I have made my Disney reservations and now for the plane ride........I am wanting to fly Southwest (HOU-MCO) because of cost and proximity to my residence, but SWA is only booking through March 8, 2013 and they won't be opening up further dates until August 27. If you look at United, they have flights available and some already have "5 tickets at this price".....I know they have seats allotted for different reservation options (online, travle agency, etc...). I am concerned that people will start booking one way trips on SWA and the flights will sell out before I get a chance to book. I hate going Delta due to the plane change in Atlanta. Driving is not an option (3 hours is the most I can handle!!).........any thoughts or fear-calming suggestions?
