Date February 25, Gates closes 23:55, Departure 00:25
Underneath in bolder print yet it once more states BOARDING 23:55
We arrived at the airport on February 25 shortly after 9PM only to find out that we had missed our flight from the night before and were turned away. The flight was not fully booked but no effort was made to accommodate us. We were told to call the local office in the morning to make new arrangements. When being made aware that it should been stated that the gate closing time of 23:55 referred to a February 24 date, my argument was dismissed and we were left totally stranded as nobody was willing to do anything for us in the middle of the night.
We were able to get a new booking for February 27, purchased economy tickets this time and given the privilege of one extra suitcase as well as the use of the lounge in London Airport since we originally had business class tickets from London to Washington. Once we arrived in London, that privilege was also denied because they did not accept our old, unused boarding passes from two days prior.
I have written a letter to BA to make them aware of their responsibility in this particular case but only received a generic answer that did not address the issue of gate closing time not corresponding with the flight departure date.
