Just when I thought I have seen every underhanded trick that the airline industry uses, ANA has come up with a new one. We are a family of four and we booked round trip tickets from Tampa to Tokyo via LAX. We booked the flights via AMEX; the domestic leg was United and ANA was the international leg. We booked our seats on the domestic leg via United, but they informed us that we would have to reserve seats on the LAX-Tokyo leg directly via ANA (which is not unusual). When we went to the ANA website, it was only showing middle seats available (no aisles, no windows), which was dubious because the flight was six months away. So, we called ANA directly and they informed us that THE FARE THAT WE BOOKED VIA UNITED WAS ONLY VALID FOR MIDDLE SEATS. We have travelled to over 40 countries on five continents and have NEVER encountered this trick. We asked how much more it would cost to get out of middle seats, they said it was $900 PER PERSON. Fortunately, we had a long layover in LAX on the way to Tokyo and the gate agent there took pity on us and switched our seats to four in the same row for no charge (the flight was not entirely full). But, that does not change the fact that ANA tried to extort $3,600 from us for seat assignments that should have been free. Avoid this airline at all costs.
