It looks like Fiance and I will be going to a wedding in Carmel, CA and leaving from there for a week in Switzerland and Northern Italy. A 1K friend has offered us some SWUs that he's not going to use before they expire in August. I'm a 1P, and Fiance has no status. Clearly, I understand that an upgrade has many variables on any flight on any given day, but we would really like to give ourselves the best shot to fly C across the pond. I was hoping that some Milepointers could give me an idea of which flight would give us the best chance at an upgrade (preferably ahead of time). Here are the transatlantic flights we're considering (Note: I have made sure that all fights are in an upgradable fare class.) All of these flights depart on Sunday, August 28: SFO-LHR - UA 954 12:50PM 777 SFO-FRA - UA 900 1:59PM 744 (I've still never flown on the upper deck of a 747) SFO-FRA - LH455 2:20PM 380 (About $100 more) IAD-ZRH - UA936 6:02PM 763 (booked on CO but operated by UA) SFO-FRA - UA 926 7:08PM 777 SFO-LHR - UA 930 7:15PM 777 (Appears to be "new" 777) SFO-MUC - LH 459 9:05PM 340 LAX-MUC - LH 453 9:05PM 340 Returning, we're looking at the GVA-IAD nonstop on a 763. Thanks a lot for your advice!
