Minimum connection time (MCT) is the shortest interval an airport allows to move you and your bags from an arriving flight to a departing one. It is a per-airport floor, not a comfortable buffer. On one ticket the booking system will not sell you a connection below it; on separate tickets there is no MCT protection at all. Treat anything near the minimum as risky, especially when you change terminals.

You found a great fare with a 50-minute layover. Tempting, right? Before you book it, it helps to know what that number really means and who is on the hook if the connection falls apart.
This guide explains minimum connection time in plain terms, walks through the major Indian hubs where terminals make a big difference, and shows exactly where your protection ends.
What is minimum connection time, and who sets it?
Minimum connection time is the official shortest interval an airport allows to transfer a passenger and their luggage from an arriving flight to a connecting departure, according to IATA’s Station Standard MCT. It is set per airport, not as one global figure. IATA’s standard covers 400+ of the world’s most-connected airports.
Who decides the number? The airlines operating at that airport agree the value, and IATA then approves it before it is published to the booking systems travel agents and airlines use. So MCT is a negotiated, airport-specific floor, not a guess.
That 400+ airport list represents around 90% of all international connections, IATA reports. Separately, the 2026 third edition added roughly 3% more airports, lifting coverage to about 83% of all worldwide connections. Those are two different measures, so it’s worth keeping the qualifier straight: international connections versus worldwide connections.
The number changes by connection type too. A domestic-to-domestic transfer can be as quick as 30 minutes, while an international transfer can run up to about 90 minutes, per the OAG insiders’ guide. International runs longer because of immigration, customs and baggage recheck, and a terminal change can add another 20 to 40 minutes on top.
Is a “legal” connection actually safe to book?
A connection at or above the published MCT is “legal,” but legal is a floor, not a guarantee. On a single ticket the booking system will not sell you anything below the airport’s minimum, so any same-ticket connection you can buy is technically valid, OAG and the Navan glossary confirm. That does not make it comfortable.
Here’s the gap between “legal” and “safe.” The MCT assumes an on-time arrival, a short walk and no surprises. Real travel rarely cooperates. Weather, air-traffic-control holds, a late inbound aircraft, a long immigration queue or a terminal change can all eat a tight buffer in minutes.
One more thing that quietly shrinks the gap: check-in and boarding cut-offs. Indian domestic flights typically close check-in around 45 to 60 minutes before departure, though this varies by airline. So a “60-minute” connection can effectively be much tighter once the next flight’s gate closes.
If you want a comfortable cushion rather than the bare minimum, this is where padding the layover pays off. Our guide to short, long and overnight layovers breaks down how much breathing room each type really needs.
How tight is too tight at India’s big hub airports?
At India’s busiest hubs, the terminal layout matters more than any single minute figure. Only Mumbai and Hyderabad publish airport-sourced specifics; everywhere else, treat the numbers below as planning guidance to confirm with your airline. The table is industry-typical and illustrative, not a published guarantee.
| Connection type | Typical range (illustrative) | Why it varies |
|---|---|---|
| Domestic to domestic | ~30–60 min | Same terminal, bags often through-checked |
| Domestic to international | ~60–90 min | Possible terminal change, security recheck |
| International to domestic | ~75–120 min | Immigration, baggage reclaim, customs, recheck |
| International to international | ~75–180 min | Terminal change, long inter-concourse walks |
Ranges are industry-typical and illustrative only — airport- and airline-specific. Only OAG’s “30 min domestic / up to 90 min international” anchor is directly sourced. Confirm before booking.
Mumbai (CSMIA)
Mumbai officially recommends about 2 to 3 hours for domestic connections and about 3 to 4 hours for international, especially when changing terminals, per the Mumbai Airport transit guide. T1 (domestic) and T2 (international) are separate buildings linked by a complimentary shuttle that takes roughly 15 to 20 minutes or more, traffic-dependent.
Delhi (DEL)
Delhi’s layout is in transition, so check your exact terminals. T1 is the outlier, sitting roughly 6 to 7 km from T3 and needing a road shuttle of about 20 to 30 minutes. T2 and T3 are only around 500 metres apart and partly airside-linked, so some connecting passengers (for example, certain Air India connections) do not go landside to re-clear security. Delhi is also rolling out fuller airside transfers across T1, T2 and T3, expected by the end of 2026, per Business Today. Our Delhi terminal guide maps which airlines use which building.
Bengaluru (BLR)
Bengaluru’s T1 (domestic) and T2 (international) are linked by a short free shuttle that runs roughly every 10 to 15 minutes, a few minutes’ ride, per the BLR transit page. Around 3 hours is a sensible buffer for domestic to international. International to domestic, with baggage reclaim and recheck, more often wants 3 to 4 hours. Note that some Air India domestic flights also operate from T2, which can avoid a building change. No official “published MCT in minutes” was found for BLR, so treat these as practical guidance.
Hyderabad (RGIA)
Hyderabad uses a single integrated terminal for both domestic and international flights, which makes transfers materially quicker than at split-terminal hubs, per Hyderabad Airport. A dedicated transfer desk assists connecting passengers. The airport lists 45 minutes as the domestic-to-domestic minimum connecting time only; an international-to-domestic transfer still needs immigration, baggage collection, customs and recheck, so budget more.
One ticket vs self-transfer: where does your protection end?
This is the single most important distinction for connections, and it decides who pays when things go wrong. On one ticket (a single PNR), MCT applies and the airline must help you if you misconnect. On separate tickets, a self-transfer, there is no MCT protection and no automatic re-accommodation, per Kiwi.com.
On a self-transfer, the second carrier owes you nothing if the first runs late. You buy a new ticket, pay for any hotel yourself, and you must reclaim and re-check your bags, clear immigration and re-clear security between flights. The cheaper “hacker fare” can get expensive fast.
Through-checked bags are part of this. On a very tight but legal connection, checked bags miss the transfer more often than the passenger does, per The Points Guy. On one ticket the airline must forward a delayed bag to you; on a self-transfer, that is your problem to reclaim and re-check.
Whether your bags get tagged all the way through often depends on how the airlines are linked. Our explainer on codeshare versus interline flights covers when one ticket really does mean through-checked luggage.
What does Indian law cover if you miss a connection?
India follows DGCA rules, not EU261 or US DOT, so the remedies are different. There’s no EU-style flat payout and no US-style tarmac rule for connections here, per the MoCA Passenger Charter. Relief for a missed connection comes from same-ticket re-accommodation and compensation, and it applies only when your flights are on one ticket number.
The relevant rule is DGCA CAR Section 3, Series M, Part IV, which covers a passenger who missed a connecting flight booked on the same ticket number. The airline must offer an acceptable alternate flight, or compensation plus a full refund. When the misconnection is caused by the airline’s cancellation, compensation is tiered by block time, per the Vikaspedia consumer guide.
| Block time of alternate flight | Compensation (or basic fare + fuel, whichever is less) |
|---|---|
| Up to 1 hour | Rs 5,000 |
| More than 1 hour to 2 hours | Rs 7,500 |
| More than 2 hours | Rs 10,000 |
Two big caveats. There’s no compensation in extraordinary circumstances beyond the airline’s control, such as severe weather. And none of this applies to a self-transfer on separate tickets, because there is no single ticket number to protect. For the full step-by-step, see our missed connecting flight guide and the HappyFares missed-connection help page. DGCA’s wider delay and cancellation rights are covered in our flight delay compensation explainer.
Common Questions
Is 45 minutes enough for a connection in India?
It depends entirely on the airport and connection type. Hyderabad lists 45 minutes as its domestic-to-domestic minimum at a single integrated terminal. At split-terminal hubs like Mumbai or Delhi, or for any international transfer, 45 minutes is usually too tight once you factor in terminal changes, security and boarding cut-offs. Confirm with your airline.
Can I book a connection shorter than the minimum connection time?
Not on a single ticket. The booking system will not sell a same-ticket connection below the airport’s published MCT, so anything you can buy on one PNR is technically legal. You can create a shorter gap only by booking two separate tickets yourself, which removes all MCT protection and re-accommodation if you misconnect.
What happens to my checked bag on a very tight connection?
On a tight but legal connection, bags miss the transfer more often than passengers do. On one ticket, the airline must forward a delayed bag to your destination. On a self-transfer with separate tickets, you have to reclaim the bag, re-check it and clear security yourself between flights, so build in extra time.
Does DGCA pay compensation for every missed connection?
No. The Rs 5,000, Rs 7,500 and Rs 10,000 tiers apply specifically when a same-ticket connection is missed because the airline cancelled a flight, and the amount is capped at basic fare plus fuel if that is lower. There’s no compensation in extraordinary circumstances beyond the airline’s control, and none at all on separate-ticket self-transfers.
How much time should I leave between flights to be safe?
Aim above the bare minimum. Mumbai officially suggests about 2 to 3 hours for domestic and 3 to 4 hours for international connections. Bengaluru’s roughly 3-hour buffer suits domestic to international; international to domestic with bag reclaim often wants 3 to 4 hours. When in doubt, more cushion beats a missed flight.
Is a self-transfer worth the saving?
Sometimes, but only if you understand the risk. A self-transfer means separate tickets, no MCT floor and no airline re-accommodation if the first flight is late. You’d pay for a new ticket, any hotel and re-handle your own bags. It can work with a generous, deliberate buffer, but it is not protected the way a single ticket is.
Booking a connection? Compare itineraries and see the full layover before you commit. Search flights on HappyFares to weigh fare against connection time, then pick the buffer that actually fits how you travel.
Disclaimer: Connection times, airport terminal layouts, fees and DGCA compensation rules are indicative and can change. Per-airport minutes here are planning guidance, not guarantees, except where attributed to the airport. Always confirm current details with your airline, the airport or DGCA before relying on them.
