This year we are paying a little bit more than we usually do, as we are going in June instead of May or Sept. The fare was $124.
Sign up for the emails, but also just check every Tuesday, when the fares come out.
The SWA direct flights from STL fill up rather quickly. Be aware that those flights come in from Midway before continuing on to MCO, so weather in Chicago can cause departure delays. We used to take the last flight down to MCO, but now we have switched to the second-to-last; weather is often an issue at the time we go, and we got tired of arriving at 1 am. The flight back originates at MCO, and it has been right on time every time, sometimes it even arrives early.
I recommend using Park Express for airport parking at Lambert (they are located @ I-170 and Natural Bridge, east of the airport.) They are just WONDERFUL, I can't praise them enough. If you go to
www.parkexpress-stl.com, and sign up for their club card, they will send you a coupon for 7 days free parking when they send the card. It takes about 4 weeks, so sign up well ahead of when you need the parking.
