According to what I hear from the Denver media, F9 is actually gaining seat-miles flown, at least from the last report I saw. Reading between the lines from the quotes made by F9 media contacts, if WN is living off of the business missing from F9, they are not doing well! It looks like WN is gaining flyers from UA.
Things must look alot different concerning F9 when seen from here in Denver rather than as seen from other parts of the US. The feeling in general here is that there are still many, many loyal F9 flyers, and that F9 will turn out to be just fine, or to say it another way, if UA could get out of Chapter 11, F9 will too!
