Getting outta town has been delayed until further notice.It’s probably not surprising that when Southwest Airlines announced a summer sale with one-way fares as cheap as $49, travelers were delighted. They were so delighted that they’ve overwhelmed the carrier’s site, making it difficult for customers to book new flights, or to print their boarding passes for travel that’s planned for, um, now. Problems with the website mean long waits on the phone, too: users report being unable to get through by phone or the company’s website.
