WOW air has deferred its relaunch from October 2019 to December 2019 and plans to open ticket sales in November, parent USAerospace Associates.

"Significant market adjustments have taken place since the announcement of the re-launch of WOW air. This contraction of air carriers has provided an increase in aircraft inventory previously not available in the late summer. WOW air will take this opportunity to acquire and reconfigure our launch aircraft in the best interests of our customers and shareholders," USAerospace Associates said.
In early September 2019, Ballarin announced that USAerospace Associates will take a 49% stake in bankrupt WOW air, acquiring its brand and certain tangible assets such as uniforms. Investors in Iceland will hold the rest of the capital to comply with European Union airline ownership rules. The company will be based at IAD airport but its route network, schedules, and fleet details have yet to be announced.

The recent bankruptcies of Thomas Cook Airlines UK (MT, Manchester Int'l), Aigle Azur, and XL Airways France have not only shaken the European market but also released a significant number of second-hand aircraft now available for new leases.
