I read that WN/FL is working on connecting their flight schedules. However it will be not a codeshare but it will be NETWORK CONNECTIVITY. Which has been long awaited in this merger. As it stands now WN is planning on having FL intergrated into WN by 12-31-2014 ( that is the gold). If you book via southwest.com and you connect from a WN flight to a FL you will not pay for bags. But if you book at airtran.com you will pay for bags. So bottom line at this point if you book fron the FL site you pay for bags but not on the WN site. It is going to be interesting on how this all unfolds. With FL adding alot of flights to Mexico from various cities this will finally give WN the ability to feed these flights. This new Network Connectivity is rolling out with full functionality end of 2nd quarter.
