I have flown 500K miles lifetime on UA. Their prices have been very steep the past couple of years. I have pretty much switched most of my domestic flights to Southwest Airlines out of SFO/SJC with about 10 domestic trips each year. I fly SFO-HKG 2 to 3 times a year on Singapore Airlines (cheaper than UA) and once or twice a year SFO-NRT on UA. Will be moving to SEA area early next year. I did enjoy the domestic upgrades on UA before I switched, but not sure if I can justify the prices (especially on international upgradeable fares) or continue on to 1M miles for the lifetime 2P. I also like the *A international baggage allowances and lounge access. Any ideas on what I should do?
