Price wars on flights from the US to Europe have made the $99 flight a somewhat frequent sight. But you still have to jump on it when they're available. A new sale from WOW Air is offering one-way flights for $99.
It's not just the price that's notable in the sale. WOW Air is celebrating the addition of St. Louis to the list of US cities it services. The first WOW flight took off last week. Though, St. Louis isn't the only city with sale flights. You can dig up flights for as little as $99 one-way or $199.98 round trip out of Boston ($99), Chicago ($99), Cincinnati ($99), Cleveland ($99), Dallas ($129), Detroit ($99), Los Angeles ($129), New York ($99), Pittsburgh ($99), San Francisco ($129), and Washington DC ($99).
