Last June I was able to book an off peak Biz Class tix EWR-CLT-CDG for 60,000 miles for travel in early Feb 2012. I now have a new job and will not be able to take this trip. I am a 'nothing' on US, and read that there is a $150 redeposit fee. I also saw that if there were changes made by the airline to my reservation, the fee might be waived ? Last week I received a notice from US changing very slightly my flight times (by 10-15 minutes for each flight). Now normally I wouldn't have had a problem with these changes, but could I use those changes to cancel without penalty ? Or do I need a more legitimate excuse ??
