My wish list:
1) Allows change of FFP for mileage acrual after online check-in. BA OLCI allows it.
2) Displays and allows booking by class code.
3) Allows 24 hours hold so that you could call CX for ticketing. Maybe you need to use a voucher!
4) Allows open return booking for classes which are eligible.
Yeah! It is a lot to ask for, but we could all wish.
