Thanks for the reference to ExpertFlyer. I am still wondering why when I did my attempt at a One-Way, full fare Biz from BKK to NRT it only returned Coach availability when the seat map for the flight showed many empty seats.
Would EF show otherwise?
I have a printout of my Itinerary, showing 5 legs. The 3 legs I am confirmed BE as a Z with seats assigned but the BKK-NRT leg has two entries, one in Coach with seat assigned and one in BE with "Waitlist". The Delta agent told me as long as there is an empty seat in Biz I will get it. I wonder if he could see if there was anyone ahead of me on that list?
