How Airport Connections Usually Work

Hub airports are built for connections. Thousands of passengers arrive on one flight and leave on another, often within an hour or two. The airport sets a minimum connection time, the shortest connection that airlines are allowed to sell on one ticket.

One ticket vs separate tickets

On a single booking the airline is responsible for getting you to your final destination. If your first flight is late and you miss the second, the airline normally rebooks you. Your checked bags are usually sent through to the final destination.

On separate tickets, each flight is its own contract. If the first is late, the second airline has no obligation to wait or rebook you. You may also need to collect and recheck bags.

Transfer security

Many airports require connecting passengers to go through security again. Liquids bought before the first flight may be confiscated unless they are in a sealed security bag. Duty free purchases are usually fine if sealed properly with the receipt inside.

Finding your next gate

Your onward gate may not be on your boarding pass yet. Look for the nearest departure screen once you're off the aircraft. Follow Transfer or Connections signs, not Arrivals.

Documents during transit

Some countries require a transit visa even if you never leave the airport. Others require it only if you change terminals or pass immigration. Check before you book, requirements can change and they depend on your nationality.

If you're running late

Tell the cabin crew before landing if your connection is very tight. They sometimes can arrange for you to leave the aircraft first or tell you the onward gate. Once inside the terminal, head straight to the transfer desk if you think you will miss it.
