Same question, but around the timezone of year end. I think I will be departing on Mar 8 (my year end) next year, but on PST (SFO->LHR). At the time of the flight in question, it is Mar 9 in GMT in the UK. Which year will the flight post in? (I'm aware of the provisions to extend the TP year, but (a) the TP level in question is for CCR renewal for which I don't think they will extend the TP year, and (b) the situation might well be the other way around, i.e. I've already passed the threshold and want it to fall into the next year)
