Actually, you saw an B737-7XX ; AirTran has not yet taken delivery of any -8XX series airframes. The new livery you saw (predominately white with a rearrangement of the stripes, etc.) is the new corporate livery ; it will be on all new aircraft deliveries and the 717s will be repainted as they cycle through heavy maintenance. Currently, I believe AirTran has no more than 4 on property (that's a highly inflated guess) ; current plans call for the delivery of ~58 airframes (a mix of 737s and 717s) in 2005. AirTran is currently operating their 737s on a select few high-density Florida routes (just a few frequencies) and more noticeably on the ATL-DEN run and other « longhaul » segments. As more airframes come on property, they will begin to replace the routes currently operated by the wet-leased Ryan International A230s and Ryan Internation will leave AirTran ops. Also, they will cover other routes normally operated by the 717 as some 717s are transitioned to cover routes previously operated by Air Wisconsin as AirTran JetConnect.
