Prices vary depending on the date of the flight, destination and whether it includes a return trip.

A round-trip ticket from St. Louis to Paris next May, for example, cost $499.98 for “basic” service that includes the ticket and one personal item. For $690.50, the same flight would also include a carry-on bag and a checked bag.

A business ticket, for $891.84, would offer cancellation protection, an in-flight meal, extra legroom and priority boarding, in addition to a carry-on bag and a checked bag. The flight would include a layover in Iceland for a little over an hour.

“We only charge what you use,” Wow founder and CEO Skúli Mogensen told the Post-Dispatch in a telephone interview. Mogensen started the airline in 2011 after working in technology and the telecom industry.

In addition to lower prices, his airline’s philosophy is to offer better communication with travelers in a fun environment. The company’s name and signature color on its fleet, bright purple, are intended to make the airline stand out.

“We wanted to make flying fun again,” Mogensen said. “I do believe the airline industry can be improved significantly.”
