It’s the first plane to feature United’s new interior, which was delivered just a few days ago. Keep scrolling for a first look inside United’s new cabin.United’s announcement on Tuesday was met with a lot of excitement, but it’s important to keep things in perspective. The new interiors are regular domestic narrow-body fare.Photo by David Slotnick/The Points GuyFirst class is standard recliner seats, with a few nifty storage nooks and a handy retractable remote so that passengers don’t have to reach ahead of them to pause or change their show or movie.Photo by David Slotnick/The Points GuyNevertheless, the 13-inch screens were sharp, and the seats perfectly comfortable for any domestic hop — or even a shorter international trip, perhaps.Photo by David Slotnick/The Points GuyOne cool feature available at every seat: The IFE screens have Bluetooth connectivity, meaning passengers can connect their personal wireless headphones for use during a flight, no adapters needed.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

The Max 8 features 54 of these extra-legroom seats spread across nine rows, in the standard 3-3 configuration.Photo by David Slotnick/The Points GuyAgain, not a reinvented wheel. But as someone who’s flown a few times recently in American Airlines’ IFE-less, dense 737-800s (which are the same size), these seats certainly felt on the higher-end, more in line with Delta’s cabins that tend to be held in higher regard by travelers.Photo by David Slotnick/The Points GuyThe Economy Plus and Economy seats feature 10-inch touchscreens, which, aside from their size, are just like the ones up in first class. They have a rotating selection of movies, TV shows, games, and more, according to Jaspreet Singh, a product manager at United who works on the airline’s in-flight entertainment systems.Photo by David Slotnick/The Points GuyAnother cool feature: Each seatback screen shows the corresponding seat number during boarding. It’s a nice little addition, and one of those fairly low-effort things that nevertheless adds a more premium feel.Photo by David Slotnick/The Points GuyEvery economy seat — the 54 extra-legroom seats and the 96 regular seats on this particular plane type — has an adjustable headrest with foldable wings.Photo by David Slotnick/The Points GuyThe entire cabin has customized LED mood lighting, United says, which can be adjusted depending on time of day. It’s similar to the lighting Boeing offers with its newer planes, but customized to United’s branding specifications, an airline designer said.Photo by David Slotnick/The Points GuyThe cabin also has redesigned overhead bins with enough storage room for one full-sized carry-on bag per passenger — hopefully eliminating the dreaded gate-check.Photo by David Slotnick/The Points GuyEach bin can fit up to six carry-on bags, the airline said.While the new cabin is not a reinvented wheel, it appears to be a solid product in line with the top domestic offerings — aside from the few unique routes that feature lie-flat products.More: Behind the scenes: Inside Southwest’s 50th-anniversary celebrationUnited’s plan to retrofit the entire fleet is also a good one, and will mean an end to wondering whether you’ll have a nicer seat with IFE on a flight, or if you’ll get stuck with an aged product.
