Went on a little shopping spree for myself in England and i purchased 3 suits (and an extra jacket). I'd rather not squash them into a suitcase but instead take them on board with me so they are hung on the rack.

I'm flying MAN - LHR with BA then LHR - LAX with AA in J.

​​​I figured BA might have more issues with this than AA with the smaller plane (hence why posting in BA forum) but I am leaving Sunday morning which is hardly peak business travel.

So.... How many is too many?
