This is just a minor inconvenience, but there was a problem when I tried to do the 24 hour check-in this morning. I was ready and waiting to push "enter" at 6:50 am, exactly 24 hours before flight time. It wouldn't take - said to check Conf. #, name, etc.; everything was correct. Finally I called SWA. By the time they answered, checked why I couldn't check-in (a "glitch" on their end) and fixed the problem, we got C-11 & 12. I'm not too happy with these boarding tickets. We aren't particular where we sit, but we do like to sit together. This may or may not happen with C 11 & 12. On the brighter side, we're going to LV and we both got TSA PRE.
