I have flown a few sectors in CE with BA, although only in the single digits, so I am a bit of a newbie and no where near as experienced as some of the honourable members above!
I did an upgrade EDI-LHR on the 767 on Friday and I have to admit I was really impressed, the crew did a fantastic job. There was only 10 in the CE cabin so not taxing for the two crew members working up front, but even for such a cheap upgrade I was kept toped up with Champers, given a bottle to take off with me, and then allowed to have a quick look in the cockpit!
