While trying to book standard reward travel from CLE to AUA, I select dates and flights that show availability, but when I get to the end of the process, I get a screen that says "These flights are no longer available, please modify your search", Why would the "select" button be available when the flight isn't?
The same flights keep comming up daily, so it doesn't seem to be a case of just getting beat out by someone else while doing the booking process.
