Hi again,
If you colectr miles I would say $96 is worth it for 8k. Also AA will give yiu the largest seat pitch out of any of the options. I wouldn't worry too much about IB as this will only be a short hop in the EU correct?
I can't believe you cant't find any info on BA. There are loads of reports on it on this sight. under FT MILES and reports on airlinequality.com epinions.com etc.
I think you will like BA for the IFE and service but the seat pitch is a lot worse than AA. All food is much of a muchness in coach and not worth being a factor in your choice.
If I had to fly coach then I would take the AA/IB option. Its only a few hours out of your life anyway.
