Hello everyone,

Back in September I booked a cheap trip (£320) to BOS in April using the World Cup discount code which brought it down to £260, but time pressures have meant I had already been mulling over cancelling this trip.

If I were to simply cancel, I know I'd get something back - but is there an easy way to work out how much would that be? The ticketing email says "government, authority and airport charges" were just over £170, and "BA fees/surcharges" just under £140. But obviously that's prior to the discount voucher, which complicates the calculation!

But... I also received an email notification of cancellation of the return BOS flight yesterday, which prompted me to check FT about what rights I have in this situation. As I understand it, if the time change to the auto-rebooked flight is >2 hours I would have the option of cancellation with full refund; if less than this I would be able to request rebooking to another flight on the same date (in the same cabin etc). In this case, it is less than 2 hours: BA214 (departing BOS 22:50) is cancelled and I've been rebooked to BA202 (21:40).

However, when I searched for that email, I realised I'd already received another cancellation in December for the same return trip from BOS: namely, my onward (dep LHR 13:20 the following day) was cancelled and I had been rebooked to one departing LHR 14:25. If I do nothing, my overall journey time is now >2 hours longer than when I booked it - starting an hour earlier, getting in to my destination an hour later - because of the two cancellations/rebookings.

This leads to two linked questions - the answers to which which may be useful to others - that previous threads haven't thrown light on:

a) Is there a time limit for exercising one's rights after a cancellation? i.e. regardless of whether it's greater or less than 2 hours, how long does one have to contact BA to discuss options - in my case, the first cancellation was in December.

b) What happens where there has been > 1 cancellation in the same trip, in a situation like mine? Do one's rights change in any way? Does this in turn change if the total changes exceed 2 hours?

Finally, in my specific case, what options do I have, and how long do I have to exercise those options? Would I be able to get a full refund given the circumstances? Or ask for a change of date (in my case to make the trip several days shorter, or to postpone it say 6 months)? I was more or less resigned to only getting some of the fees back if I cancel, so any improvement on this is a definite bonus.

Sorry for the amateur questions - this is the first time I've ever been in a situation like this.
