Swiss Air have come back to me saying that the ElAl Reference can only be obtained between 48 and 24 hours before the flight! I find that hard to believe. Almost every flight I book, and there are many, has the option of paying for a seat at any time after the booking by accessing the Manage My Booking option.
I will now ask a different question.
For a regular booking direct with ElAl have you the option of choosing your seat, paid or otherwise and can you go into the booking afterwards to then choose a seat?
Thanks
