Don't apply with Barclay's. (US Airways, LH, Spirit, etc). They have 2 tier signup bonuses, one much lower than the other.
I have no problem with many banks (Citi, Chase, credit unions, etc) getting decent limits (10-20K) but I only got 3.2K limit w/US Airways Plat with 10K signup instead of 35K. Waste of my time.

I don't mind a lower limit if I got my full 35K signup bonus.
No more Barclay's for me.
