Continental has a flight that leaves at 5:15am, layover in Houston of 40 minutes and requires you to change planes. It arrives at Orlando at 1:45pm.
We thought about that but airfare was not low enough considering the $50RT per piece of luggage you'll pay along with having to change planes. Southwest does not charge for luggage up to two per person.
So we opted for Southwest and leave on a Saturday on an 8am flight that arrives in Orlando at 4:20pm, has 1 short stop and no plane change.
Our return leaves Orlando at 3:15pm and gets to Phoenix at 5pm nonstop.
I noticed SW's schedule changes substantially starting Oct. 1st.
