The short version: Delta Comfort+ on the Boeing 737-900ER is a meaningful step up from Main Cabin: more legroom, earlier boarding, overhead bin space reserved for your row, and modern seatback entertainment—plus fast, free Wi-Fi for SkyMiles members on the vast majority of flights. If you value elbow room, quicker deplaning, and fewer carry-on gymnastics, it’s usually worth the upcharge.
Why this Aircraft + Cabin Pairing Matters
Not all “extra legroom” seats are created equal. On Delta’s 737-900ER (the long-bodied 737 that anchors many of its domestic and near-international routes), Comfort+ layers multiple quality-of-life perks on top of a tangible pitch increase. Pitch—the distance from a point on one seat to the same point on the seat in front—is what your knees notice first. On the 737-900ER, Delta lists Comfort+ at roughly 33–34 inches of pitch and 17.3 inches of width—a clear upgrade over Main Cabin’s 30–32 inches—and combines that with dedicated overhead bin space, earlier boarding, and seatback screens.
Delta’s product pages also show that the 737-900ER fleet features USB and AC power at the seat and Wi-Fi onboard, with layouts varying slightly by sub-fleet version. Translation: You can charge, stream, and work without juggling battery percentages—huge on a transcon or a long day of connections.
The Seat, the Space, the Feel
Legroom & posture. The extra 1–3 inches of pitch in Comfort+ seems modest on paper but feels outsized in practice. Your knees clear more easily; your laptop can open wider; even the tray table dance becomes less choreographed. Because the 737-900ER’s cabin is long, the Comfort+ block tends to sit forward of the wing, which reduces engine noise and speeds up the exit at the end. (Configs differ, but Comfort+ is always in front of Main Cabin.)
Seat design. Width is essentially the same as Main Cabin at ~17.3 inches—this is a narrow-body, after all—but the under-seat storage in Comfort+ is usable for a daypack or purse, and the dedicated overhead space takes the stress out of late boarding. If you hate gate-checking, you’ll love this particular perk.
Recline and workability. The Comfort+ recline is modest; this is still an economy-class shell. The real win for productivity is the trio of seatback IFE, power ports, and Wi-Fi—you can watch, type, and browse without playing “find the outlet” or relying on your phone as a hotspot.
Cabin Tech & Entertainment
Seatback screens + Delta Studio. Expect modern seatback displays with movies, TV, podcasts, and live TV on many frames. Delta advertises personal video on its 737-900ER fleet, with content from Delta Studio. Bring wired earbuds or a pair of Bluetooth if your Aircraft supports it; either way, the baseline is a seatback screen that works and a library that won’t leave you bored.
Wi-Fi (now actually free). As of February 2025, Delta reports that most customers now have access to fast, free Delta Sync Wi-Fi, with expansion continuing across domestic and high-volume international routes. You’ll need to log in with your SkyMiles account; once connected, you can browse and stream at “home-like” speeds on most mainline flights. This is a game-changer for Comfort+, turning “extra legroom” into “extra productivity.”
Power at the seat. Delta lists both USB and AC outlets on its 737-900ER variants. That means you can charge a laptop and a phone simultaneously and avoid rotating devices mid-flight. (Always a good idea to pack a short cable to avoid dangling cords.)
Food & Beverage: What to Expect
Delta frames Comfort+ as a more comfortable economy, not a separate premium cabin. As for the airline’s services, it emphasizes Starbucks® coffee, beer, wine, and spirits (for those aged 21 and up) on flights over 500 miles and premium snacks on flights over 900 miles when there is no meal. You’ll still choose from the Main Cabin’s beverage cart, but the snack basket and service cadence often feel just a notch more attentive toward the front.
Boarding & Deplaning Advantages
Comfort+ boards earlier (Zone 3), and because its rows sit forward of the Main Cabin, you’ll deplane faster, too. Those two time-savers—plus the dedicated bin space—are the subtle, compounding benefits that make Comfort+ feel premium even without a different seat shell.
Layout Notes: How Many rows, where the exits are, and why it matters
Delta operates multiple 737-900ER layouts (you’ll see labels like 739, 73J, or 73R on Delta’s aircraft page). Across them, the consistent truths for Comfort+ are:
- It sits ahead of Main Cabin.
- It offers ~33–34″ pitch and USB/AC power.
- The Aircraft features eight exits and 3–4 lavatories, depending on version, which affects where traffic and galley noise will be.
Consider rows away from lavs and galleys if you’re sensitive to foot traffic. Aim for the first few rows of Comfort+ if you want speed at the door. And if legroom is your north star, the exit row(s) within Comfort+ often stand out—check the exact seat map in your booking because the row numbers shift by sub-fleet.

Best Seats in Delta Comfort+ on the 737-900ER
Pick these if you can:
- Bulkhead rows in Comfort+. Extra knee clearance without someone reclining into you—great for laptop use. Mind the under-seat storage (bulkheads lack it during taxi/takeoff/landing), but your dedicated overhead helps.
- Exit-row Comfort+ seats. You’ll often see the most legroom short of First, with the usual caveats: fixed armrests and sometimes colder temps near the exits.
- Forward-most Comfort+ rows. Minimal aisle traffic, quicker service, first off the plane.
Avoid if you can:
- This is the last row of Comfort+. It’s the transition to the Main Cabin; recline can be limited, and the aisle becomes a walkway for folks using forward lavs.
- Rows adjacent to galleys/lavs. Noise and light spill can chip away at rest on early/late departures.
(Exact row numbers vary by layout; check the live seat map in your reservation for the most accurate view.)
Service Flow & Soft-Product Feel
Because Comfort+ sits forward, flight attendants reach it first in the service sequence. The premium snack selection on eligible flights and the extra bin space make it feel calmer at boarding and tidier mid-flight; fewer last-minute overhead shuffles, fewer aisle blockages. Add free Wi-Fi and seatback entertainment, and a quiet, work-friendly zone even when the cabin’s full.
Value: When Comfort is Worth It
Comfort+ shines when one or more of these is true:
- You’re tall or working on a laptop. The additional pitch converts directly into better posture and usable tray-table angles.
- You carry on, always. The dedicated overhead perk means what you bring stays with you, overhead, not in the jet bridge valet pile.
- You’re time-sensitive. Earlier boarding and a forward location mean less time waiting for space and less time waiting to deplane.
- You need connectivity. On a fleet with fast, free Wi-Fi for SkyMiles members and power at the seat, Comfort+ becomes a legit mobile office.
If the price delta vs. Main Cabin is modest, Comfort+ is the easy choice. If the gap is large and you’re short-hauling under two hours with a personal item only, Main Cabin can be fine—especially on off-peak flights with emptier middles.
Booking Strategies & Upgrade Tips
- Shop the specific Aircraft. Delta’s booking flow shows the exact 737-900ER seat map for your flight. If you see a Comfort+ exit row open, grab it. If not, watch like a hawk—seats churn as elites reshuffle.
- Link your SkyMiles account. You’ll need it to access the free Wi-Fi onboard; logging in takes seconds and unlocks a lot for zero dollars.
- Mind equipment swaps. Operational changes can swap in a different 737-900ER sub-variant. The Comfort+ experience stays broadly consistent, but row numbers and lav locations may shift. Reconfirm your seat after schedule changes.
- Choose timing strategically. Earlier departures and mid-day non-bank flights can see lower Comfort+ buy-ups and better seat availability.

Who Should Pick Comfort on the 737-900ER?
- The pitch, power, and free Wi-Fi trifecta are tailor-made for business travelers and digital nomads for inbox zero and document edits.

Sub-Fleet Notes & Retrofit Variability
Delta’s 757-200s aren’t a monolith. Cabins can differ subtly by tail and retrofit cycle. Expect the same 2-2 First Class layout, but details—power ports, USB type, bin style, seat shrouds, and LED lighting—can vary. If cabin freshness matters, peek at recent seat photos in your booking flow (Delta’s app sometimes shows tail-specific imagery) and scan traveler photos from the past month for that route.
Practical tip: If power at the seat is mission-critical, pre-charge at the gate and bring a compact power bank; don’t let a one-off inoperative outlet derail your workflow.
Booking Checklist
- Fare delta vs. Comfort+: If First costs ≤ 30–40% more than Comfort+ on your dates, it’s usually worth it for seat width + priority.
- Schedule integrity: Prefer morning departures for fewer delays and cleaner Aircraft turns.
- Seat map health: Plenty of open pairs up front? Your odds for quiet + bin space improve.
- Upgrade strategy: High-tier Medallions + off-peak days (Tue/Wed/Sat) = best shot.
- Connection risk: Tight layovers? First, quick deplaning can be the difference between sprint and stroll.

- Cons:No under-seat storage, more galley noise & light, screen can feel slightly farther.
- Who it suits: Minimalists, short flights, flyers who want first on/first off.
Rows 2–3 (Goldilocks Zone)
- Pros:Under-seat storage, less galley/lav traffic, good window alignment on many tails.
- Cons: Few. These are the sweet-spot rows.
- Pick:2A/2F or 3A/3F for privacy; 2C/2D if lav access matters.
Rows 4–5 (Curtain Adjacent)
- Pros: Often easier upgrades here; still comfortable.
- Cons: Slightly more coach bustle after the curtain, occasional scent/footfall spillover.
- Tip: If noise bothers you, avoid the last row unless it’s the only way up front.
Window alignment & sun angle
- On some tails, windows are offset by a half-frame; scan photos or use a seat intel site for your tail history.
- Eastbound mornings: left side (A) minimizes sun; westbound evenings: right side (F) often wins.
