These 6 airlines offer beds in economy, with prices ranging from $150 to $2,600. Here's how to book them.

Air New Zealand markets its economy beds as added options for coach flyers. The Skynest is the newest product and will be two sets of three-high flat bunks with linens, curtains, and seatbelts.

Air New Zealand is showing its Skynest off to the public in New York City on April 14.

The legrest-equipped Skycouch revolutionized economy air travel and became a blueprint for other airlines. The legrests flip up 90 degrees via a button and lock into place to make the flat sleeping surface.

It comes with linens and a "cuddle belt" to wear when sleeping, but customers still get the regular economy meals and boarding position. I flew in the Skycouch for 16 hours in 2022 and thought it was comfortable and a great sleep solution if you have the budget. The bed is just over five feet long, though, so taller travelers may be more cramped.

Passengers can secure the Skyouch at the time of booking. The price can vary by season and route, but the most expensive one-way tickets are over $1,500. It can accommodate up to two adults and a child.

Launching in 2027 on long-haul flights, the Relax Row mirrors the Skycouch and will be fitted onto more than 200 Boeing widebody planes by 2030.

It can be selected at booking and comes with two extra pillows, a blanket, and a mattress pad. It's unclear what the launch route will be.

ANA, another Star Alliance member airline, sells the COUCHii on flights between Japan and Hawaii. It is bookable up to 48 hours before the flight, either by requesting it on the website or by phone.

COUCHiis are exclusively on Airbus A380 planes and stretch three or four seats with legrests that flip up to create a wide bed.

ANA's website shows the cheapest option is $130 for all four seats for four people traveling together during low season; the most expensive is $2,580 for four seats for one person during high season.

The German flag carrier offers first-come, first-served "Sleeper Rows" that can only be booked at the airport for select long-haul flights of at least 11 hours, subject to availability.

Essentially, Lufthansa passengers can pay extra right before their flight to secure an empty row that would otherwise have gone unsold.

It doesn't have flippable legrests, but it comes with "business-class quality" linens and space to stretch out. The per-segment cost ranges from $209 to $299.

The Kazakh airline allows travelers to pay to reserve a row of three seats on select flights to Beijing, London, and Frankfurt. It comes with a blanket, mattress cover, and pillow, but no flippable legrests.

The ticket also includes business-class lounge access, priority check-in, and two extra checked bags. Air Astana says the experience is a "nominal" increase over the regular economy fare.

The SkySofa is another upcharge for a guaranteed row of three empty seats for one person; it can be added at booking or after.

Vietnam Airlines offers the option on flights between Vietnam and 18 countries, including the US. It includes personal amenities, like an eye mask and socks, and meals equal to those in premium economy.

The SkySofa price ranges from $150 to $650 one-way, depending on the economy fare type booked and the route.

China Airlines began marketing the "Family Couch" in 2014 but pulled it in 2018 due to low demand. Defunct UK airline Thomas Cook had a "Sleeper Seat" that flew until the airline declared bankruptcy in 2019.

Azul Brazilian Airlines, which once offered a four-seat-wide "Sky Sofa" on Airbus A330s, told Business Insider that the product was "discontinued due to fleet renewal and the configuration of current aircraft."

French carrier Air Austral's website mentions a bed-like "Extra Couchette" on Boeing 777s, but current seat maps and booking options don't show it. It's unclear if it's been discontinued; the airline didn't immediately respond to a request for comment.
