I really enjoy flying F9 but agree their website is a dinosaur... even when they "redid" it several years back, they just put a new skin over the same old booking engine... the colors and graphics changed but the old website functionality was the same.
I hear they're coming out with Tiered pricing and major changes to EarlyReturns pretty soon, and that it was delayed primarily by technological reasons. I wonder if this means that they are writing a new website (along with the back-end system changes which would obviously be required)
