Title sums it up. I'm wondering if there's any issue with CO's system that "pushes" status over to other star carriers. On Monday, my MHT-DCA flight showed up as "Star Gold" on my BP on the US Airways flight with my CO number as FFD. Checked in today (in First class), and notices it now doesn't print "Star Gold". I thought this was odd. So for fun, I went in to the USAirways reservation and changed it to UA and told it to print my BP. Surprise surprise, UA number works fine and it now prints "STAR GOLD" on my boarding pass. What's going on here? Since I've flown several US flights in the past with my CO # and "Star Gold" I have to believe there is a issue with CO's system? My name format matches (I do have a "JR" in my name) between CO and the US reservation so I'm baffled why this is messed up. I've been reading all sorts of issues on Flyertalk about upgrade lists not working, FF status showing up wrong, etc. I've been on the CO side of things for a long while, but these issues are getting me worried for when they merge the systems together. This is frustrating. I hope my first segment at least posts on CO account. I went back and put in my CO number in and printed the BP again (of course no "Star Gold") as I'd like the miles to accrue on my CO account (which will replace the UA number anyway). I "may" go and put the UA one back in -- but then I'll probably get the outbound posting to CO and return posting to UA (which may not be horrible) but still it is a pain. Is it wrong for me to expect my CO Star Gold status which worked fine on Monday to also work fine on my Wednesday flight? Frustrating. I get the fact that merging these systems is a big task but if things are breaking that used to be fine and working, that really worries me. Has anyone seen this issue?
