To get the best airline seats, use seat comparison charts on a site such as SeatGuru.com to compare different airlines' seat dimensions. Identify the best seats on the plane's seating plan on SeatGuru.com or SeatMaestro.com, and select the seats during online booking. Book early to get the best seats.
Confirm the seat selection a few days before flying in case the airline has switched the aircraft type. If your preferred seats are not available, check in online to see whether exit rows and bulkhead seats are available for booking, as some airlines do not release these until the days of the flights. Check again at the gate in case any passengers who have booked preferred seats have been upgraded to business or first class seating, leaving their original seats vacant.
