Travelling with an elderly parent on supplemental oxygen is one of the most stressful logistics challenges in family travel. The rules around portable oxygen concentrators (POCs) on Indian flights — which devices are allowed, how far in advance you must inform the airline, and what battery capacity you need — are specific and unforgiving. Here's everything you need to know before you book.
TL;DR: Key Rules for POCs on Indian Flights
Only FAA-approved portable oxygen concentrators are allowed on passenger aircraft in India. You must inform the airline in advance — IndiGo requires 48 hours, Air India requires 72 hours for international routes. Your batteries must have at least 150% of the flight duration's capacity. You need a MEDIF (Medical Information Form) completed by a doctor and accepted by the airline's medical team before flying. The POC must be used only from your own power supply, never from aircraft power, unless the airline explicitly approves it.
Why Only FAA-Approved POCs Are Allowed
Aircraft cabin air is pressurised to around 6,000–8,000 feet equivalent altitude, and POCs generate oxygen by concentrating ambient air. Any device operating on a passenger aircraft must meet international safety standards — specifically, for POCs, the FAA (US Federal Aviation Administration) maintains an approved device list that is widely adopted by airlines globally, including Indian carriers.
If your relative's POC isn't on the FAA-approved list, it cannot be taken on the flight. Period. This catches families off guard when they've bought a device from a local medical supply shop without checking the aviation compliance. Common approved devices (as of the FAA's published list) include units from manufacturers like Philips Respironics, Invacare, Inogen, and AirSep — but the approved list is updated regularly, and you must verify your specific model number on the FAA website (faa.gov), not take a seller's word for it.
Devices that are not POCs — meaning cylinders of compressed oxygen, liquid oxygen — are not permitted on passenger aircraft cabins in India. If someone requires oxygen but doesn't have a FAA-approved POC, they need to arrange for airline-provided oxygen (which Air India can sometimes arrange on certain routes for an advance fee) or reconsider the travel plan. Confirm the specific aircraft and route capability directly with Air India's special assistance team.
Advance Notice Requirements: IndiGo vs Air India
This is where families make the mistake that costs them a seat.
IndiGo: Requires a minimum of 48 hours advance notice before departure to travel with a POC. You notify them through their 'Special Assistance' section online or by calling their customer care. They will ask for the device model, FAA approval status, and may request a medical certificate or fitness-to-fly form. IndiGo doesn't currently operate long-haul international flights, so most POC travel on IndiGo is domestic.
Air India: For domestic routes, 48 hours is typically the minimum. For international routes (which Air India operates in significant volume in 2026 — to the USA, UK, Europe, Australia, and Gulf countries), Air India requires 72 hours advance notice and goes through a more formal medical clearance process involving MEDIF (see below). Contact Air India's special assistance or medical assistance desk directly — the regular customer care line often cannot process medical clearances; you need the right department.
Akasa Air: As of 2026, check Akasa's current policy directly on their website or via customer care. Akasa is a newer carrier and their medical assistance procedures may differ from IndiGo and Air India. Don't assume — always confirm in writing.
SpiceJet: SpiceJet's network and operations have been constrained in 2026 — if you're considering SpiceJet for a route, verify the flight is actually operating and confirm POC policy before booking, given the airline's service disruption history.
Battery Requirements: The 150% Rule
Airlines require that your POC batteries carry at least 150% of the expected flight time in charge. So for a 2-hour Delhi–Mumbai flight, your batteries combined must provide at least 3 hours of operation. For a 9-hour Delhi–London flight, you need 13.5 hours of battery capacity.
This is significant. Most POC batteries provide 4–8 hours per battery depending on the model and flow setting. For long-haul flights, you may need 2–3 fully charged battery packs. And here's the catch: lithium battery packs over 100 Wh per battery are subject to additional restrictions, and batteries over 160 Wh per battery are typically prohibited in carry-on baggage without airline approval. Check the Wh rating of your specific battery against these thresholds.
Practical tips:
- Carry all POC batteries in your carry-on, not in checked baggage. Lithium batteries in checked baggage is prohibited under aviation safety rules.
- Charge all batteries fully the night before travel. Confirm with your POC manufacturer the actual runtime at the flow rate your relative requires — manufacturers' stated battery life is often at low flow settings.
- Bring a spare charging adapter for layovers.
- Label each battery with your name and flight details in case of security query.
MEDIF: What It Is and How to Get One
MEDIF stands for Medical Information Form. It's an IATA-standard form that your doctor fills out, describing the passenger's medical condition, their oxygen requirement (flow rate in litres per minute), and their fitness to fly. Airlines use it to assess whether they can safely carry the passenger and what arrangements need to be made.
The process works roughly like this:
- Contact the airline's medical or special assistance desk and request a MEDIF form. Air India has a MEDA desk; IndiGo may use a simplified version for domestic routes.
- Your relative's treating doctor (the one managing their oxygen therapy — often a pulmonologist or cardiologist) completes the form. This is not something a GP who doesn't know the patient's case can do quickly — plan for this to take a few days.
- Submit the completed MEDIF to the airline's medical team. They review it and issue clearance (or, occasionally, decline if the passenger's condition is too unstable for air travel).
- Airline clearance is typically valid for a set period (often around 30 days) — if your travel dates change significantly, you may need a fresh MEDIF.
The MEDIF process is not optional for POC users on Air India international routes — it's required. For IndiGo domestic routes, the process may be less formal (a doctor's fitness-to-fly certificate is sometimes accepted), but confirm with IndiGo before assuming a simpler process applies to your situation.
On the Aircraft: Using Your POC During the Flight
Once you're on board with clearance, a few operational things to know:
- The POC must be used only from your own battery supply, not plugged into the aircraft power outlet — unless the airline has specifically approved this for your device and seat. Most airlines don't allow POCs on aircraft power (the power socket is for laptops and phones; POCs draw more and some interfere with aircraft systems). Carry enough battery charge to not need aircraft power.
- The POC generates some noise (a slight cycling sound) — sit where this is least disruptive to other passengers. Bulkhead rows or window seats away from other passengers are preferable.
- During takeoff and landing, cabin pressure changes. Your POC's oxygen concentration may momentarily vary. Your doctor should have assessed whether your relative can tolerate this — it's part of what the MEDIF process establishes.
- Inform the cabin crew that you're using a POC as soon as you board. They need to know for safety reasons and in case of any emergency evacuation planning.
Booking the Flight and Getting Help
When booking flights for a family member requiring a POC, choose the airline and route first based on which one can actually accommodate your needs, not purely on price. Air India's wider aisle on some international aircraft (777, 787 variants) can be more accommodating for passengers with medical equipment.
Use FlightGPT's flight search to compare route options and timings — then contact the airline directly to confirm POC accommodation before finalising the booking. Also read our guide on wheelchair assistance codes if your relative also needs mobility support at the airport, and our Schengen visa for families guide if the destination is Europe and you need to address visa documentation alongside the medical logistics.
For elderly parents, the combination of MEDIF clearance, wheelchair assistance (usually WCHC), and POC approval needs to be sorted together as one package — not as three separate last-minute requests. Start the process at least 3–4 weeks before travel for international routes, not 72 hours.
Frequently asked questions
Which portable oxygen concentrators are allowed on Indian flights?
Only FAA-approved POCs are permitted. The FAA maintains an official list of approved POC models on their website (faa.gov). Common approved brands include Philips Respironics, Invacare, Inogen, and AirSep, but you must verify your specific model number against the current FAA list — approval applies to specific models, not entire brands.
How many hours before departure must I tell IndiGo about a POC?
IndiGo requires a minimum of 48 hours advance notice. Notify them through their website's Special Assistance section or by calling customer care. For domestic routes, IndiGo may accept a doctor's fitness certificate alongside the notification; confirm what documentation they need for your specific situation when you notify them.
How much battery capacity do I need for a POC on a Delhi–London flight?
Apply the 150% rule to the total expected flight time. Delhi–London is roughly 8.5–9 hours. You need at least 13–14 hours of battery capacity. That typically means 2–3 fully charged battery packs depending on your POC model and the flow rate required. Carry all batteries in your cabin baggage — lithium batteries are not permitted in checked luggage.
What is MEDIF and does every POC user need one?
MEDIF is an IATA Medical Information Form completed by the passenger's treating doctor, establishing their medical condition and fitness to fly. Air India requires MEDIF for POC users on international routes; IndiGo domestic may use a simpler fitness-to-fly letter. Contact the airline's medical or special assistance desk to get the right form for your route. Allow several days for the doctor to complete and the airline to review it.
Can I plug my POC into the aircraft power socket?
Generally no — airlines typically prohibit using POCs on aircraft electrical sockets unless the airline's medical team has specifically approved it for your device. The aircraft power is certified for low-draw devices like laptops. Plan to run entirely on your own batteries for the full flight duration plus a reasonable buffer.
What if Air India's medical team declines to clear my relative to fly?
Airlines can decline to carry passengers whose medical condition may deteriorate in flight or who pose a safety risk. If clearance is declined, ask for the specific reason in writing. Your relative's doctor may be able to address the concern (for example, by adjusting the prescribed flow rate or providing additional stabilisation documentation). In some cases, a ground medical assessment closer to the travel date might result in clearance — work with the treating physician and the airline's MEDA desk to find a path forward.
