Flights to DSM - why so cheap?
I'm planning travel to Des Moines for late August. Looking at itineraries to Des Moines for August 15th - 19th (Tues - Sat) I'm finding fares are $300 from SFO, $260 from BOS, on both United and American. UA claims this is "everyday low fares", but I'm puzzled because there are no discount carriers in DSM and this doesn't include a Saturday night stay, so I'd expect the fares to be $500+. Any idea why so cheap, and how long this might last?
