Now done... because we're worth it.
Indeed, and thank you.
Hartington:
I suspect you will find that there is also a requirement that there are seats in the same fare bucket. If that is not the case (and with Orlando that feels a likelihood) you will have to pay not only the upgrade fee but also the additional fare to whichever fare bucket is available. The £70 doesn't guarantee you will be able to change it's simply a fee IF space is available.
Yep, thought this would be the case, in my case I would just change until there was space in the same fare bracket or pay for upgrade of cost of staying was much more. But my understanding was this the same would apply to a flexible ticket also - only flexible if available seats in the same class.
Although thinking further I think you may be saying about fare prices available at the time e.g. prices change for seats within the same class as the flight fills up..... perhaps I should give them a call to clarify.
