We leave Disney 2 to 2 1/4 hours prior to our flight. Allowing for 30 minutes to drive to the airport, we are there 1 1/2 to 1 3/4 hours before our flight as SWA recommends arriving 1 1/2 hours beforehand. Once during spring break we encountered a long line at security but still had plenty of time before boarding.
Now, on the other hand, when we drive to St. Louis or Kansas City from our home in mid-Missouri we leave 4 hours before our scheduled flight. Even though it's usually only a 2 1/4 or 2 1/2 hour drive and SWA recommends that you should be there 1 hour prior to your flight, we want to allow for breakdowns, traffic jams, wrecks, etc. as we sure wouldn't want to miss our flight to Florida!!!!!!
