Can I select my seat when I book and buy my ticket via EVA Mobile?

Yes, If you already purchased the ticket via EVA Mobile and your flights are with EVA Air, you can select your seat using the Mobile App up until 24 hours before departure. Passengers who have used our advance seat selection service are requested to complete check-in procedures at least one hour before their flight is scheduled to depart. EVA Air and UNI Air may adjust seating arrangements when there is an aircraft type change or to cope with other operational requirements.
