Isn't this just for the international routes that they'll be picking up from AT? I don't blame SWA for wanting to contract that service out. International service is not only new for SWA but it's so unsure that I would think that they would want to test the water first before committing to hiring full fledged employees outside the US, I mean, what if they are not successful in Costa Rica an decide to pull out. Then, instead of voiding a contract, they'd be repositioning employees from outside the US...
I don't know, but if I had to make that call, I'd want to test the waters first.
