Is 3 hours enough for self transfer?

Factor in a minimum three-hour window when flying to high traffic airports or traveling during peak days or hours. It's also important to know if you have to exit your terminal, collect your bags, and go through security again. If so, it's best to add another hour cushion for self-transfer flights.



A 3-hour window for a "self-transfer" (where you book two separate tickets on different airlines) is generally considered high-risk and is only recommended if everything goes perfectly. During a self-transfer, you must deplane from your first flight, clear immigration (if international), wait for and collect your checked luggage, move to the departures hall, check in again at the new airline's counter, and pass through security. Most airline check-in counters close strictly 60 minutes before departure, meaning you actually only have 2 hours to complete all the arrival and transit steps. If your first flight is delayed by even 45 minutes, or if the baggage carousel is slow, you could easily miss your connection. Because the two flights are not linked, the second airline is under no obligation to rebook you for free if you arrive late. In 2026, travel experts suggest a minimum of 4 to 5 hours for self-transfers at large, busy hubs like London Heathrow, Dubai, or New York JFK to account for potential delays and the physical distance between terminals.

The rule of thumb is that you leave AT LEAST 3 hours from arrival to departure for international flights and 1.5 hours for domestic. You still have to get your bags, clear customs, re-check your bags and then go through security for your next flight. All of this can take a couple of hours.

It's doable, but there is a very good chance it will take a min of twenty mins from landing to disembarking. You need to be at the gate 20 mins before departure of the next flight, normally, so you have twenty mins to clear security and get to the next terminal. Personally I would not chance it. It's very very tight.

In most cases, a 30-minute layover for domestic flights and an hour for international flights is considered a minimum, or short, layover.

If your itinerary was purchased as one ticket (as in: you have only one itinerary and one confirmation number), and the connection time was too short and you miss the second (or third) flight, you can rest easy, no matter what happens. The airline will simply put you onto the next available flight, free of charge.

Travel advisers say there's a lot to take into account when booking connecting flights, but a general rule of thumb is 60-90 minutes between domestic flights and at least two to three hours for international itineraries.

While, generally, the airline won't wait for connecting passengers, there might be some exceptions. If a flight is delayed, and there are many passengers who are connecting from this delayed flight onto the same connecting flight, the airline will hold the connecting flight for these passengers.

For domestic connections within countries like the USA or Canada, a general rule of thumb is to have at least a 60-minute layover. However, at large airports like Atlanta or Toronto, you might want to consider longer connection times to account for the airport layout and possible security checks.

In a passenger context, MCT is defined as the shortest time interval required in order to transfer a passenger and his luggage from one flight to a connecting flight, in a specific location or metropolitan area.

Most (but again, not all) airports connect international terminals airside. When you're connecting from an international flight to a domestic one, you'll always have to exit and reenter security as you'll need to go through customs and immigration (unless you have gone through preclearance aboard, which is rare).

In most cases, airlines recommend allowing at least two hours between connecting flights to ensure that you have plenty of time to make your connection.

If you miss your connection booked with the same airline that your were on for your first flight, and the issue is due to a delayed take off or anything else that's in the hands of your airline, it's the airline's responsibility to rebook you on the next available flight.

MORE DETAILS

Most airlines define a layover as any connection of less than 4 hours on a domestic flight or less than 24 hours on an international flight. Rules about when stopovers are allowed varies by airline, and it will often depend on whether the ticket is an award ticket or a paid ticket.

MORE DETAILS

Depending on the airline, travelers may be charged a rebooking fee to get on another flight. Some airlines may also charge the difference in airfare — meaning a missed flight can be a costly inconvenience.

Do connecting flights wait for delayed passengers? Most airlines will try to accommodate passengers from a delayed inbound flight, but it's not guaranteed. Flight attendants might notify the ground crew of connecting passengers, but airlines typically won't delay a departure for a small group.

Allowing yourself at least a 60-minute layover for domestic flights and a two-hour layover time for international flights can often be a much more comfortable and stress-free journey than booking a flight with a very tight connection.

What is an MCT and who controls it? An MCT is set by the airports (not airlines) and is considered to be the minimum amount of time required to transfer from an incoming flight to another flight (international or domestic) by an able-bodied person given the circumstances involved in that transfer.

Pilots and cabin crew's time at work is strictly regulated to minimize fatigue and increase safety. As such, a flight may not be held for delayed connecting passengers if to delay it would push employees too close to their hours limit.
