The beauty of these airlines is you don't need to buy a roundtrip ticket. I know you probably will, but it's nice to have that option, right? The catch is these sales are valid for today only and valid for travel through June 8.
Flights between 80+ cities from coast to coast are discounted. Whether you live in a major city like New York or Los Angeles, or a smaller town like Akron or Wichita, there are discounted fares for you.
