Trying to make a FF airline decision
 

I'm sort at the crossroads here as I am sure many of us are. I currently have 88K miles on AA, 46K on US, 4K on NW,1k on DL. I used US exclusive last year and switched to AA this year. I am based out of PHL so yes US goes everywhere I need to go. I fly about twice a month domestic only. I would like to stay with US because they have the most non stops but I am afraid that I may lose the miles if they go into BK and liquidate. I doubt AA will liquidate but they most likely will go into BK. I could always just transfer all of my miles from AA to HH program and be done with them. The thing I don't like about AA is they are never on time and I almost always miss my connection if I am going thru ORD or DFW. So my question to all of you is (without saying Southwest), what would be my safest bet ? Fly US and be on tome but worry about my miles, Fly AA and be mad at being late all of time, Switch to Delta/NW since they might be one of the survivors ? Any and all comments are appreciated.

What you got against WN? (see, didn't "say" it!)

They don't go everywhere I need to go on the short hauls and their FF program is not as good when taking a long haul.

Just credit to any airlines FFP (e.g. BA, AF, LH) which is NOT American since they are not likely to go BK.
