Where to sit on United’s new Polaris 777-300ER


Welcome on board Polaris

With the new United 777-300ER set to enter service with the Polaris product later this week the company finally let some travelers on board to try the plane out. I was one of the fortunate few invited along and, while I spent most of my time in business class during the flight I also poked around in economy class to come up with recommendations of where to sit and, possibly more importantly, where not to sit on board.

Polaris Business Class

There are 60 Polaris Business Class seats on board split into three main shapes/layouts. As with the other 2-class planes United flies the bulkhead seats are likely to be the most desirable thanks to the notably wider foot well. The “straight” seats are next best with a square foot well though not quite as wide. The “angled” seats (even rows) have a tapered foot well that reduces the effective full bed length though compensating somewhat for that with greater width around the elbows.

For couples traveling together the odd row number center pairs offer the best shared travel experience (the divider goes down). If you love window seats and your travel partner (like I do) you’ll be forced to make a choice between the two on this layout.

Row 16 has no windows on either side and row 1 does not have overhead bin space in the center section due to the pilot rest bunks overhead. That shouldn’t be a major problem given the plentiful bins and relatively low passenger density, but if you want your bags directly overhead pick other seats.

From a galley noise perspective row 8 is to be avoided while 6 & 7 may get some overflow. The galley at 2L/R handles all the crew meals so that makes it slightly more busy throughout the flight on typical trips.

And for those looking to change into PJs on board the lav at 2L is your best chance. It is the larger of the accessible lavs on board with a decent amount of room to move around in plus a changing table on which you can put your clothes.

Based on my desire for a window seat, bulkhead and access to the larger lav I believe 9A is the best seat on board with 9L the runner up. I’d pick 1A/L after that and then other odd rows then even rows with 16 dead last due to no window at all.

Economy Class

This is 10-abreast and tight. Finding a good seat is not easy. That said, there are some that are worse than others. The aisle seats measured at a quarter inch narrower than the window and middle seats between the armrests. Arguably that is made up for by the ability to lean into the aisle, but that won’t work so well during the meal service with carts coming and going so be wary. The aisle measures 18″ wide between the armrests.

The bulkhead rows are the only seats with 110V outlets for all passengers; the rest of the economy cabin has two plugs per bank of seats, whether a 3-block on the outside or a 4-block in the middle. On the plus side, the plugs are facing the seats from in front rather than hidden underneath and requiring great contortionist skills to reach.

The worst seat on the plane prize probably goes to 24 A/L. These are exit door seats marked as Economy Plus on the seat map but I wouldn’t want to sit there. They are very close to the door and narrow slightly because of it (~16.5 inches inside the arm rests). Plus they are freezing cold thanks to the exit door. And no window. Avoid at all costs.

The exit seats at row 39 are better than at 24, with more space and further from the door. Still no window and there is a galley and lav there so you might have to balance space with noise concerns.

The center bulkhead seats at rows 24 and 40 have good foot room. It is maybe a couple inches shorter than being able to extend feet fully under a row in front but not significantly truncated like many bulkhead rows can be. Of course, these are also bassinet locations so odds of being swapped out or next to a baby increase with that selection.

At the very back of the plane the fuselage narrows, leaving two rows with pairs on the outside rather than triples. The forward of these two rows is a decent option for a couple without E+ access. The rear row has an offset window and no overhead bin space. The center of rows 51 & 52 at the very back are also lacking overhead bin space due to the flight attendant rest bunks overhead.

The rows at the rear of the cabins (22, 37, 51/52) offer full recline though for 37 & 51/52 noise due to lav/galley proximity is a concern.

The underseat space in the middle of the economy section has many challenges

The center column of 4 seats presents several challenges for coach passengers. The double middle seat is annoying, of course, but that is exacerbated by having only one of the narrow armrests to fight over. And, just like the aisle seats on the outside blocks of seats, the space is slightly narrower than middle or window seats. But the mounting bars that hold the seats to the fuselage may prove to be the biggest problem for passengers in these seats.

The company sent a notice to FAs noting that “there is only under seat storage for three of the four seats” but that’s not even the worst part. For passengers in the aisle seats the space between the riser and the protective railing is under four inches. That means a foot won’t slide in to that space so both feet have to go “inside” the riser. That will be uncomfortable on a longer trip and also reduce bag storage space. From a passenger comfort perspective this is a most unfortunate design.

  1. Did you happen to measure the width of the Business Class footwells? Curious how the Bulkhead compares to the Straight and to the Angled.

    1. I did measure them. The bulkhead is 20″ wide. The straight is 16″ wide and the angled is also 16″ wide, but it is only full width to 8″ depth and tapers from there so the last 10″ of the bed length is tapered on those seats.

        1. The “good” window seats are the straight ones (odd row numbers). Then there are the angled ones (even row numbers).

  2. I will just avoid flying united at all times. Especially in coach the 31″ seat really doesn’t appeal to me being 6′ 2″ tall. And the width of seats doesn’t appeal to me either. My opinion of the whole design is not good at all from a Pax Ex view

  3. Thanks for this post and the info on FT.

    Not an aircraft I aspire to fly in coach, ever, unless and until they introduce Premium Economy.

  4. One of the most useful posts from any blogger about the 77W, most of whom are just parroting marketing fluff. Thanks and kudos.

  5. Oh, I just noticed that economy seats are those plastic-impregnated “leather” that doesn’t allow you to breath. Most uncomfortable for the 14 hour flights these planes are going to do. Ouch!

  6. The coach seats are a horror. Tall people take aisle seats to make life tolerable. Now we can’t put feet in front of us? And some jerk will insist on a full underseat space next door leaving nothing. Special level of hell for whomever at UA designed this.

  7. Seth, thanks for the unvarnished truth…like Oliver, above, I will avoid this aircraft at all costs unless I spring for Business. Those new “slimline” seats, which they also have on Alaska, are just AWFUL…I flew to Hawaii on Alaska, and thank God I brought a folding gel seat cushion with me. What fresh hell has United concocted for its poor Economy passengers??

    1. The UA seats are not the same as the AS seats, FWIW. Not saying they’re spectacularly better or that you should rush out to fly on them. But it is a different product from a different vendor delivering a different feel.

  8. Thanks for all the details, this is great!
    I like the Business class seats, looking forward to trying it out.
    But I’ll make sure to avoid Economy on this plane at all cost, aweful. I’m tall and an aisle-kinda-guy, but this legroom is too limited. And I don’t like leather seats for long-haul flights, they don’t breathe…

  9. Coach is ridiculous. And even while the very cramp AA or AC (one version) 77W also have 13 rows of window seats in the aft cabin just like UA, both have THREE rows of 2-2 seats, but UA only has TWO rows, adding two more seats than AA/AC have.

  10. TL;DR summary: if your seat is in row 19 or higher, switch to another flight.

    Though…Options for anything other than 10-abrest 777 seem to be dwindling.

  11. Thanks for the detailed description of the back cabin which is all too often overlooked by bloggers. Rather distressing to read this report. It’s not bad enough that UA pretends to have 1-2-1 seating (and distorts the seat map accordingly) when it’s still a 2-4-2 layout in business, the economy cabin is incomprehensible in its leg space treatment of middle bank aisle seats. Definitely a plane to stay away from unless booked in C, which I will admit is a moderate improvement over the sardine can seating that sent me over to the competition after almost a decade as a 1K.

    1. It is 1-2-1 from an access perspective. And any given pair of rows takes up the same amount of space as an angled/herringbone arrangement that is called 1-2-1. The difference is minimal at best.

  12. With the tight squeeze on some window seats, how were the FAs dealing with it for drink and food service?

    Isn’t 10 across the future for the 777s?

  13. Jason’s seat sure doesn’t look comfortable. The extra leg room is not worth the awful seat. It is awesome you got to travel on that media flight. What are your thoughts on the wine tasting they offer? I think it is a cool new addition.
