Personally, I don't understand the need for the new URL. The rationale outlined in the Denver Business Journal, as well as F9's own press release states, “Booking at FlyFrontier.com is the best choice as it’s the only place you can book Frontier travel where you’ll get an advanced seat assignment, earn more EarlyReturns® miles, and enjoy more choice in your overall travel experience." Couldn't that ALL have been done within the existing URL?
So, for those of us who already book our travel via the F9 web-site, what are the more choices they are offering today that they didn't offer yesterday?
