Once boarded I settled in and the FA brought me a glass of water - yes, I did mean a glass. The glasses were collected before departing. The pilot did come on the PA to announce we were having a delayed departure due to a sick passenger, but that we would make up the time in the air. Hello, I want sleep, take your time! After take off I set myself up for sleeping. I put down my foot stool and put my seat in the lay flat position. I will say it's not terribly comfortable - the foot stool doesn't line up quite right, and the seat does have a stiff seat feel - it was not soft like a bed would be. I suspect the difference between first and business class is the width and length of the seat and the comfort of the seat/bed. Ahhh, I guess I was complaining again. I don't mean to because the lay flat seat was FANTASTIC, but I don't want anyone thinking that the seat is comfortable like a bed. But shortly after laying down I was out cold. I slept a solid 4 hours, I did sleep through dinner though to do that.
I woke up around the time that breakfast was served, which was good, but not great. A smoothie, fruit and a gross bacon roll. And of course tea, after all it is British Airways.
After landing I got delayed by having to repack the few items I had taken out of my bag and the passengers in "steerage" got off the plane ahead of me. I was appropriately disgusted as someone who was never in a class above economy and isn't counting on every being in a class above economy again. But I was able to go to an express line that's for First and Business class passengers so it didn't take too long to get into England.
After the flight I certainly saw the value in upgrading to business and first class, I did sleep very well. Is it worth the money and the points for it? At the time I thought, maybe. Then I heard the horror stories of the other people on my tour who flew in Economy and I really think I need a better job so I can afford to pay and guarantee flying in the better classes!
