Well, I admit that for some reason I'm a little more nervous about my flight across the Atlantic this time. I've usually flown on 777's, but now I'm booked on a 763 (which I understand is the same as a 767-300) for my trip later this month. I booked it through British Airways, not knowing that it's actually an American Airlines plane. Isn't this a lot smaller - and is it okay for crossing the Atlantic? Experienced flyers, would you fly on this aircraft? Thanks for any help in easing my unusual anxiety.
