Going by what was written in post #144. To me it read that it might have been unexpected. I don't do 4 hour layovers, if possible, especially on a flight that is already 5 hours. So it's not normal for me. That makes it a 9 hour flight. PLUS the hour and a half getting to the airport to check in, makes it an a 11-ish hour day for traveling. AND that doesn't include the hour and a half-ish from L.A. or San Diego TO Houston. That's 13 hours for this autistic teen to travel.
Scratch that last part, I just remembered someone said they were traveling from WDW not DL. According to Travelocity, that's approximately a TWO and a half hour flight to Houston, non-stop. With a four hour layover and getting to the airport at the time they want people to check in, that's a 14 hour travel day for an autistic teen.
