If you are flying with a parent who had a recent surgery, stroke, or a serious cardiac event, the airline may ask for a MEDIF (Medical Information Form) before they allow boarding. Air India and IndiGo both require it for certain conditions — and the form needs to reach the airline at least five days before departure, not at the check-in counter.
TL;DR — what is MEDIF and do you actually need it?
MEDIF stands for Medical Information Form, an IATA-standard document that your doctor fills to confirm a passenger is medically fit to fly. You need it if your family member has a condition that could be aggravated by cabin pressure, low oxygen, or limited mobility — such as a recent heart attack, post-surgery recovery, unstable angina, recent stroke, or severe respiratory illness. In India, Air India and IndiGo both require it for these conditions, and so does Air India Express on international routes. The submission deadline is typically five working days before departure, sometimes more — not something you sort out at the airport. Get the form from the airline's website or special-assistance desk, have your doctor fill it, and email it to the airline's medical desk well in advance.
When does a family member actually need a MEDIF?
This is the question every family gets wrong: they assume the airline will flag it if something is a problem. They won't — unless you proactively disclose the condition at booking. Here is the rough guide, though you should verify with your specific airline before assuming:
- Definitely required: recent heart attack or cardiac surgery (typically within 3–6 weeks), active deep vein thrombosis (DVT), stroke within the past few weeks, oxygen dependency, communicable disease under isolation protocol, recent chest or abdominal surgery with unhealed wounds, severe anaemia.
- Likely required: pregnancy beyond 36 weeks (28 weeks for multiples), severe diabetes with recent complications, epilepsy with recent uncontrolled seizures, psychiatric conditions requiring sedation during flight.
- Airline discretion: stable COPD, controlled heart failure, dialysis patients, wheelchair users with pressure-sore risk on long flights.
My own experience helping my father-in-law fly from Kochi to Delhi after a hip replacement: IndiGo requested the MEDIF and a 'fit to fly' letter from his orthopaedic surgeon. No one told us at booking — we found out only when we called their special assistance line three days before departure, which was too close to the deadline and caused a genuinely stressful scramble. Don't do what we did.
The DGCA (Directorate General of Civil Aviation) sets the overarching regulatory framework for passenger special assistance on Indian carriers; airlines then implement their own internal medical desks within those guidelines. You can check DGCA's civil aviation requirements at dgca.gov.in.
How to get the MEDIF form — step by step
The process varies slightly by airline but the bones are the same:
- Identify the need early — at the time of booking, or as soon as a medical event occurs. Don't wait until a week before.
- Download or request the form:
- Air India: the MEDIF form is available at airindia.com under 'Special Assistance'. Their medical desk is medassistance@airindia.in — confirm the current email before sending.
- IndiGo: request via their special assistance contact or through the IndiGo website. IndiGo's form is slightly simplified compared to the full IATA MEDIF, but covers the same clinical ground.
- Akasa Air and Air India Express: similar process; call their customer desk to request the form.
- Your treating doctor fills Part B of the MEDIF — the clinical section. This is the section that confirms the diagnosis, current stability, fitness for pressurised cabin, any special needs (oxygen, stretcher, wheelchair), and whether a medical escort is required.
- You fill Part A — passenger contact details, flight information, any special equipment being carried (portable oxygen concentrator, wheelchair, medication).
- Submit at least 5 working days before departure — Air India and IndiGo both state this on their special assistance pages. Some cases (stretcher travel, in-flight oxygen) need even more lead time because the airline has to arrange equipment and crew briefings. International flights, especially Air India's long-haul routes, often need 7–10 days.
- Get written confirmation — don't just email and assume. Follow up by phone and keep the written airline approval with you at check-in. Gate staff need to see it.
What happens if you skip the MEDIF and show up at the airport?
The airline can and does deny boarding. This is not a theoretical risk — it happens more often than families expect, particularly at busy metro airports where gate staff are following checklist protocols. If you show up with a post-cardiac-surgery parent without prior clearance, the gate supervisor calls the airline's duty medical officer, who may decline boarding on liability grounds. There is no appeal process at the gate. You lose your tickets, you scramble for a rebook, and you have a distressed elderly parent in an airport terminal — a genuinely awful situation.
Even if you somehow get through check-in, the captain has the final authority to refuse carriage if they believe a passenger poses a medical risk. Under DGCA rules, airlines are also required to have trained cabin crew capable of basic first aid, but they are not equipped for cardiac emergencies — a MEDIF is partly about ensuring the flight is actually safe for the passenger.
One more thing: travel insurance. If a passenger boards without disclosing a pre-existing condition and something goes wrong in-flight, the insurer can deny the claim on non-disclosure grounds. The MEDIF process is also your paper trail that the condition was known, disclosed, and cleared.
Travelling with portable oxygen or medical equipment
If your parent needs supplemental oxygen during the flight, things get more specific. Commercial aircraft cabins are pressurised to the equivalent of roughly 6,000–8,000 feet altitude, which means oxygen partial pressure is around 15–17% lower than at sea level. For someone with borderline oxygen saturation at rest, this matters.
- In-flight oxygen from the airline: Air India can provide in-flight medical oxygen for a fee (around a few thousand rupees, but verify the current rate and book well in advance via their medical desk — it is not available on all aircraft types). IndiGo does not provide supplemental oxygen as a standard service — passengers needing it must carry an approved POC.
- Portable Oxygen Concentrators (POC): IATA and DGCA permit approved POC models in the cabin. The passenger must carry a doctor's letter, the POC must be FAA-approved (most reputable brands like Inogen, Respironics and Philips are), and the airline must be notified in advance. You'll need enough battery for 150% of the flight duration. Liquid oxygen cylinders are banned on commercial aircraft.
- Wheelchairs and mobility aids: Airlines must provide wheelchair assistance free of charge under DGCA civil aviation requirements. Request it at booking and again at check-in. Power wheelchairs with lithium-ion batteries have separate notification requirements.
For families booking an international leg, the same MEDIF applies — you may need to coordinate with the destination country's aviation authority requirements too, especially for US or EU-bound flights.
IndiGo vs Air India special assistance — practical differences
Both airlines handle MEDIF cases, but the experience on the ground is noticeably different:
Air India has a dedicated medical desk staffed by doctors, has more experience with complex cases (partly because it operates long-haul routes where in-flight medical incidents are more likely), and can accommodate in-flight oxygen and stretcher cases on wide-body aircraft. Their response time on MEDIF submissions can be 2–4 working days — the 5-day lead time exists partly to absorb this. If you are flying your parent internationally, Air India's network and medical infrastructure is generally more suited than a low-cost carrier.
IndiGo handles a very high volume of MEDIF requests given its market share. Their form is simpler and their turnaround is often quicker for routine cases (stable post-surgery, controlled conditions). But IndiGo does not offer in-flight medical oxygen as a standard service and is generally less equipped for high-dependency medical passengers on their narrow-body A320 fleet. For domestic hops post-recovery — say, flying a parent from Mumbai back home to Coimbatore after discharge — IndiGo works fine, provided the condition is stable and the MEDIF is submitted on time.

A quick checklist before departure
- MEDIF filled by treating doctor — both Part A and Part B complete
- Submitted to airline's medical desk at least 5 working days before departure (more for international / equipment-dependent)
- Written confirmation of clearance received from airline — save the email, print a copy
- Wheelchair assistance requested at booking and re-confirmed at check-in
- Sufficient prescription medication in carry-on (not checked luggage) with doctor's letter for any controlled substances or syringes
- Travel insurance that covers pre-existing conditions — read the exclusions; many standard plans exclude known cardiac conditions unless you buy a specific add-on
- Emergency contact and hospital details at destination saved on your phone
- Arrival airport wheelchair assistance requested via airline (they coordinate with destination airport)
One last thing: book your flights a bit earlier than you normally would. Last-minute bookings leave no time for MEDIF processing, and you'll be forced to choose between rescheduling and showing up without clearance. Book at least three weeks out, submit the MEDIF immediately, and let the airline's medical desk do its job before you get to the airport.
Frequently asked questions
How many days before the flight should I submit the MEDIF form?
Air India and IndiGo both require MEDIF submission at least 5 working days before departure. For international flights, in-flight oxygen requests, or stretcher travel, the lead time is often 7–10 days. Submit as early as possible and get written confirmation — don't assume a submitted form equals an approved clearance.
Who fills the MEDIF form — the passenger or the doctor?
Both. The passenger (or family member) fills Part A, which covers personal and flight details. The treating doctor fills Part B, the clinical section, confirming diagnosis, current health status, fitness for pressurised cabin, and any special in-flight requirements like oxygen or a stretcher.
Can IndiGo provide oxygen during the flight for a patient?
IndiGo does not routinely provide supplemental oxygen as a standard service. Passengers who need in-flight oxygen on IndiGo must carry an IATA-approved Portable Oxygen Concentrator (POC) such as an Inogen or Respironics model. Air India can arrange in-flight medical oxygen on certain aircraft with advance notice through their medical desk — verify availability and the current fee directly with Air India.
What if my parent's doctor says they are fit but the airline refuses?
The airline's duty medical officer can override a treating doctor's clearance if they have operational or safety concerns. This is rare for stable, well-documented conditions where the MEDIF is complete and submitted on time. If denied, you can escalate to the airline's medical desk or, for a systemic issue, to the DGCA Consumer Grievance cell. In practice, a well-filled MEDIF from a specialist (cardiologist, orthopaedic, etc.) is almost always accepted.
Does the MEDIF expire? Can I use the same one for a return flight?
MEDIF clearance is typically granted for a specific flight or a short window (often the same trip's outbound and return, if booked close together). For a condition that changes — post-surgery recovery, for example — the airline may request a fresh MEDIF for the return leg if it is several weeks after the outbound. Confirm with the airline's medical desk when you submit the form.
Is MEDIF required for a domestic flight in India, or only international?
MEDIF can be required for both domestic and international flights in India. Any flight operated by a DGCA-regulated Indian carrier — including a 2-hour IndiGo hop from Bengaluru to Hyderabad — can require a MEDIF if the passenger has a condition that meets the airline's medical clearance criteria. International flights, especially long-haul ones, have stricter thresholds, but the form itself is the same.
