Just ended up booking F from DFW-LHR for 3 people on BA. The YQ was $347, which is fine with me. Two of the people I travel with are very obese and J or F is our only option...and getting three seats on an AA Saaver award is near impossible (we don't have flexibility).
It's still cheaper than buying an econ ticket (even moreso for the one companion who would need 2 tix).
The only way I could get AA to pop up was to limit it to 1 person and that just wasn't going to work for our plans.
