The 1424 was cancelled on Friday. I was switched to the 1430 and waited in the lounge with the board indicating a Gate 8 departure. There were no other planes waiting there. So yet again it bemused me why at the last minute they switch the 1430, which was an incoming Dublin flight, to gate 77 and we all have to trek down the green mile. I spoke to a BA staff member last weekend about these switches and she volunteered that these switches bemuse the BA staff too, particularly as Virgin have long since departed to T2.
