Three questions:

1) Trying to figure out what booking class a BA Holiday (“vacation” according to the US website) from JFK-LON-JFK would book into in World Traveler Economy.

Old threads here suggested G class but I see in the ticketing restrictions that the ticket looks completely flexible which would be unusual for such a low booking class fare. Any ideas? Trying to figure out how many TP the double tier pints will actually be if I book this. Lowest fare classes would be 20TP usually each way but flexible Y is 70TP usually so that’s a big difference.

2) Can one stack an AARP discount with a BA Holiday booking?

3) Also: can one check into the hotel and then not actually stay there, except for reappearing, if necessary, to “check out” on the last day? Don’t need the hotel except for the points but I know the USA holidays T&C are different from the UK ones and things have got stricter since this started.
