US Airline Rules for CPAP, POC & Assistive Devices in the Cabin (2026)

Compare CPAP, POC, battery, and mobility-aid cabin rules for 12 US airlines. Policy-only guide with official sources. BagRule does not give medical advice.

YMYL disclaimer

BagRule does not give medical advice. This guide only summarizes airline and DOT/FAA carriage and approval policies for medical and assistive devices in the cabin. It does not tell anyone which device to use, how to treat a condition, whether travel is medically appropriate, or whether a device is “safe” for a person. Always confirm rules on the operating airline’s official special-assistance / medical-device pages (and DOT/FAA links below) before you fly. Policies change; codeshares follow the operating carrier.

Quick answer

On most US airlines in this set, an FAA-labeled (or listed) POC and many battery-powered CPAP / respiratory devices may be carried and used in the cabin as assistive devices under DOT Part 382 and each airline’s page, usually without counting as a regular bag. Airlines may require advance notice, a physician / airline form (varies), and enough charged batteries (DOT often cites ≥150% of expected flight duration). Compressed / liquid oxygen is generally not allowed. Confirm the operating airline list and battery rules before you fly. BagRule does not give medical advice.

What regulators say (high level - not medical advice):

Under the Air Carrier Access Act and 14 CFR Part 382, covered U.S. carriers generally must allow a passenger with a disability to use certain passenger-supplied electronic respiratory assistive devices in the cabin on aircraft originally designed for more than 19 seats when the device meets applicable FAA criteria, including POCs, ventilators, respirators, and CPAP machines that display a manufacturer label indicating FAA acceptance (legacy listed models may also be accepted without that label). Airlines may require, among other things:

  • Up to 48 hours’ advance notice to use a ventilator, respirator, CPAP, or POC onboard
  • Early check-in (often 1 hour before general check-in)
  • A physician’s statement / medical certificate for POC use (airline-specific)
  • A supply of fully charged batteries for no less than 150% of the expected flight duration (DOT/FAA consumer guidance)

Assistive devices (including many medical devices and mobility aids) are generally not charged as baggage when required under Part 382. Airlines may charge for optional services such as carrier-supplied medical oxygen where offered.

Decision checklist

Before you travel (policy checklist - not medical advice):

  1. Contact the operating airline special-assistance / accessibility desk (or add the SSR in Manage Booking) for your device type.
  2. Check the airline’s approved POC list and/or FAA label. Do not rely on third-party brand lists.
  3. Confirm battery rules (often ≥150% of expected flight duration; spares in carry-on; terminals protected). Do not invent Wh limits: use the airline page / FAA PackSafe.
  4. Download / complete any required form (e.g. United POC form, Frontier Form 30881, Delta OxygenToGo authorization) if the airline requires it for use onboard.
  5. Plan seating: many carriers require window-side seating and ban exit/bulkhead when a POC is used under-seat.
  6. Mobility aids: ask about gate-check / cabin closet / cargo and battery labeling. Personal mobility aids are generally free as assistive devices when Part 382 applies.
  7. Codeshares: follow the operating carrier’s medical-device page.

At the airport (3 steps)

  1. Check in with an agent early (many airlines ask for ~1 hour before general check-in, or a published earlier time such as Avelo’s 90 minutes). Bring forms, device, and spare batteries in carry-on.
  2. Have the device verified (model / FAA label, phases of flight when you’ll use it, battery count/packaging). Get any boarding-pass indicator the airline uses (e.g. Southwest).
  3. At the gate / onboard, sit only where the airline/FAA seating rules allow. Stow the device under the seat (or as the airline directs for taxi/takeoff/landing). Do not rely on aircraft power unless the airline expressly allows it for that device.

Tips

  1. Screenshot or print the airline’s current medical-device / POC page and any confirmation email for the airport.
  2. Pack spare batteries in the cabin, terminals protected (plastic bag / recessed terminals / manufacturer packaging). Never invent a Wh number; check PackSafe + airline.
  3. Empty humidifier water before security if your device has a water chamber (common airline/TSA practice note; confirm TSA + airline).
  4. If connecting on another airline, re-check that carrier’s POC/CPAP rules.
  5. For mobility devices, label the device and bring disassembly / battery instructions for ramp staff.

FAQ

Does a CPAP count as a carry-on on US airlines?
Often no. Many carriers treat CPAP / respiratory devices as assistive devices that don’t count toward the standard carry-on/personal-item limit when packed as the device (not mixed with clothes). Confirm on your airline’s medical/assistive page (examples: American mobility page; JetBlue medical-devices page; Frontier special services; Delta medical devices). BagRule does not give medical advice.
Can I use a portable oxygen concentrator (POC) on the plane?
Covered US airlines generally must allow an FAA-compliant POC (manufacturer FAA-acceptance label and/or listed legacy model) under 14 CFR § 382.133, subject to airline procedures (notice, forms, batteries, seating). Compressed/liquid oxygen is typically prohibited. See DOT POC guidance and your airline’s list. Do not use a third-party “approved brands” list as authoritative.
How many POC batteries do airlines require?
DOT consumer guidance and most airline pages in this set require enough fully charged batteries for about 150% (1.5×) of expected flight duration (some also count connections/airport time). Exact wording varies: cite the airline page. If Wh limits appear (e.g. JetBlue’s POC 100 Wh bullet), quote only what’s published.
Do I need a doctor’s note?
It depends on the airline and whether you will use the device onboard. Examples published 2026-09-16: United POC physician form for use; Frontier Form 30881 / physician statement for POC; Delta OxygenToGo process; JetBlue states FAA no longer requires physician documentation for POC use (airline may still verify operation/flow). CPAP often needs no medical authorization on some carriers (e.g. Frontier respiratory devices). Always check the operating airline.
Are wheelchairs and mobility aids free?
Under DOT disability rules, airlines generally must transport assistive devices including wheelchairs without counting them as regular baggage. Carriers in this set publish free carriage language (e.g. Frontier special services; Avelo special services; Sun Country special services; American mobility page). Battery/hazmat rules still apply.
Reddit said my nebulizer / CPAP was confiscated—what’s the official rule?
Follow the operating airline medical-device page and TSA screening pages. Example: JetBlue lists nebulizer as carry-on/checked yes, onboard use no. Alaska states advance notice is not required for certain MPEDs including nebulizers/PAP. BagRule does not give medical advice - only policy pointers.
