A relative (no status) booked a return Y flight SYD-LAX with Virgin. During the booking, she tried to select seat for the return flight 3 months away, and most / all window and aisle seats were crossed out (not available) - available seats were middle seats
Not sure if the window and aisle seats were blocked or occupied?
Question: When does Virgin release seats for better selection for international flights? For example, QF open the seat map at T-80 for domestic flights (not sure about international flights). Also know that Eva Air allows checkin 48 hours before departure when pax (with no status) can select some better seats. Does Virgin have this choice?
Thanks in advance.
