Icelandic airline Play is making family travel easier by offering $2 fares for kids when an adult books a trip to Europe.

The heavily discounted kid tickets are available when an adult books a roundtrip flight from the United States to Iceland, Copenhagen, Paris, London, Amsterdam, Dublin, Berlin, or Liverpool by 11:59 p.m. ET on Sept. 17, Play told Travel + Leisure. To qualify, kids must be under 11 years old.

“International travel is a way to both bring families together and expose children to new cultures, foods, and experiences,” PLAY CEO Einar Örn Ólafsson said in a statement shared with T+L. “Families with young children can’t always make it across the Atlantic with high travel costs, and PLAY designed this deal to welcome families to our flights to travel together and make memories in Iceland and other amazing destinations.

“These $2 fares for kids are our lowest yet, and we hope that families take this opportunity to cultures, cuisine, and educational visits together,” Ólafsson added.

The $2 kids fares are valid for one-way flights and available for the lowest basic fare. Play’s basic fare includes a personal item, but does not include a carry-on or checked bag or seat selection. 

The sale is valid for travel from Sept. 29 to Oct. 6, from Oct. 8 to Oct. 20, from Oct. 22 to Nov. 3, and from Nov. 5 to Dec. 15.

The promotion is available to use on the cost of the airfare, but does not include taxes, fees, or carrier charges.

Low-cost carrier Play first started operating flights in Europe in 2021 before launching its first flight from the U.S. the next year. The airline operates a "hub-and-spoke model" in which all flights connect through Reykjavik before heading on to other destinations across Europe, and flies an Airbus fleet, including the A321neo and A320neo aircraft.
