have a flight booked for tomorrow at 15.00 which l wish to change. Paid 80, new fare is 100 as shown on screen but when l click on to where it says calculate new price it comes up at a much larger amount than the difference between old and required fare plus 25
all these amounts are sterling, anyone else had probs, l have ticked the box to indicate it was a flight change, looks like l am going to lose out big time on this[
