This is what it's like to travel on budget airline WOW Air, which flies London to New York for £139

LONDON - Earlier this month, Icelandic low-cost carrier WOW Air announced that for a limited time it will offer tickets from the West Coast of the United States to Europe, and vice versa, for as low as $69.99 (£57).

At the time of writing, some of their best fares from London include £139.99 to Boston, San Fransisco, Miami, New York, and Washington D.C.; £149.99 to Los Angeles and Toronto; £159.99 to Montreal, and £179.99 to Pittsburgh. Flights also depart from Edinburgh and Bristol.

As the sale, available on one-way flights between January 15 and April 5, 2017, is an effort to expand WOW's US customer base, the flights from Europe to the US aren't discounted as heavily.

Furthermore, some of the amenities typically included with a plane fare - including bottled water, food, and even entertainment - aren't part of the deal. However, the airline is up front about its no-frills flights.

"This way you won't have problems with expectations," said WOW Air founder and CEO Skuli Mogensen. "That's why we tell them to bring their own food, water, and download a movie on your iPad or laptop ahead of the flight."

And with prices like the above, the airline is still worth a look, especially with European low-cost carrier Norwegian Air also expected to launch $69 transatlantic flights later this year.

We asked two travel experts who have flown WOW Air, James Dozer of Travel Codex, who bagged a $99 one-way flight from Los Angeles to Reykjavik, and frequent flier and travel expert Gilbert Ott, who runs the air miles site God Save the Points, to share their experiences.

From quirky purple sick bags to iPads for rent, see what it's really like to fly with WOW Air, and determine for yourself if it's worth the hype.
