What It Costs To Fly In Lie-Flat Seats On The Boeing 737 MAX In 2026

Lie-flat business class used to be the reward for choosing a widebody aircraft. This kind of long-haul cabin was formerly reserved exclusively for twin-aisle jets. In 2026, some of the most interesting lie-flat seats in the sky will be found on a more commonplace aircraft, one that has increasingly become a core piece of most airline fleets. Three carriers have begun to add lie-flat business class seats to their Boeing 737 MAX family jets. Singapore Airlines operates fully flat business class beds on its Boeing 737 MAX 8 jets for high-frequency regional routes across Asia. flydubai has also started to use the MAX as a widebody substitute, with lie-flat seats and some aircraft even featuring suite-style layouts that lean into privacy.
