Something innovative would be to waive the change fee for top flyers. Perhaps the fee would be waived if the flyer changed res online, and reduced if they do it through res. Also allowing upgrade on award tickets....NW does this. Also no capacity controls on awards....WN does this and SPG. I confess I don't know anything about Jet Blue, so cannot comment on how these changes would match its business model or other innovation. Do they even have F class?
