Making money or not, this kind of service is explicitly forbidden by Southwest.com's Terms of Conditions:
"You may not use Southwest's sites for or in connection with offering any third party product or service not authorized or approved by Southwest. For example, online check-in service providers may not use Southwest web pages to check-in Customers online or attempt to obtain for them a boarding pass in any certain boarding group."
Correct. Early bird and A-List automatic checkins occur 36 hours prior to the departure of the flight. The general boarding checkin starts 24 hours prior.
Southwest Airlines automatically reserves a boarding pass for A-List Members beginning 36 hours prior to scheduled departure of the Member's confirmed Southwest Airlines flight.
I don't think we've previously seen someone publicly offer this service for free. It'll be really interesting to see what the company does in response -- thanks for going out on a limb for us all to find out!
dude - this is a great idea. i always assume that you couldnt do this because southwest did not open their apis (aka why they are not in hipmunk, kayak, etc) how did you build it?
