Play flies its shorter hops around Europe on a fleet of smaller Airbus A320 jets; and its transatlantic flights are via the longer 192-passenger Airbus A321 version. For international flights, seats are configured in rows of six, three on each side of the aisle, in an open layout—it's all one class.

PLAY, the Icelandic low-cost carrier, operates a modern, fuel-efficient fleet consisting exclusively of Airbus A320neo family aircraft. Specifically, their fleet is comprised of the Airbus A320neo and the Airbus A321neo. These "Next Generation" narrow-body jets are ideal for PLAY's hub-and-spoke model, allowing them to fly from their base at Keflavík International Airport (KEF) to both European cities and North American destinations like New York, Washington D.C., and Toronto. The A321neo, in particular, is used for longer trans-Atlantic routes due to its impressive range and capacity (seating up to 214 passengers in a single-class configuration). By utilizing a single aircraft family, PLAY minimizes maintenance costs and streamlines pilot training, a common strategy for successful low-cost carriers. In 2026, the airline continues to focus on these eco-friendly models, which offer significant reductions in fuel consumption and noise compared to older generations of aircraft.
