Family is looking into US to FRA flight and find r/t fare on UA at around $ 1,600.00 p.p. Booking on UAV, incl. throwaway hotel, brings it down to $ 797.00 ea, quite a difference. Trying to educate me though this thread. They are not worried about lack of credits, mile or otherwise. Seating is the point of contention. On the UAV generated seatmaps all E+ seating incl. exit rows are blocked ( everything is wide open on the UA seatmap ). They are all 1K. Is it a given that after booking with UAV that the reservation will show under their UA MP account and then the seatmap will show ( as it does now on UA ) with the possibility of choosing E+ and/or exit row seats? Or does a UAV bulk fare precludes them from choosing seats in the front of the Y cabin?
