Any thoughts on AA 77W vs. BA 77W/772 Club Suites with doors (would be JFK->LHR).
AA Pros to me are (1) better arrivals lounge, and (2) advance seat assignment (I'm OW Ruby though *may* be able to confirm further out via corporate travel dept).
BA Pros are enhanced privacy with doors (I've never flown with doors but understand many see it as a gimmick).
In-flight catering not a consideration.

Other considerations - any feedback helpful

• I'm pretty sure AA has air vents, do BA planes? I'm often hot on an overnight and it can prevent good sleep. I do have a USB fan I can bring if needed.
• AA has the Casper bedding I think. What does BA offer? (E.g., AF's bedding was notably worse than DL, so wondering how this compares).
• AA's Cirrus seats are very good for sleeping; I have less experience with the underlying SuperDiamond seats that I think BA uses. Main concern is about footwell and shoulder size/space.

I will most likely stick with BA CS on the return for better in-flight catering despite better T3 lounges, but open to be swayed...
