I'm Chairman's Preferred, but I'm switching to another airline to stay on the Star Alliance the second the changeover occurs in March.  I'm tired of US Airways' cattle cars with no services except wifi.  You don't even give power outlets to first class travelers.  That's absurd.

I'm tired of being told ludicrous explanations that my flight from SFO to Zurich is "direct," despite stopping in PHL, changing planes and likely having to switch terminals.  I'm tired of flying in outdated 767s that leak water on me.  I'm tired of your flight attendants' attitudes, that when I point out the water leaking on me from the water-damaged internal fuselage, tells me there's nothing they can do about it instead of WRITING IT DOWN SO A MAINTENANCE PERSON CAN FIX IT.  I'm tired of complaining about poor service and having another flight attendant complain back at me that they lost their personal closets in the latest plane overhauls, as if I should care about that.  I'm tired of not having a personal movie system in economy
