here's a doozy...
i was looking to book a domestic UA ticket for same-day travel on 7/30. it was 8pm MDT, flight at 11:59.
TK website was useless as usual, so i called to get it done.
interestingly, the agent said it was already 7/31 where he is (presumably Turkey), and the system wasn't letting him search 7/30. called back and got the same response.
West Coast ticketing offices had also closed by then, so calling them wouldn't have worked.
i realized this might not be a unique conundrum, but also apply to other airlines with weak, dysfunctional websites similar to TK.
any workaround for this system quirk?
