If your incoming flight is late and you miss a connection, who pays for the rebooking depends almost entirely on whether both flights share a single PNR. Single PNR: the airline is responsible and must rebook you at no cost (under certain DGCA conditions). Separate tickets: you are on your own and the second airline owes you nothing. The airport minimum connection time is the practical threshold that matters most.

TL;DR — the critical liability split

If you miss a connecting flight in India because your first flight was delayed, the question of who pays depends on one thing: are both flights on the same PNR? Single PNR (same booking reference, typically because you bought a connecting itinerary through an airline or OTA as one ticket): the airline is responsible for rebooking you on the next available flight at no additional cost, provided the delay was within the airline's control. Separate tickets (you booked each leg independently, even on the same airline): the second airline is under no obligation to rebook or refund you — you missed their flight, full stop. You will have to buy a new ticket.

What is a PNR and why does it matter so much?

PNR stands for Passenger Name Record — the alphanumeric booking reference (like 'AB1234') that identifies your reservation. A single PNR containing both your connecting flights means the airline's system treats your journey as one connected itinerary. The airline knows flight 2 is your connecting flight because it is in the same booking, and — critically — it knows that if flight 1 is late, flight 2 is at risk.

When you hold two separate PNRs (you booked flight 1 on one reference and flight 2 on a completely separate booking, even if the same airline), the systems treat them as two unrelated journeys. The second airline's check-in system does not know or care about the first flight. From their perspective, you are a no-show.

This matters practically because:

What DGCA rules say about missed connections due to airline delay

The Directorate General of Civil Aviation (DGCA) publishes passenger rights guidelines under the Civil Aviation Requirements (CAR), Section 3, Series M, Part IV — this is the document that governs compensation, refunds and rebooking in India. Key points relevant to missed connections:

When an airline delay causes you to miss a connection that was part of the same ticketed itinerary (single PNR), and the delay is due to a reason within the airline's control (mechanical issues, operational decisions), the airline is required to:

Compensation beyond this (cash payments for delay) applies under specific thresholds and conditions — check the current CAR Section 3 document on the DGCA website (dgca.gov.in) for the precise rules, as these are updated periodically. The key exemption: airlines can cite 'extraordinary circumstances' (severe weather, ATC restrictions, security issues) to avoid rebooking liability even on a single PNR. Air Traffic Control delays and genuine weather events — which are common at Indian airports during the monsoon — typically fall under this exception.

For separate PNRs, the DGCA rules are essentially irrelevant to the connection problem because the second airline's contract with you begins and ends with that ticket — they are not party to what happened on your first flight.

Minimum connection times at Indian airports — what you need to know

Minimum connection time (MCT) is the shortest time allowed between the scheduled arrival of your inbound flight and the scheduled departure of your outbound flight, within which an airport and airline system considers the connection 'protected' in case of delays. MCTs vary by airport, whether you are staying in the same terminal, and whether you need to go through security again.

Rough MCT figures for major Indian airports — treat these as indicative, as airlines update these periodically:

If you book a connecting itinerary through an airline or OTA as a single ticket, the booking system (GDS or the airline's own) will typically enforce MCT — it will not allow you to book a connection that is shorter than the minimum. If you are creating your own connection by buying two separate tickets, the system has no constraint and you could inadvertently book an impossible connection.

When separate tickets can actually work — and how to hedge

I am not saying never book separate tickets. Sometimes a much cheaper one-way on each leg is worth the risk — particularly if the connection buffer is generous (3+ hours), the inbound is consistently reliable, and the cost saving is substantial. But go in with eyes open:

What to do if you actually miss a connection in India

If it happens — here is the practical sequence:

  1. Single PNR situation: Go directly to the airline's transfer desk or customer service counter in the arrival hall before you leave the secure area (if domestic-to-domestic on the same terminal). Do not go to the check-in queue — the transfer desk handles exactly this. Show your PNR, explain the inbound delay. They should rebook you at no charge on the next available flight. If there is a significant wait (more than a few hours), ask about meal vouchers and, if overnight, hotel accommodation.
  2. Separate PNR situation: You are buying a new ticket. Call the airline (IndiGo: 0124-6173838, Air India: 1860-233-1407 or their website) immediately to check the next available flight and price. Booking on the app often shows the same price as the counter, and is faster. Keep all receipts — if your travel insurance covers missed connections, you will need documentation of the inbound delay (ask the first airline for a delay certificate) and the new ticket purchase.
  3. If the delay was the airline's fault on a single PNR and they are giving you trouble: Quote the DGCA CAR Section 3 M IV guidelines. Escalate to the supervisor. If all else fails, file a complaint with the DGCA through the AirSewa portal (airsewa.gov.in). I have seen airlines suddenly find a solution once they know a passenger knows their rights.

When booking connecting itineraries, the safest approach is always to book through the airline's own website as a single itinerary, or through an OTA as a single booking (verify the OTA issues one PNR, not separate). For complex multi-leg trips, consider using FlightGPT to compare connecting itinerary prices with same-airline routing versus separate one-ways — the price difference is sometimes surprisingly small, and the protection you get from a single PNR is worth the small premium.

Frequently asked questions

If I have a single PNR and my first flight is delayed, does the airline have to rebook me on the next flight?

Yes, under DGCA passenger rights guidelines (CAR Section 3, Series M, Part IV), if the airline's delay causes you to miss a connection that was part of the same ticketed itinerary (single PNR), the airline must rebook you on the next available flight at no additional charge — provided the delay was within the airline's control. Weather events and ATC restrictions are typically excluded as 'extraordinary circumstances'. The DGCA website (dgca.gov.in) has the current guidelines.

I booked two separate tickets. Can the second airline refuse to board me?

Yes. With separate PNR tickets, each airline's obligation starts and ends with their own leg. If you miss the second flight because the first was late, the second airline will treat you as a no-show. You will need to buy a new ticket at whatever the current price is. Travel insurance with a missed connection clause is your main financial protection in this situation.

What is the minimum connection time at Delhi Airport between two domestic flights?

For same-terminal domestic-to-domestic connections at Delhi's IGI Airport, around 40–60 minutes is the typical minimum. However, if your connection is between Terminal 2 and Terminal 3 (which requires a bus transfer), allow at least 90 minutes of scheduled buffer. During peak hours and monsoon season, allow more. Always check the terminals of both flights at the time of booking.

What if I am connecting from an international flight to a domestic flight in India on separate tickets?

International-to-domestic connections on separate tickets are very high risk in India. You must clear customs, collect baggage, go through security again, and potentially re-check bags — this process typically takes 1.5–3 hours at Delhi and Mumbai depending on the queue. Allow a minimum of 3 hours of buffer, preferably 3.5–4 hours during busy periods. On a single PNR (through-ticketed itinerary), the airline handles the connection — but international-to-domestic same-PNR tickets from foreign carriers rarely exist for Indian domestic connections; you usually have to buy separately.

Does travel insurance cover a missed connecting flight in India?

Some travel insurance policies include 'missed connection' coverage — if your inbound is delayed by more than a specified threshold (typically 2–3 hours) and you miss a separately purchased connecting flight, the insurer reimburses the cost of a new ticket up to a policy cap. Read the policy terms carefully: some policies only cover international trips, and the trigger delay duration varies. Domestic India missed connection cover is less commonly included — check before buying.

What should I do if an OTA says they booked me on a 'combo' itinerary — is that a single PNR?

Not necessarily. OTA combo bookings bundle two one-ways for convenience but often generate two separate PNRs — meaning each leg is on a separate contract with its respective airline. To verify: look at your booking confirmation and check if both legs show the same alphanumeric booking reference code. If each leg has a different reference, you effectively hold separate tickets and should plan accordingly — including allowing generous connection buffer time.
