Troubleshooting

'Auto Check-in failed' - This can happen if there is a significant flight delay or cancellation; proceed to standard check-in. 3. 'Cannot select seat' - Seat selection closes 3 hours before departure; seats are assigned automatically at check-in. 4. 'Booking not found' - Ensure you are using the correct 6-character booking reference.
