- Lufthansa generally opens first class award seats to their partners only within 14 days of travel.
- Their Los Angeles and San Francisco – Frankfurt flights are among the toughest to get, even then.
- Both flights are operated by an Airbus A380.
- And most days currently have 2 first class award seats open from late November through March (which is as far out as the schedule currently goes).
You can book with United miles, partner first class Europe awards are certainly expensive (you can also book Asia via Europe .. such as US – Frankfurt on Lufthansa and Frankfurt – Seoul on Asiana or Frankfurt – Bangkok on Thai). United gets 110,000 miles each way for partner first class to Europe.
You can book with Aeroplan miles, Aeroplan is an American Express Membership Rewards transfer partner and points transfer instantaneously — for 62,500 miles each way. You’ll pay fuel surcharges, though.
