Why are you doing it so often? Why don't you buy a flexible return ticket?
The travel plans last year has been like crazy. So had to do it
Couple of times. I had a fra-las in cw booked via aa and I ended up
In Bom instead of Stoke. Aa wanted 2000 pounds for change of
Date for 1400 pounds rtn flight. And ba had as mentioned one way
Fare.
