United A321neo Economy Plus review: all of the stretch with none of the buzz

United A321neo Economy Plus

It’s no secret that I’m a fan of United’s Economy Plus product. It’s a lot of extra legroom for not a lot of extra price (usually), and it’s my go-to seating selection on any United flight longer than two hours these days. 

I recently got to try it out on their A321neo. The routing was San Diego to Denver, which clocks in at just a tick over two hours. So of course I had to do it. You know, that whole “go-to” thing. 

The seats were narrow. Kinda hard. No free alcohol was provided. 

But that legroom! You’d be surprised how much a little extra stretchy space offsets the lack of padding and a good buzz.

My full review of United A321neo economy plus from San Diego to Denver

Expecting Economy Plus on United’s A321neo to be better than it is on all of their other narrowbody aircraft wouldn’t be illogical. After all, this aircraft features various cabin enhancements and improvements over other aircraft in United fleet. I went into this with elevated expectations…

Arrival (and checking in) at SAN

This flight was scheduled to depart at 6:35 AM. I stumbled into the airport just after 5 and made a beeline straight for the security checkpoint.

And wouldn’t you know it, I noticed that the United baggage drop and check-in counters were wide open. How come that kind of thing never happens when I have bags to check?

If only there was some kind of information available that could tell me exactly where I need to go and what time I need to get there by. Oh well. Seems as if I’m gonna have to wing it today.

“Oooh, there’s probably a really funny way of tying the ‘winging it’ thing to the fact that I’ll be flying to Denver in United A321neo Economy Plus this morning. It’s going to be a hilarious pun for the review!”

This pic is a reminder to stop and look up the next time you’re traversing through SAN. They put a lot of effort into the style and design of this place, and it’s a shame that we’re all too busy trying to weave clever puns into airline reviews to even notice it.

It’ll also behoove you to scan to your left and right as you make your way to the gate. See that Pannikin over there? I guarantee whatever they’re selling will be more delicious (and substantial) than the free stuff they’ll be slingin’ in Economy Plus.

I’d also recommend hanging out near the Delta Sky Club just in case anyone falls overboard (so you can swoop in to take their spot before anyone notices).

Here’s the A321neo that’ll be taking winging me all the way to Denver this morning.

I especially like how there’s a sign for baggage claim and ground transportation just above the boarding gate (which would be super helpful for anyone having second thoughts I guess). What is United not telling us about the enhanced economy experience they are about to present us with?

The boarding process

Even though they got the boring process started exactly on time, it felt like they were taking forever to get the process started. Reality flows like molasses before 6 AM I guess.

My boarding pass. This has exactly 120 characters on it by the way (which I only know because it took them forever to get the boarding process started and I was getting bored).

Economy Plus passengers get to board with Group 2. It’s a big group though, and I certainly didn’t feel special standing in that long boarding queue.

The time: 05:42. The place: Gate 45, Group 2. The feeling: Proud as all get out knowing that I’ve just stumbled upon yet another potential pun. I was bored. During the boarding process. Get it? Ha! (You’re sure that you get it, right?)

I didn’t have the heart to tell the hungry-looking guy on the left that eggs benedict served atop toasted truffle butter infused artisanal brioche with a side of pan seared duck bacon is not something they normally serve in United A321neo first class. I hope he enjoyed the reheated southwestern scramble.

United A321neo Economy Plus seats

There are 27 Economy Plus seats on the A321neo. It’s a standard 3-3 layout, with 4 1/2 rows total. The extra legroom is approximately 4 inches over standard economy. If you’ve flown Delta A321neo Comfort Plus recently, this will feel pretty much the same.

The mood was slightly more somber back here in Economy Plus. Dude looks pissed AF that he didn’t bring a larger carry-on bag today. I get it, man. Those overhead bins are huge!
United A321neo Economy Plus row 9, seats A, B, and C
Economy plus. Row 9. Seats A, B, and C. The guy sitting in 10A doesn’t seem all that bothered about the overhead bin space, but his stiff body language seems to imply that he’s second-guessing his decision to pass on the Southwest 737 MAX 8 Extra Legroom thing. “At least they still allow us to get drunk on Southwest.”

I’m definitely not gonna be bored while winging it to Denver with legroom this generous.

These seats feature large video screens (which have a tilt feature built into them for easier viewing). There are USB A and C charging ports, and full-size electrical outlets.

Think of this as United 737 MAX 8 Economy Plus, because, well…this is the same as United 737 MAX 8 Economy Plus. And Economy Plus in every other narrowbody in the United fleet these days.

“It’s the same!” he says (as he looks out a window that is clearly smaller than the Boeing 737 windows).
United A321neo Economy Plus under seat storage space
My backpack says that under seat storage space is fine (and that I wouldn’t believe how icky and gross it is down there).
United A321neo Economy Plus video screen
“Oh I’d believe it,” I said. “The video screen (which looks to be a 13-incher) is covered in icky stuff as well.”
Full size power outlet located beneath and between the seats in United A321neo Economy Plus
That was the exact moment that this 110 V electrical outlet chimed in. “Seriously. You guys have no idea what happens in here on a daily basis.”
United A321neo Economy Plus mood lighting
The mood lighting isn’t quite as good as what you saw in my United 737 MAX 9 Economy Plus review. Previous claims of this being exactly the same as the Economy Plus experience on other UA aircraft are still valid as long as we’re not talking about windows or mood lighting. And probably cabin width, ceiling design, and overhead bin space. You know, the little stuff.

The departure from San Diego

They got us pushed off the gate 9 minutes early at 6:26 AM. Of course they did. Not having a tight connection to make in Denver (or any connection at all for that matter) guaranteed an early departure. We totally would’ve been late if I had a tight connection to make.

Seat 9A is the one you want if what you want is a fantastic view of what everybody wants: a fantastic view.

An example of the fantastic view of what everybody wants. I’m referring to the return of TWA of course (not the high-mileage 13 year old 737-800).
Legroom in United A321neo Economy Plus if you're over 6 feet tall
Real talk: legroom in these Economy Plus seats is spacious only for those under 6′ tall. I’m 5′-10″, and you can see how much room that I have between my knees and the seat in front of me. The guy in the aisle seat was over 6′ and he’s clearly bottoming out.

The airplane equivalent of knees rubbing up against the seat in front of them. They got ’em stacked in deep out here this morning!

It was a long 27 minute taxi out to the threshold of runway 27. By the time we lifted off, we were behind schedule by 8 minutes. Not too shabby for an early morning flight out of San Diego IMHO.

Every pilot’s worst nightmare: the guy sitting in 9A who watches their every move like a hawk via the interactive map screen. “Yikes. That was an awfully sloppy transition from JETTI to ZZOOO.”

In flight entertainment

It won’t be until you start poking around at the in-flight entertainment system that you’ll regret not having a flight longer than two hours.

Being welcomed to the seat that I’m sitting in by the video screen that I’m looking at was kinda flattering actually. It was easily the most human-like interaction that I had so far that day.

The video entertainment system here on the A321neo features United’s latest and greatest setup with all the bells and whistles:

  • Bluetooth connectivity for your headphones
  • Full customization of the user interface
  • A seemingly unlimited supply of content. Apple TV and Peacock too!

All of the human-like pleasantries cease to exist by the time you get to the main menu unfortunately. Not that I expected it to hold my hand as I watched Old Yeller or anything, but a few personalized bits of info and recommendations would’ve been neat.

These aircraft feature free Starlink Wi-Fi for Mileage Plus members. It’s easily as fast and free as they promise it to be.

Food and drink

Unlike Delta, United does not serve free alcohol for their “enhanced” economy passengers. So don’t go thinking that you’ll be popping bottles in Economy Plus or anything. It doesn’t quite work like that.

Despite the lack of free alcohol, they do provide free snack snacks and drinks. One of the things I like the most about United Economy Plus is the fact that I almost always get a full can of my beverage of choice. This time was no different.

What the hell did they do to my precious bag of savory snack mix?? It’s as wrinkly as an old man’s <*redacted*> for crying out loud.

Fun fact: lemonade tastes better when you’re not thinking about old man <*redacted*>.

Food is available for purchase from the in-flight menu. Although, in my experience, it’s just light snacks and junk food. Nothing substantial. 

Economy Plus seat recline and comfort 

I’ve done a lot of Economy Plus reviews over the years, and unfortunately, there’s nothing new to report about it here the A321neo. There’s also nothing worse about it, so I guess that’s a good thing.

United A321neo Economy Plus seat recline
Lot’s going on here: The guy in 8A is showing us the extension limits of the headrest, while the guy in 8C is showing us the limits of seat recline, while the guy in 9C is showing us the limits of the video screen articulation. What a pic!

Legroom is excellent of course. The seats themselves are very hard with limited padding, and there’s no lumbar support to speak of. They’re narrow too! Seat recline is hardly worth mentioning however. It’s the exact same amount that you’ll get in standard economy.

Unfortunately, the guy in 9A has failed to demonstrate how easy it is to cross your legs in these seats (he said something about the table being in the way). What a worthless POS he is.

The descent and arrival into Denver

It’s been a long time since I’ve flown into Denver without even seeing even the tippy top of the Rocky Mountains. The cloud layer was thick all the way in, and there wasn’t much to see until we got underneath it.

Those of you who have become sick and tired of my stupid John Denver / Rocky Mountain High comments every time I fly into Denver will be happy to know that I didn’t see shit today. You’ve been saved by the clouds.

Did I actually fly into Denver if I didn’t see the mountains? That’s like flying Economy Plus without even crossing your legs.

Welcome to Denver!

We touched down on runway 34R 12 minutes early at 9:46 AM. From there it was a very long (and typically Denver) taxi over to Concourse B. It was 10:08 AM by the time we docked at gate B21. And wouldn’t you know it? That was our originally scheduled arrival time. Nailed it!

The modern day / commercial aviation equivalent of riding past the fort of your fiercest enemy. Can you imagine doing this fully exposed on an old horse with a bad hip and blurry vision? The protection that an A321neo provides from arrows and bullets is underrated IMHO.

Remember that time that I flew United 777-300ER Premium Plus, and the live map showing the exact position of our aircraft while taxiing around the airport wasn’t functioning properly? Déjà vu, man.

Well, that was pretty alright. I’ve been winged to Denver many times in my life, but I ain’t never been winged there quite like this.

*And by “quite like this” I actually mean that is the first time that I’ve ever done it on an A321neo. The best SAN-DEN flight of my life was back in April 1998. That was on a 757-200, which automatically makes it the winner.

United A321neo Economy Plus pros and cons

More than anything, I appreciated the fact that this was yet another completely consistent Economy Plus experience. It looked, felt, and even smelled the same as every other Economy Plus experience I’ve had in the last four years. 

Pros

  • You know that I loves me some generous legroom. Disappointed I was not. 
  • The in-flight entertainment system on the United A321neo is world class. 
  • Thanks for the full can! 

Cons

  • The seats are narrow. And hard. RIP to the buttocks (and lower backs) of anyone over the age of 23. 
  • No free alcohol.
  • It’s a bit bland looking compared to the competition. “Corporate” is a pretty good way to describe the design aesthetic IMHO.
