Former Wow operations chief Arnar Mar Magnusson will head up Play, which will initially serve Europe before expanding its operations to North America in the spring.
Play will, by summer 2020, operate a fleet of six Airbus A321 aircraft, which it intends to expand to 10 “within three years”.
Ticket sales will get under way this month, although Play is yet to reveal any of its destinations.
In a statement, the new carrier said it would draw on a “wide range of experience” from across the aviation sector, including former Wow Air and Air Atlanta staff.
