I just want to see if anyone else has any experience with this: Scenario (which actually happened): Was supposed to fly PEK-ORD-JFK, spend a day in New York, then get on a LAN flight to Buenos Aires (ticketed separately). A "fuel leak" on the AA flight in PEK resulted in a flight cancellation, so AA immediately rebooked me on UA for PEK-SFO-JFK since I was flying business. Long story short... I missed my flight to Buenos Aires. LAN absolutely refused to put me on the next flight (no status on LAN, was flying economy) and would only tell me to deal with AA since it was technically AA's fault. My point: After hours of talking with AA reps (22+ total...), finally got a manager on the phone who told me that most agents don't know it, but as a OneWorld partner, AA is responsible for getting me to my final OneWorld destination if they were at fault for my missed flight. He also proceeded to book me (no charge) on AA metal rather than LAN. Don't know if any of you have had experience with this, but do you know if this is official policy? I would hope it is considering it's an alliance, but most of the agents I spoke with simply refused to help since I had two separately booked tickets on two different airlines. Maybe most agents were just too lazy to figure out how to process my (rare) issue... or it was a courtesy.
