A: Airlines limit the number of seats that can be reserved in advance for reasons such as securing seats for passengers who require special assistance when boarding and for adjustments to the balance of the aircraft.

Hence, in the event that there is no display of seats that can be reserved, or seats for a certain number of persons are not displayed, kindly try again a day or two later, or make the seat selection during the check-in process.
* Seats are subject to availability depending on check-in time

Please be assured that even if seats have not been selected in advance, the airline(s) will have seats assigned for all passengers at the time of boarding.
