United Airlines Boeing 737-700 Seat Selection Guide (2026)
✈️ Quick Verdict
United's Boeing 737-700 (fleet types 73G and 73R) seats 126 — 12 United First in 2-2 and 114 United Economy in 3-3, of which 36 are Economy Plus. Across all 41 aircraft there is one seat map, which is unusual for United.
Best seats: 21A, 21C, 21D and 21F — the overwing exit row at 39" pitch. Then 8A/8F, 7C/7D and 2A/2F in First. Avoid 10A and 10F, sold as Economy Plus window seats with no window at all, plus rows 32 and 34.
No seat map lottery — but two cabin lotteries
Where United's A319, A320, 737-800 and 737-900ER all split into competing sub-fleets with different seat counts, the -700 gives you the same 126-seat map every time. What varies is what is in the seat, not where the seat is.
1. The screen lottery
Most 737-700s have seat-back AVOD — a 13" touchscreen in First and 10" in Economy. A minority do not, and on those you are streaming to your own device with nothing to prop it against in standard Economy. Row 7 is the tell: even on screen-equipped aircraft, the row 7 screens live inside the armrest because of the bulkhead in front.
2. The WiFi lottery
| System | Share of fleet | Real-world speed | What you can do |
|---|---|---|---|
| Thales FlytLIVE | ~63% | 25–100 Mbps | Video calls, streaming, real work |
| Viasat Ka-band | ~32% | 10–40 Mbps | Browsing, light streaming |
| Starlink | Rolling out | 40–200 Mbps | Everything, gate to gate |
Starlink is free for MileagePlus members and is being fitted across the 737 fleet, so the Viasat aircraft are gradually becoming the best-connected ones. Until the rollout reaches this sub-fleet in full, connectivity is luck of the draw. Note too that the -700 is on the way out, retiring alongside the A319 and A320 as MAX deliveries arrive — which means short-notice swaps onto one at peak times.
United First — rows 1 to 3
12 Safran cradle recliners · 2-2 · A, B | E, F. 37.6" pitch, 20" wide, 5" recline, 110V AC and USB-A, and a 13" seat-back screen on most aircraft. There is no row 4, 5 or 6.
✅ Best: 2A and 2F — two windows each, clear of the forward galley and lavatory, with a proper footwell and underseat storage. 3A and 3F are a close second and the furthest from galley noise.
Row 1 looks like the premium row and is not. There are no footwell cut-outs at the forward bulkhead, nothing can stay at your feet for taxi, takeoff and landing, and you sit directly behind the galley and lavatory. Fine seats — just not an upgrade over row 2. Every aisle seat here has an adjustable armrest and every seat a personal air vent.
Economy Plus — rows 7, 8, 10, 21, 22, 23
36 seats. Standard Economy Plus is 34" pitch against 31" behind, with 3" recline instead of 2". Power and USB-A are fitted here; standard Economy has none.
✅ Best: 21A, 21C, 21D, 21F — the overwing exit row at 39" pitch, five inches more than the rest of Economy Plus and eight more than standard Economy. Then 8A and 8F (best conventional E+ windows) and 7C and 7D, where the partial-height bulkhead stops short of the aisle and leaves real foot space.
🚫 Avoid: 10A and 10F have no window — a solid section of fuselage wall where the window should be, still sold as Economy Plus window seats. Also weigh up 7A, 7B, 7E and 7F: nothing at your feet for takeoff and landing, and the tray and screen live in fixed armrests, so you gain legroom and lose width. And every middle seat stays a middle seat, even at 39" in row 21.
| Row | Pitch | Notes |
|---|---|---|
| 7 | 34" | Bulkhead. No underseat storage. Tray and screen in fixed armrests. 7C/7D get extra foot space. |
| 8 | 34" | The best all-round Economy Plus row. |
| 10 | 34" | 10A and 10F have no window. |
| 21 | 39" | Overwing exit row. Best legroom on the aircraft. |
| 22 | 34" | Solid. Single-window alignment at 22A/22F. |
| 23 | 34" | Last Economy Plus row. Two windows each at 23A/23F. |
United Economy — rows 11 to 34
78 standard seats · Collins Pinnacle slimlines · 3-3. 31" pitch, 17" wide, 2" recline, no power outlets. Rows 13, 14, 16 to 20 and 33 do not exist, so the cabin is shorter than the row numbers imply.
✅ Best: 11A and 11F for the front of the cabin with two windows each, and 26A, 26F, 28A and 28F for the best window alignment in the rear — on a 737 the seats and windows drift out of phase as you move aft, and these four land squarely on a window. 15C and 15D are the only two seats in row 15 that keep full recline.
🚫 Avoid: row 34 entirely — last row, limited recline, two lavatories and the aft galley behind, and 34A/34C/34D are slightly narrower. Row 32 entirely — immediately ahead of the rear lavatories, with 32D narrower than standard. Row 31 is the warning row: the lavatory queue forms right behind you. 15A, 15B, 15E and 15F cannot fully recline because the overwing exit behind must stay clear.
Quick-pick summary
| Traveller | Pick | Why |
|---|---|---|
| Tall / legroom priority | 21C or 21D | 39" exit-row pitch, aisle access, no bulkhead |
| Solo, wants a view | 8A, 8F, or 26A/26F on a budget | Best window alignment at each price point |
| Couple | 21A + 21B, or 8A + 8B | One middle seat, but the best pitch on the jet |
| Family of three | Rows 24–29, one side of the aisle | Whole row to yourselves, clear of lavatory traffic |
| Wants to work | 7C or 7D | Extra foot space, power at the seat, aisle access |
| Budget, no extras | 11A, 11F, 12C, 12D | Front of standard Economy, off the aircraft quickly |
| Nervous flyer | 21A–21F | Over the wing, least movement felt |
| Absolutely avoid | 10A, 10F, rows 32 and 34 | No window, or lavatory and galley |
How to tell what you are getting
The seat map will not tell you which cabin variant you are on, because the map is identical fleetwide. Instead: check the amenities list for your specific flight for seat-back entertainment and the WiFi provider (Starlink is flagged separately and is free for MileagePlus members). On board, the giveaway is row 7 — if the screens are in the armrests rather than the seat-backs, you are on a screen-equipped aircraft.

FAQ
What are the best seats on United's Boeing 737-700?
Row 21 — specifically 21A, 21C, 21D and 21F. It is the overwing exit row at 39" pitch, five inches more than the rest of Economy Plus and eight more than standard Economy. In First, row 2 is the pick.
Which seats should I avoid on the United 737-700?
10A and 10F, because they are sold as Economy Plus window seats but have no window at all. Then rows 32 and 34, which sit against the rear lavatories and galley, with limited recline in row 34.
Does the United 737-700 have seat-back screens?
Most of the fleet does — 13" in First and 10" in Economy — but not all of it. On aircraft without screens you stream to your own device. Check the amenities list for your flight before you fly.
Is Economy Plus worth it on the 737-700?
In row 21, yes without question: 39" pitch on a 31" aircraft is a real difference, plus power at the seat. Rows 8, 22 and 23 are a reasonable 3" gain. In row 7 you trade width for legroom, and in row 10 the window seats have no window.
How many seats does the United 737-700 have?
126 in total: 12 United First in 2-2 and 114 United Economy in 3-3, of which 36 are sold as Economy Plus.
Are all United 737-700s the same inside?
The seat map is, which is unusual for United. All 41 aircraft have the same 12/114 layout and the same 36 Economy Plus seats. What varies is seat-back entertainment and which of three WiFi systems is fitted.
