Flew LHR - YUL recently was on a 241 redemption in Y as no availability elsewhere (don’t worry, return was from JFK on 747 UD)

I had had a greeting from a lovely member of crew before take off and thought that was all done and dusted and was happy with my bottle of water and an empty middle seat between myself and my lady.

Then - shortly after take off, another (more senior) crew member came and said hello and that there was space in WTP for myself and my partner if we would like.,.

Well yes we did like!

Thanks to BA’s excellent crew on this occasion, was very very much appreciated!

We actually got engaged on the trip and on the return from JFK one of the crew ran round unbeknownst to us before take off and got a nice card signed by all the crew. Presented to us with an amenity kit from F for each of us.

All in all, great trip both ways.
