Most airlines that offer lie-flat seats in business class only have them on larger aircraft such as the Dreamliner, A380 and Boeing 777. Nevertheless, there are a few carriers that offer lie-flat seats on single-aisle jets including the A321LR, A321XLR, A320 and Boeing 757. For those of you who may find yourself with a premium ticket on one of these aircraft can rest assured you’ll be able to rest well on your flight with the following airlines and routes.


JetBlue is one of the US airlines that offers lie-flat business class seats for flights between New York and London, and New York or Boston to the Caribbean. JetBlue has a lie-flat business class called Mint business class on the A321s and soon A321LRs and A321XLRs.

United Airlines

Another US airline that offers lie-flat business class seats on single-aisle jets is United Airlines aboard their A321s and Boeing 757s. The carrier has ordered Boeing 737 Max aircraft to add to their fleet, but no one will be able to fly in them until these jets get the go signal to take off again. Those traveling between the East Coast to Europe such as Ireland and Scotland, and New York or Houston to the Virgin Islands can fly in business/first class in comfort.

American Airlines

Next on the list is American Airlines, which has lie-flat seats in premium cabins aboard their fleet of Boeing 757 and A321 jets. Those who travel between Miami and Brazil as well as from Dallas to Peru will be able to book a business class seat that goes beyond a simple recline. Looking to test these lie-flat seats on a domestic flight? You can do so by flying between New York and Los Angeles or to San Francisco, or between Los Angeles and Miami.

Delta Air Lines

Seats that convert into a fully flat bed are available on Delta Air Lines single-aisle, Boeing 757-200 jets called Delta One. These aircraft fly from New York to Spain, Washington, DC to Los Angeles, between New York and Los Angeles and to Seattle, and between Boston and Los Angeles.

Philippine Airlines

Those traveling on Philippine Airlines can enjoy lie-flat business class seats on their A321neo jets, which operate flights between Manila and Australia. The award-winning airline is one of the few carriers in Asia that owns and operates a single-aisle jet with a business class seat that converts into a fully-flat bed versus only reclining to a certain degree.


Saudia, an airline that continues to strive to be a certified five-star airline, does offer lie-flat seats on the A320 and A321LR aircraft. Those traveling between Saudia to Europe can enjoy sleeping soundly in business class, specifically on flights to Germany, Italy, Austria and Switzerland. Saudia may consider adding the A320 or the A321LR with a lie-flat business class for flights to the UK and India in the future.

TAP Air Portugal

TAP Air Portugal is one of Europe’s well-known airlines that provides lie-flat beds in its premium cabin on a single-aisle jet—the A321LR. Those who are flying between Portugal and New York and to Brazil have the option to book a business class ticket and sit in a seat that converts into a flat-bed. The airline has also opened up flight routes between Portugal and Washington Dulles, which also uses the A321LR aircraft with lie-flat seats.

Air Astana

Travelers flying on Air Astana, based out of Kazhakstan, can enjoy lie-flat seats on the A321LRs, which flies between Kazhakstan and UK, Moscow and Paris (beginning June 2020). Late last year, Air Astana announced it will also offer lie-flat business class on the A321LR on flights to Hong Kong, Thailand, South Korea and Malaysia, and possibly to Czech Republic, Saudia Arabia and Singapore in the near future. The A321LRs will slowly replace all of Air Astana’s Boeing 757s.
