United Airlinesseat guide: economy legroom, best seats & upgrades
United Airlines economy seats pitch from 30" on narrowbody jets up to 31" on widebody routes. Exit rows often unlock more space for free. Here is exactly what to book — and what to skip.
How much legroom does United Airlines economy have?
Every United Airlines aircraft carries a slightly different economy layout. The table below shows pitch, width, seat configuration, and the routes each aircraft type flies most often.
| Aircraft | Economy pitch | Width | Layout | Routes |
|---|---|---|---|---|
| Boeing 737-800 | 30" | 17" | 3-3 | Primary domestic hub-to-hub workhorse (e.g., ORD–DEN, IAH–LAS, EWR–CLE) |
| Boeing 737 MAX 9 | 30" | 17" | 3-3 | Domestic mainline medium-haul (e.g., EWR–LAX, ORD–SFO, IAD–DEN) |
| Airbus A320 | 31" | 17–18" | 3-3 | Domestic US short-to-medium haul (e.g., ORD–BOS, IAD–ATL, DEN–PHX) |
| Boeing 757-200 | 31" | 17.1" | 3-3 | Premium transcontinental (EWR–LAX, EWR–SFO) and select transatlantic (EDI, DUB, LIS) |
| Boeing 787-9 Dreamliner | 31" | 17–17.6" | 3-3-3 | International long-haul (transatlantic/transpacific) + select premium transcontinental |
Premium-cabin pitch varies by aircraft. See the upgrade section below for exact figures.
What are the best seats on United Airlines?
On the 737-800 and 737 MAX 9 (United's most common domestic jets), book Economy Plus exit-row seats — row 21A or 21F delivers up to 38.8\" of pitch with full recline capability, more legroom than First Class seats on the same plane at a fraction of the price. If exit rows are sold out, row 7 window seats (7A/7F) sit in the Economy Plus zone and benefit from an open footwell beneath the First Class bulkhead for extra stretch room.
General rules that apply on any United Airlines flight
- Exit rows — typically 4–8 extra inches of pitch with no seat in front. Often free to select at check-in even when they cost money at booking.
- Bulkhead rows — the most forward-cabin legroom, but tray tables live in the armrest and overhead bins may be pre-assigned to another cabin.
- Window seat for sleep — a wall to lean against and no one climbing past you. Rows near the middle of the plane minimize wing noise and turbulence.
Which United Airlines seats should I avoid?
Last row on every aircraft (no recline, adjacent to rear lavatory and galley — constant foot traffic and noise); the row immediately in front of any exit row (cannot recline at all); 737-800 rows 11–12 window seats (A and C positions — air conditioning ducts fully block the window despite normal pricing); 737 MAX 9 seats 4A, 4B, 5A, 5B in First Class (face the mid-cabin lavatory, expect odors and traffic); 757-200 seats 11A and 11F (no window whatsoever). On the 787-9, avoid row 20 Premium Plus on 787-10 variants (positioned directly behind lavatories).
How to upgrade your United Airlines seat
United Airlines offers 4 cabin tiers above standard economy. Prices below are typical ranges — exact costs shift with route length, demand, and how far in advance you buy.

|---|---|---|---|
| United Economy Plus | 33–34" domestic; 34" long-haul | $29–$299 per segment (complimentary for Premier Silver and above) | Extra legroom (3–5" more than standard economy), seatback IFE screen, priority boarding Group 2, 110V AC + USB-A power |
| United First (domestic) | 37–38" | From ~$99 upgrade (MileagePlus miles or cash); base fares vary widely by route | 2-2 recliner seat, complimentary meals and drinks, Group 1 boarding, 2 free checked bags, wider 20"+ seat |
| United Premium Plus | 38" | $900–$1,500 transatlantic; approximately 30–90% more than Economy Plus fares | 19" wide seat with 6" recline, adjustable footrest/legrest, Saks Fifth Avenue bedding, upgraded pre-order meals, complimentary wine/beer, 2 free 50 lb checked bags, priority check-in and boarding Group 2 |

On most United Airlinesroutes, upgrading at check-in or bidding through the airline's upgrade program costs less than buying at booking.
How much does seat selection cost on United Airlines?
Standard Economy seats from $29 per segment; Preferred seats (closer to front, aisle) from $24 per segment; Basic Economy seat add-on from $15 per segment
Basic economy rule
No advance seat selection permitted. Seat is randomly assigned at check-in (typically rear of cabin). Passengers may pay $15+ per segment to select a specific seat. Even MileagePlus elite-status members cannot use their status to select seats for free on Basic Economy fares — payment is required regardless of status.
