Southwest Airlines Boeing 737-800 Seat Selection Guide (2026)

Southwest's Boeing 737-800 is the airline's workhorse — 207 aircraft carrying 175 passengers each in an all-Economy 3-3 layout. Since January 27, 2026, every seat is assigned and the cabin is divided into three distinct zones: Extra Legroom, Preferred, and Standard.

The vast majority of the fleet has the Heart interior (Boeing Sky Interior, no power outlets). A small number have been retrofitted with the Elevate interior (RECARO R2 seats, USB-A/USB-C power, device holders). The seat advice below covers the Heart layout, which is what you'll most likely fly. The Elevate differs slightly in row 1 and row 15 configuration — see the note at the end.

Quick Verdict

Cabin Overview

The Heart interior features Boeing Sky Interior with curved ceiling panels and LED mood lighting, Boeing Space Bins, and Collins Meridian slimline seats with 4-way adjustable headrests. The key limitation is no power outlets — charge your devices before boarding. Entertainment is streaming-only via the Southwest app on your own device.

A growing minority of 737-800s have the Elevate interior with RECARO R2 seats, USB-A/USB-C at every seat, device holders, and larger bins. If your seat has a charging port, you're on an Elevate. The seat zone structure and advice is the same for both — see the "Elevate Differences" note at the end for the few layout variations.

The Three Seat Zones (Post-January 27, 2026)

Southwest now sells three seat types at booking. The physical seats are identical in all three zones — the difference is pitch (legroom) and cabin position.

Extra Legroom (Rows 1–5, 6ABC + Exit Rows 14–16)

• Pitch: 35 inches — 3 inches more than Standard/Preferred
• Seats: 46 seats (note: Row 1 has only 3 seats on Heart, Row 15 has only 4 seats)
• Perks: Complimentary premium beverages (including alcohol), Wonderful Pistachios snack, earlier bin access
• Boarding: Groups 1–2
• Access: Included with Choice Extra fare; A-List Preferred members select free at booking; A-List members can upgrade free within 48 hours of departure; available as paid upgrade on all other fares

Preferred (Rows 6DEF + 7–13)

• Pitch: 31 inches — same as Standard
• Seats: 45 seats
• Perks: Forward cabin position for faster deplaning, same standard snacks
• Boarding: Groups 3–5
• Access: Included with Choice Preferred fare; A-List members select free at booking; available as paid upgrade

Standard (Rows 17–30)

• Pitch: 31 inches
• Seats: 84 seats
• Boarding: Groups 6–8
• Access: Choice fare gets free Standard seat at booking; Basic fare assigned at check-in (you get what's left)

Best Seats on the 737-800

🏆 1D, 1E, 1F — First to Deplane, Extra Legroom

Row 1 on the Heart interior only has three seats — all on the right side (D/E/F). These are among the best seats on the aircraft: Extra Legroom pitch, first row so you're first off the plane, and the premium beverage service starts here. 1D gets the aisle, 1F gets the window.

The trade-offs: No underseat storage during takeoff/landing, tray table in the armrest (slightly narrower effective width), and proximity to the forward galley/lav. But for most passengers, being first to deplane outweighs these drawbacks.

🏆 2A, 2B, 2C — Extra Legroom Window Side

The left side of row 2 is where 1ABC would normally be — but since those seats don't exist on the Heart interior, row 2 ABC are effectively the first full row on the left side. You get 35" Extra Legroom pitch, full underseat storage, standard tray table, and you're second off the plane. 2A is the prime window seat; 2C is a strong aisle pick.

🏆 16A and 16F — Unlimited Legroom

These two window seats behind the overwing exit have virtually unlimited legroom. There is no seat in front of you — 15A and 15F are deleted entirely to meet FAA exit clearance requirements. You get a standard tray table in the armrest, full recline, and more legroom than any other seat on the aircraft.

The catch: The armrest-mounted tray table makes the seat slightly narrower. And because 16A/16F are classified as Extra Legroom, they require a paid upgrade or status/fare entitlement.

Rows 3–5 (Extra Legroom, Front of Cabin)

Solid Extra Legroom seats with 35" pitch, quick deplaning, and premium service. Rows 3–4 are particularly good for families who want a full row of three together in Extra Legroom.

Row 6 A, B, C (Extra Legroom — Split Row)

6A/6B/6C are the last Extra Legroom seats before the Preferred zone begins. 35" pitch with a standard window seat at 6A. Note that the other side of the aisle (6D/6E/6F) is Preferred with 31" pitch — so this row is split between zones.

14A–14F (Extra Legroom Exit Row — If You Don't Need Recline)

Row 14 has 35 inches of pitch and is designated Extra Legroom, but these seats do not recline because Row 15 is the overwing exit row behind them. For short flights under 3 hours, this is a non-issue. For longer flights, you may want recline.

16B, 16C, 16D, 16E (Exit Row — Reclines)

Unlike 16A/16F with their unlimited legroom, the middle and aisle seats in row 16 have standard-ish pitch. However, the seats in front of them (15B, 15C, 15D, 15E) don't recline, so you effectively get extra usable space. Plus, row 16 middle/aisle seats do recline. Decent picks for aisle passengers who want to stretch.

Seats to Avoid

❌ Row 13 (All Seats) — No Recline

Row 13 is the last row before the overwing exit at row 14. Because of the exit row behind it, no seat in row 13 reclines. It's classified as Preferred (31" pitch) but is genuinely the worst Preferred row. Row 12 reclines normally; Row 14 at least has Extra Legroom pitch to compensate.

❌ Row 15 B, C, D, E — No Recline, Narrower, Exit Row Restrictions

Row 15 only has four seats (15A and 15F don't exist). These four middle/aisle seats have Extra Legroom designation and extra pitch, but they do not recline, have armrest-mounted tray tables (narrower), no underseat storage during takeoff/landing, and fixed armrests. On balance, row 14 is better (same no-recline but without the narrower seat issue).

❌ Rows 29–30 (All Seats) — Last Rows

Near the rear lavatories and galley, limited or no recline, engine noise, and you'll be last to deplane. If you're assigned a Basic fare seat here, it's the airline's way of encouraging you to buy up next time.

⚠️ Seats 10A, 11A, 11F — No Window

These three seats have a misaligned or missing window due to the 737's window placement relative to the fuselage frame. If you specifically want a window view, avoid these. Otherwise they're standard Preferred seats with no other issues.

The Exit Row Deep Dive (Rows 13–16)

This is the most complex section of the 737-800 cabin and where most passengers get confused. Here's exactly what happens at each row:

Bottom line: If you're paying for Extra Legroom in the exit area, 16A or 16F are the clear winners. 14A-F are acceptable for short flights. 15BCDE are the worst exit seats.

Fare & Seat Selection Strategy

If You're on a Basic Fare

You won't choose your seat until check-in. You'll likely end up in rows 22–30. Check in exactly at the 24-hour mark to get the best remaining Standard seat. Target row 17–20 if available — still Standard zone but further from the rear lavs.

If You're on a Choice Fare

You can select any Standard seat at booking. Target rows 17–19 for the best Standard seats (forward of the rear section, away from lavs). You can pay to upgrade to Preferred or Extra Legroom.

If You're on Choice Preferred or Choice Extra

Choice Preferred includes a Preferred seat. Choice Extra includes an Extra Legroom seat. For Choice Extra, immediately target 16A or 16F for legroom, or 1D/1E/1F for fastest deplaning, then 2A/2B/2C.

Elevate Interior Differences

A small number of 737-800s have been retrofitted with the Elevate interior. The key amenity upgrades are USB-A/USB-C power at every seat, built-in device holders, larger pivot-style overhead bins, redesigned tray tables, and RECARO R2 seats with a slimmer profile.

Layout differences from Heart:

• Row 1: All 6 seats exist (1A through 1F) — unlike Heart where only 1D/1E/1F exist
• Row 15: All 6 seats exist (15A through 15F) — unlike Heart where 15A/15F are deleted
• 16A/16F: Still Extra Legroom but no longer have "unlimited" legroom since 15A/15F are present
• All other rows, zones, and pitch measurements are identical to the Heart interior

Best Seats Summary

What Frequent Flyers Need to Know

The new tier system rewards status and fare class, not check-in speed.

Boarding groups: Groups 1–2 cover A-List Preferred, Choice Extra, and any passenger in an Extra Legroom seat. Groups 3–5 cover A-List members, Choice Preferred, and Rapid Rewards Credit Cardmembers. Groups 6–8 are everyone else, with Basic fare last. Active-duty military and purchased Priority Boarding still pre-board ahead of Group 1.

Free seat selection by tier:

• A-List Preferred — any seat, including Extra Legroom, free at booking.
• A-List — Standard or Preferred free at booking; Extra Legroom upgrade window opens 48 hours before departure (if seats remain).
• Rapid Rewards Credit Card — Standard or Preferred free at booking; no complimentary Extra Legroom upgrade.

Bags policy update. Bags Fly Free ended May 28, 2025. Choice Extra and A-List Preferred get two free checked bags. A-List and Southwest credit cardholders get one. Everyone else pays $35 for the first and $45 for the second. Carry-on and personal item remain free for all passengers.

What hasn't changed: no blackout dates on Rapid Rewards redemptions, points don't expire, and family boarding still groups everyone on the same reservation (up to 9 passengers) into the same boarding group.

Frequently Asked Questions

Is Southwest Extra Legroom worth the price?

Extra Legroom uses dynamic pricing — roughly $38–$41 on short flights (Tampa–Fort Lauderdale), $50–$65 on medium routes (Denver–Austin), and $83–$91 on long-haul (Baltimore–Los Angeles). You get 34–35" pitch versus 31" Standard, plus complimentary premium drinks and earlier boarding (Groups 1–2). On flights under 2 hours the difference rarely justifies $40+. On flights over 3 hours, especially Hawaii and transcon, it becomes a much easier call. Before paying, check whether a Choice Extra fare bundles Extra Legroom plus two checked bags cheaper than buying them separately — on longer routes it usually does.

Can I move to an empty seat after boarding?

Officially, no. Southwest is enforcing seat assignments strictly because seats are now sold at different price tiers — letting passengers freely move to Preferred or Extra Legroom would undermine the model. In practice, enforcement varies. Same-tier moves (Standard to Standard) are more likely to be allowed than upgrades. Once the cabin door closes, crews tend to relax slightly. If you need to move for a specific reason — sitting with a young child, for instance — ask the cabin crew before moving yourself.

How do I make sure my family sits together?

Book a Choice fare or higher. Basic fares don't allow seat selection at all — the system assigns seats at check-in and Southwest only "tries" to keep families together, with no guarantee. Select seats immediately at booking. Adjacent seats fill fastest, particularly rows of three. Middle-of-cabin Standard rows are your best bet for a full row together since Preferred and Extra Legroom go fastest. If you're stuck on Basic, check in the moment the 24-hour window opens. As a last resort, gate agents can sometimes reassign seats to keep young children with a parent.

What seat do I get with a Basic fare?

You don't choose. Basic fares are assigned a Standard seat at check-in, 24 hours before departure. You can't pre-select; you can't pay to choose a specific Standard seat. Your only paid options are upgrading to Preferred or Extra Legroom. You'll typically end up toward the rear of the cabin, possibly in a middle seat, boarding in Groups 7–8 (last). If seat selection matters at all, Choice is the minimum fare worth booking.

Do A-List members get free Extra Legroom?

Only A-List Preferred get it guaranteed. A-List Preferred members can select any seat, including Extra Legroom, free at booking. Standard A-List can select Standard or Preferred free at booking, then upgrade to Extra Legroom for free within 48 hours of departure — if available, which on competitive routes it often isn't. Rapid Rewards Credit Card holders get free Standard or Preferred selection but no complimentary Extra Legroom.

Can I change my seat after booking?

Choice and above can change seats anytime via the app, subject to availability. Upgrading to a higher tier requires paying the difference. Basic fares can't change seats at all once assigned, but can pay to upgrade to Preferred or Extra Legroom if available. A-List members can move freely within their complimentary tier. Gate agents can override at the airport for operational reasons or family seating, but don't expect free upgrades.
