Seat selection is usually possible, though how and when depends on the airline. Some let you choose a seat during booking, some charge for preferred seats, and others assign seats automatically unless you pay to pick. The option that applies to your flight is shown as you book.
If sitting together matters, for example when travelling with children, it is worth sorting the seats as early as you can, because good pairs of seats go quickly. Leaving it to check in can mean taking whatever is left.
Where seat selection is not offered at the time of booking, you can often do it later through the airline directly using your booking details. If you are unsure how to go about it for your particular flight, our team can point you to the right place so you are not left guessing at the gate.
