I have been having his problem for the last 2 days. I thought it just my computer not loading right. I haven't tried the site again tonight but earlier it wasn't working.
I'm glad I saw this thread. I was trying to book my May airfare on Southwest yesterday and I couldn't get it to look up airports. I thought it was just my computer. I'll have to check again this morning to see if there are still issues.
Bloomberg stated parts of the SW website crashed yesterday due to online job seekers. The company was taking applications for flight attendants and was swamped.
