Boeing 737 aircraft form the backbone of Southwest Airlines, a distinction that makes it the world’s single-largest 737 operator. To modernize its fleet, the airline has placed its bets on the Boeing 737 MAX series almost exclusively, and by mid-2025, the last older models will have been phased out or retired. An examination of current MAX holdings, delivery windows for 2025 and beyond, and preliminary price figures therefore paints a clear picture of where Southwest is steering its network.
A Strategic Partnership Between Carrier and Manufacturer
Operating a single-aircraft family simplifies almost everything, scheduling headaches, and the never-ending grind of line maintenance. The MAX line furthers that simplicity by trimming fuel burn, shaving emissions, and boosting cabin comfort; those traits already form the core of Southwest’s advertising script. About 250 MAX 8s sit in the ramp and gate slots today, and almost the same number of MAX 7s sit in Denver-based execution folders, ready to replace the older 737-700s the moment they arrive. The first of those MAX 7s is scheduled for January 2026 delivery according to open-air leases and lessor talk.
Projected Boeing 737 MAX Deliveries for Southwest Airlines in 2025
Southwest originally scheduled 86 new Boeing 737 MAX jets for arrival in 2025, but lingering production bottlenecks pushed the estimate down to about 73. That figure remains fluid, as planners keep a close eye on the assembly line and may adjust again before years end. An internal breakdown of monthly commits,
| Aircraft Variant | Expected Deliveries in 2025 | Notes |
|---|---|---|
| Boeing 737 MAX 7 | 44 | Awaiting FAA certification; deliveries to start in 2026 but some may arrive late 2025 |
| Boeing 737 MAX 8 | 21 | Already in service; deliveries continue to replace older 737-800s and expand fleet |
| MAX 7 or MAX 8 | 8 | Flexible delivery of either variant depending on certification and production status |
Southwest continues to monitor Boeing’s production closely and may adjust delivery expectations as the year progresses.
Southwest Airlines Fleet Composition Overview (2025)
| Aircraft Model | Number in Fleet | Seating Capacity | Role in Fleet |
|---|---|---|---|
| Boeing 737-700 | 346 | 143 | Aging workhorse; to be replaced by MAX 7 by 2031 |
| Boeing 737-800 | 204 | 175 | Serves short- and medium-haul routes; gradually replaced by MAX 8 |
| Boeing 737 MAX 7 | 0 (on order 342) | ~138 | Future replacement for 737-700; entry expected 2026 |
| Boeing 737 MAX 8 | 250 | 175 | Core modern fleet; replaces older 737-800s and expands capacity |
Southwest flies only Boeing 737s and plans to keep it that way to simplify training, maintenance, and scheduling. The MAX family now underpins nearly all growth targets and, by extension, the company’s emissions goals.
Pricing Insights for Boeing 737 MAX Aircraft in 2025
List prices for Boeing’s jets have become a formality; actual transaction figures hinge on bulk orders, timing, and tough-minded haggling. Even so, market reports suggest an unflyable range of $50 million to $60 million per frame, and lessors currently tag the MAX 8 at close to $400,000 monthly to give operators quicker capacity.
| Boeing 737 MAX Variant | Approximate Market Price (2025) | Monthly Lease Rate (MAX 8) | Notes |
|---|---|---|---|
| MAX 7 | $99.7 million (new price estimate) | N/A | MAX 7 is the smaller variant, designed to replace 737-700 |
| MAX 8 | ~$55 million (market value) | ~$400,000 | Most widely operated variant; Southwest’s largest MAX operator |
| MAX 9 | $128.9 million (list price estimate) | N/A | Larger variant; limited Southwest orders |
| MAX 10 | $134.9 million (list price estimate) | N/A | Largest variant; not yet in Southwest’s fleet |
The discrepancy between list prices and market values reflects significant discounts and evolving market conditions. Leasing is a common option for airlines to manage fleet capacity flexibly, with monthly lease rates for the MAX 8 around $400,000.
Routes and Fleet Outlook for Southwest Airlines in 2025
The latest batch of 737 MAX jets gives Southwest the breathing room to spread its wings again without worrying about planes sitting idle. By midsummer 2025, well over 75 fresh departures will be on the boards.
Florida is the immediate headline. Southwest plans to roll out four new spokes from Orlando-MCO to Fort Myers, Miami, Sarasota, and West Palm Beach by August 2025. Each leg will operate twice a day, playing to the MAX 8s knack for hops that barely touch an hour on the clock. Travel managers tracking Florida demand have been buzzing about these routes for weeks.
Over in the Hawaiian trades, the carrier is tinkering rather than starting fresh. Frequencies on the Honolulu-Kahului lane will dip slightly, but Las Vegas-Honolulu is gaining extra flights to soak up Sin City holiday business.
Night owls finally got a win. Thirty-three added redeye hops will blanket hubs such as LAX, SEA, and SFO to reach time-sensitive markets like BWI, ORD, and BNA before the workday rings. Sales teams say this tweak fuels the underserved midnight-booking window.
Last, leisure customers in Colorado Springs receive a summer treat. Saturday-only MAX service to Cancun opens on a seasonal basis, giving vacationers a quick run from Pikes Peak sand. Expect that flight to fill well before most return-passenger programs go live.

Summary
Southwest Airlines has doubled down on the Boeing 737 MAX line, signaling a clear intent to modernize its fleet while cutting costs and carbon emissions. Even with Boeing’s persistent delivery hiccups, the Dallas-based operator is counting on roughly seventy-three fresh MAX jets by 2025, headlined by the much-anticipated MAX 7 variant that is slated to replace older 737-700 models starting in 2026.
The carriers’ one-type-fleet philosophy gives it operational simplicity that rivals still struggle to match, and the MAX family engines make more noise and burn less fuel than outgoing types. Pricing whispers suggest a discount well below list for each jet, with the market pegging the MAX 8 around 55 million dollars.
As Southwest opens new corridors both across the United States and beyond, these aircraft will be the backbone of low-fare, dependable flying for the millions who board its planes each year. The updated fleet’s bigger range, lower trip cost, and cleaner burn, in short, let Southwest keep its average passenger ticket cheaper while shrinking its carbon footprint.
