How do the two airlines compare in transatlantic business class? I don't need information on Virgin or Singapore - which may be better but which don't accept my frequent flier miles!

I don't know how United is. I flew American business class from Ohare to London last month. FABULOUS!!!

Thanks for the information JZ. I'll also be flying from ORD to LHR. I've recently been on United's Business class to Asia and thought it was wonderful. American sounds good too.

I haven't flown transatlantic business class on United, but have on both American and Delta. Overall, American is the best in my opinion. Generally the food is a bit better and seats seem a little more comfortable. The wine choices are better on Delta however. Either is so far superior to coach that I will never fly transatlantic coach again!

Alas, I am coming back from Europe on Iberia in coach. But I figure it's a day flight so I won't have to sleep and I can get up alot out of my cramped seat and walk around. Iberia will not allow me to use AA miles to upgrade to coach. I could have flown from Madrid to London, then returned business class on American but it would have added 4 hours to my travel time. At least I'll be business class on the night flight from Chicago to London
