Just an update on seat selection.
As they had advised me, the selection now goes live 90 days ahead of your return flight both on-line and by phone, so there is no longer the difference. The downside of the new policy for those staying 14 nights is that those customers who are holidaying for 7 or 10 nights get to choose the outbound seats before you can.
We signed-in on the morning of the first day we were allowed and got exactly the seats we wanted for the return flight but had to settle for others on the outbound.
So the advantage against last year is the web selection opening at 90 days but the disadvantage is that it is 90 days from the return, not the outbound.
