I have just noticed that the flights are still posted for the following week, and indeed for a number of weeks with no particular rule as to when they fly them and when not.

If I wait a week or so and they are still posted, I may move the trip a week later, BUT will they then honour the 210 TPs for my babybus return to London, or will it be treated as a new booking and go down to 140? Should it remain at 210 if it is a change in an existing reservation with the PNR remaining the same?
