Hello - My wife and I booked Oneworld first class award tickets a few months ago. I was looking at the reservation randomly the other day to find out that our last leg flight was canceled. US Airways put us on a flight but it leaves before my international flight arrives. Early September HND-SFO to arrive at 17:45. They put us on a US Airways flight that leaves at 17:05 from SFO-PHX. I checked and there is no later flights on AA or US Airways. I booked a SWA flight SFO-PHX for back up, but want some ideas and or recourse for US Airways since now I have to pay for that last leg (let alone its not first class). Since were not traveling until September I hope something else opens up.....
