I'm trying to book an inter-ID flight, DPS>SUB and I've given up on the website. It doesn't accept my Visa card. I tried to call all phone numbers posted for USA and CDN and no answer except at CDN when I got a recording saying they were not open weekends. Ok, I guess I can wait until Monday, unless I find something better for my routing in the in between. Maybe I should just skip GA. I agree with the other posters who find it amazing that the GA website seems so problematic WRT credit card acceptance.
