I feel like I’m in the minority when I say that I really like the seats in United A321XLR Polaris business class.
Many have criticized them for being coffin-like and claustrophobic. They dislike how narrow the seat is. And they absolutely hate how the seats face away from the windows (making it difficult to look outside).
Me? I’m willing to agree with them about the window thing, but as a guy who craves privacy and seclusion, I consider the “coffin-like” thing to be a feature. Not a bug.
I enjoyed it so much that it got me thinking about cancelling my plans for a traditional coffin and going with one of these bad boys instead.

My full review of United A321XLR business class from Washington, DC (IAD) to San Diego
Full disclosure: this was a domestic flight, sold as domestic first class. They didn’t offer the full long-haul Polaris business class experience, but I feel like I got a pretty good sense of all its quirks and features on this 5 hour transcontinental run to the west coast.
Checking in at Dulles International Airport
I strolled into the airport at 6:52 AM ready and raring to go for this 9 AM flight to San Diego. I know. Anyone who has traversed IAD over the past 10 years or so knows that this is irresponsibly early. Let’s just say that it ain’t the nicest airport for killing time in when you don’t have lounge access.
The boarding process
Déjà vu gently tapped on my shoulder and let itself be known in the moments leading up to the boarding process. If you recall the last time I flew from DC to San Diego (in United 777-200 domestic first class), it was a nearly empty flight with an eerily empty gate area. It wasn’t quite as bad this time. But it was close.
Boarding started at exactly 8:10 AM, and I found it interesting that nobody rushed to line up in the designated Group 1 and 2 lanes. Everyone held back, seemingly carefree and uninterested in a way I have never witnessed at an airport anywhere in my entire life.
Perhaps they had all read my scathing review of United A321XLR economy? I’d be cautious too after reading what I had to say about that.
United Airlines A321XLR business class seat and cabin overview
There are 20 Polaris business class seats arranged in a very private 1-1 layout on the A321XLR. It’s very similar to the JetBlue Mint Suites. Not a whole lotta difference here.
This is a very private and secluded seat design featuring retractable privacy doors. And yes. They are narrow. So narrow that those of you with wider hips may have difficulty squeezing in and out of it. It’s tight.
These suites are so private that you won’t see anybody else seated around you once you’re seated. Except for the reflection of the person sitting across from you in your video screen. It’s as easily awkward as it was in the alternating front and rear-facing seats in British Airways 747-400 Club World.
Amenities
Because this was a domestic flight, we did not get an amenity kit or Polaris-spec blankets and pillows. You’ll get all that stuff on international flights however.
But they didn’t totally neglect us. Blankets, noise canceling headphones, and pre-departure drinks were offered. No pillows, though.
The departure from IAD
It was raining hard just prior to pushback from the gate. Like “just watch, they’re gonna delay this flight” kind of rain. But it was fine. So fine that we actually pushed off the gate four minutes early at 8:56 AM. Well then!
Taxiing out to the runway was a bit of a kerfuffle unfortunately. It took 28 minutes to reach the threshold of runway 30, delaying our takeoff time by 13 minutes. It was 9:23 AM at liftoff.
In flight entertainment
You’ve heard me say amazing things about the United Airlines in-flight entertainment system in a lot of other reviews recently (United 787-9 Premium Plus as an example). In an effort to not repeat myself, I’m just going to focus on the XLR-specific things for this overview.
The video screens are interesting. They pop out from the wall, creating a privacy barrier between you and the aisle (and the flight attendant serving you food and drinks). I quite liked this closed off feeling, but I’d imagine that the flight attendants don’t like having to reach over it when serving meals.
The video screens are huge, very high resolution, an extremely bright. They’re nice.
The noise canceling headphones they provide are a perfect match for the high-quality video entertainment. They sounded great with deep bass and respectable midtones and highs.
Free high-speed Starlink Wi-Fi is available on the United A321XLR. As it has been on all of my other United flights recently, the connection was rock solid and extremely fast.
The meal service
Although what I’m about to show you isn’t exactly what you’ll be served on long haul international flights, it’s pretty close. United isn’t exactly known for creative (and decadent) food, but it’s always pretty good.
They served breakfast on this flight. There were six options total, and all of them looked fairly good. I went with the traditional eggs and sausage option.
Seat comfort
My only criticism of this Polaris business class seat is the fact that the headrests are extremely small and unsupportive. Even when the seat is in a fully upright position, it’s positioned too far back to be comfortable. Bigger is better (she said).
These seats are narrow, but I found it extremely comfortable to sleep on in a fully lie flat position. I’m guessing that it’ll be a bit too firm for most people’s tastes, but I like a firm bed. I did wake up from a deep two hour nap feeling completely pain-free, and I could still feel all my limbs, so it wasn’t terrible.
Business class lavatory
Unlike all the domestic-configured A321s in the United fleet, they put some dough into the lavatories here on the long haul A321XLR. They look nice covered in decently high-quality materials.
The descent and arrival into San Diego
I didn’t mean to sleep as long as I did. My goal was to spend 10 to 15 minutes testing out the lie flat seat, but somehow it got a little too cozy. 10 to 15 minutes ended up being two hours. It was the bright cabin lights that woke me up just prior to arrival in San Diego.
We touched down on runway 27 only 4 minutes late at 11:19 AM. From there, it was a short 5 minute taxi over to Terminal 2, and we were docked at gate 45 one minute early at 11:24 AM.
Pros and cons of United A321XLR business class
Honestly? If I had the choice between an A321XLR and a widebody aircraft for a long haul international flight, I’m always going to choose the widebody. Higher ceilings and wider cabins makes all the difference on those longer flights IMHO.
Pros
- These are some of the most private business class seats that I have ever sat in.
- The finishes and materials are top-notch. United spent some money on these seats.
- All the tech (wireless charging pad, power outlets, huge video screen, Starlink, etc) is very much appreciated.
Cons
- Anyone who suffers from claustrophobia might not like how confined these seats are.
- The video screen (when swung into its open position) makes interactions with the flight attendant awkward.
- All seats face into the cabin away from the windows. It’s an awkward seating configuration I learned to dislike in Virgin Atlantic A340-600 Upper Class way (way) back in 2016.
