To the OP, our return home on a Saturday morning was horrific also.. our wait time in line was 40min, and the curbside checkin was running the same amount -that line stretched pretty far back. Several folks in front of us missed their flights.
We had a rental car and left our resort, turned it back in and got in line to wait to check bags...my DH wondered why I wanted to get to the airport early - when he saw the line, he realized why.
This was late June, the height of travel and I understand that air travel on any airline is hectic coming to and from Orlando. But the way SW handles it is ridiculous. THe worst part was when we did get to the front of the line, and a SW employee was directing folks to the next available kiosk, they had very few kiosks open. It made no sense. I'd hate to see that place around a holiday, ugh.
