OK, I posted this in the Newbie thread last week, and have searched and perused all of these forums as well as the AA and BA web sites, but still am having a hard time getting insight and answers, so here goes -- and thanks very much in advance for all your assistance.

I'm planning a trip to Europe next summer for a long-lost family reunion, using miles so planning early. There's a good chance we'll be flying with a lap infant, about 2-3 months old. Likely routing will be from DFW through LHR, then on to places on the continent.

My general questions are:

(1) What is the better airline/class to fly? I know BA almost always wins hands-down over AA, but not sure what the airlines' policies are regarding lap infants in F or J. Any particular restrictions with infants flying in the front cabins? Are bassinettes generally available or not available in certain classes?

(2) I'm trying to make sense of the airlines' pricing policy for infants on trans-atlantic flights. It looks to me like AA charges 10% of the adult fare for a lap infant on these flights, but what is that 10% based on? And does BA charge a similar fare? If my wife and I are traveling on award tickets, I'm assuming we'll still have to pay for our lap infant.

Again, many thanks for your help!
