Look at the facts. CO rated best US carrier across the Atlantic by JDPowers, Fortune Mag.
I feel the CO B777 is very comfortable in back with the 3-3-3 seating as opposed to DL, and AA's (2-5-2) .
We do LGW-EWR twice a day. With the 11:15am flight being the triple7.
And question for AA737. Young man how many times have you crossed the Atlantic on a AA flight?
I've crossed it twice on DL, Virgin once, Alitalia twice, and CO, over a hundred times, both flying, and riding.
