Just landed on the 178 from JFK and noticed before I left that BA2 was delayed until 2130.
I asked and was told the air con had failed and therefore the plane was U/S. It was expected to be back in the UK at 7am.
Needless to say, there were a few very peed off passengers who had to go on the 178 and my upgrade to WT+ was cancelled to allow for some of the upset passengers.
The flight time for 178 was only 5 hours 29 mins tonight so it only took 2 hours extra on our blunty.
FYI, the failed aircraft was G-BOAC
