(1) If it's a NEW AC operated flight, I'm back in the original cabin. If I change AC 123 - AC 456 to AC 123 - AC 789, I keep R on 123 but back in the original class on 789
(2) I'm being offered PY on SK when my original booking was Latitude, so it's not the original cabin
(3) That previous SK flight is the native flight number
