Looking for advice. I am a UA 1K. My new weekly route is FAT (home) to SEA (work)round trip for about the next 6 to 12 months. United routing is not as convenient or cost effective as Alaska Air. I researched Alaska's code share partners and I found American and Delta both code share with Alaska. I want to apply for a Status match on either Alaska, AA, or Delta, is there one that would be better to do than any other? Will the AA and US Air affect anything? What would you do?
