Travelers flying from Hawaii to the East Coast can expect to spend upwards of 11 hours in the air. It’s no surprise that in the past decade, many airlines have significantly improved business and first class offerings, including lie-flat seating.

Many U.S. airlines now offer lie-flat seating as part of their domestic business class service, but which ones, and on what routes? Here’s exactly which carriers’ flights within the U.S. allow you to fully recline while you fly.

JetBlue

JetBlue’s Mint experience (the airline’s name for business class) is offered on certain coast-to-coast and Caribbean flights, including long-haul travel between New York, Boston, and Florida, to Seattle, San Francisco, Los Angeles, San Diego, and Las Vegas. Each Mint Suite™ offers direct aisle access, a sliding door for privacy, a fully lie-flat seat built with adaptive foam cushions, a memory foam pillow and a customizable blanket.  The Mint experience also boasts the longest fully lie-flat seat (6’8″) on a domestic premium flight—perfect for all you former NBA players turned globetrotters.

American Airlines

American also offers fully lie-flat seating on flights using their Airbus A321T, the airline’s premium jet. As of February 2023, the A321T flies from New York to Los Angeles and San Francisco, so travelers heading from the Big Apple to the Golden State can expect to do so in style. Fliers on this route will be treated to a 15.4-inch high-definition touchscreen, fluffy pillows, Casper bedding, multiple USB ports, and Bose noise-cancelling headphones.

United Airlines

United Airlines offers fully lie-flat seating on many of its domestic routes. In fact, if you’re traveling a long-haul itinerary with pairings between New York, Denver, D.C., Honolulu, Texas, Los Angeles, Orlando or San Francisco, there’s a strong chance the premium cabin will include fully lie-flat seats. However, if you’re truly set on securing a lie-flat seat, note that the airline advises contacting them at the time of booking, as some aircraft with business class on these same routes will not offer the service.

Hawaiian Airlines

As mentioned above, Hawaii is home to the start (or end) of three of the longest domestic flights in the world. If you’re hoping to catch some shut-eye ahead of your tropical vacation, you’re in luck. Hawaiian’s Airbus A330 first class cabin features fully lie-flat leather seats which are more than 20 inches wide, and 6’3″ inches long. The seats feature premium bedding, privacy screens, and an adjustable in-seat tablet arm that allows for comfortable viewing at all angles.

Delta Air Lines

A Delta One seat, the same service that international Delta business travelers receive, includes 180-degree, fully flat-bed seats. These lie-flat seats, which also include a massive 18-inch screen and privacy dividers, are also offered on several domestic routes: Boston to Los Angeles, JFK to San Diego, Los Angeles, Seattle, and Vegas, as well as Atlanta and Minneapolis to Honolulu.
