I have booked a flight, but never received the confirmation email.
Thank God I inserted my AY FFP number (my exile after Tiermagaddon). In the AY mobile app the booking showed up immediately, and with the booking reference I could use the AY website and obtain a ticket receipt.
Isn't it pathetic to have to use Finnair's digital channels to get information on a British Airways flight that I booked with British Airways? Don't they feel ashamed at BA?
