notice for an electric wheelchair on aircraft with fewer than 60 seats.

Where does my spare battery go?

Carry-on, always, with terminals protected. Spare lithium batteries are prohibited in checked baggage on every airline, including a carry-on bag that ends up gate-checked.

Does my scooter count against my baggage allowance?

No. Assistive devices are carried free and don't count toward carry-on or checked allowances. United and Southwest state this explicitly; the rest are bound by the Air Carrier Access Act regardless.

Is there such a thing as an FAA-approved battery?

No. Alaska states directly that despite manufacturers' claims, there are no FAA-, ICAO- or IATA-approved batteries. What matters is whether your battery meets the published watt-hour limits and can be verified at the counter.

What if the airline damages my scooter?

Report it before leaving the airport and ask for a Complaints Resolution Official. Compensation is based on the device's original purchase price, not baggage liability limits. United and American both require a report within 24 hours for domestic flights.
