My bad, ignore the above. In fact two of the flights from Sunday did not post. Because I went to NCL and back twice on 19 Nov (on 4 different E-tickets and 4 different locators) the BA Exec Club said even with the different ticket numbers their system usually sees itself as awarding dupe points for one booking if it sees the same route twice and therefore only posts one booking. He's seen it before. Therefore, the missing trip will have to be added manually, taking up to 14 days.
