Shoulda dropped me a line! I have flown UK-US approx 10 times in the T7
with United, in all classes and found them to be very good.
Economy service is efficient. The seats are fairly comfortable (and an inch wider AFAIR than the 747) and have the seat back TV
. Programming is not fantastic, but there should be a couple of movies that appeal and can make the trip pass a little quicker. Channel 9 is obviously pretty good fun, and take heed of the tip above about your own headphones! Meals aren't bad, though I usually go for the low-fat stuff now as I don't think it is always particularly healthy, particularly the snack pre-landing which is (was) crisps, cheese ham and egg bagel and chocolate, but its nice to have a choice.
Legroom is a little limited, but I like the 2-5-2 in Economy.
EconomyPlus is nice if you can get it.. go for the last row of EconPlus if you can, so you can sit back in comfort without "recliners remorse!"
Which class are you travelling in?
Business is nice... not the flat beds, but I prefer it over BA
Or are you going First Class? (you flash git!)
