Just a side note... SWA has started doing an "early bird check-in" which is $10 each way. Below is the information from the website. It says it doesn't guarentee you an A boarding position, but so far, that's all I've received since I started using it! It's been very convenient, I use it when I travel and sometimes it's difficult to get the boarding pass printed. Last year at WDW I went crazy trying to get it done so I wasn't stuck riding on the wing...Just love this feature!
BETTER BOARDING POSITION
We'll automatically check you in and assign your boarding position within 36 hours of your flight's departure - that's 12 hours before general boarding positions become available. While EarlyBird Check-In doesn't guarantee an A boarding position, it improves your seat selection options to help you get your favorite seat.
Anyway, thought I'd just pass it on.
