With a fleet now numbering 810 aircraft in service, the carrier is aggressively pushing forward with its modernization plan: retiring older Next-Generation (NG) 737-700\/800s, taking delivery of new 737 MAX models, and updating its onboard product.<\/p>\n\n\n\n<p>Moreover, the airline is also undertaking significant changes to its route network, seating model, and customer experience, changes that reflect both competitive pressure and changing traveler expectations.<\/p>\n\n\n\n<p>Southwest aims to become an all-MAX operator by 2031, meaning it will phase out its NG fleet entirely. By doing so, it expects to reduce average fleet age, maintenance costs, and environmental footprint. Alongside these fleet shifts, Southwest is rolling out cabins with extra legroom, assigned seating, new routes (domestic and limited international), and schedule realignments. <\/p>\n\n\n\n<p>Below is a breakdown of the carrier&#8217;s current fleet, orders, route changes, and what to expect through the rest of 2025 and beyond.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-1024x576.webp\" alt=\"As of mid-2025, Southwest Airlines (WN)\u00a0continues its legacy as the largest operator of the Boeing 737 in the world.\" class=\"wp-image-76921\" srcset=\"https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-1024x576.webp 1024w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-300x169.webp 300w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-768x432.webp 768w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-50x28.webp 50w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-1600x900.webp 1600w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-1536x864.webp 1536w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-150x84.webp 150w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-450x253.webp 450w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4-1200x675.webp 1200w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/12\/87iiqij4.webp 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Photo: Cl\u00e9ment Alloing<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-southwest-fleet-overview\">Southwest Fleet Overview<\/h2>\n\n\n\n<p>Here is the latest recap of Southwest\u2019s fleet and outstanding orders, plus notes on retirements and upcoming deliveries. All aircraft are Boeing 737 variants.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Boeing 737-700<\/strong>: 334 aircraft in active service. These are the oldest in the fleet by average age (19\u201320 years), and Southwest has committed to phasing them out by 2031. They are being slowly retired quarter by quarter.<\/li>\n\n\n\n<li><strong>Boeing 737-800<\/strong>: 203 aircraft in service. These NG-800 series jets are also part of the transition out as Southwest increasingly uses newer 737 MAX variants to replace capacity. <\/li>\n\n\n\n<li><strong>Boeing 737 MAX 7<\/strong>: No aircraft in service yet; 314 on order. These units are expected to start deliveries in 2026 and will take over much of the function of the retiring 737-700s. <\/li>\n\n\n\n<li><strong>Boeing 737 MAX 8<\/strong>: 273 in service, plus 196 more on order. Southwest is now the largest operator of the MAX 8. These jets are replacing older NG-800s and helping push the airline closer to an all-MAX fleet. <\/li>\n<\/ul>\n\n\n\n<p><span>The total fleet&nbsp;in September stands at <strong>810 in service,<\/strong>&nbsp;with about&nbsp;<strong>510 aircraft <\/strong><\/span><strong><span>on o<\/span>rder.<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"666\" src=\"https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-1024x666.webp\" alt=\"\" class=\"wp-image-69583\" srcset=\"https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-1024x666.webp 1024w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-300x195.webp 300w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-768x500.webp 768w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-50x33.webp 50w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-1600x1041.webp 1600w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-1536x999.webp 1536w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-2048x1332.webp 2048w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-150x98.webp 150w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-450x293.webp 450w, https:\/\/aviationa2z.com\/wp-content\/uploads\/2024\/08\/210619_FreedomOneDAL_Smith_Web_41-source-1200x780.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Photo: Southwest Airlines<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-fleet-strategy-amp-retirements\">Fleet Strategy &amp; Retirements<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Southwest is accelerating the retirement of its 737-700 and 737-800 NG variants.

While the brand\u2019s all-737 identity remains, the mix of older 737-700\/800s is steadily giving way to newer 737 MAX aircraft. With 810 aircraft in service and 510 on order, the replacement cycle is also well underway. <\/p>\n\n\n\n<p>The shift to cabin retrofits, assigned seating, extra legroom, and route network expansion signals that Southwest is adapting to changing passenger expectations and competitive pressures.<\/p>\n\n\n\n<p>By pushing toward 100% MAX-series by 2031, retiring older airplanes, and adding both capacity and service quality, Southwest is balancing cost discipline with investment in customer experience. The route network changes, new destinations, red-eye schedules, and increased frequency support this transformation. <\/p>\n\n\n\n<p>Moreover, passengers flying with Southwest in the coming years should expect newer aircraft, more seating choices, and a broader, more modern route map. Southwest\u2019s evolution seems geared toward being more than just \u201clow cost\u201d, it\u2019s becoming a leaner, more premium-aware, and more globally capable carrier.<\/p>\n\n\n\n<p>Stay tuned with us.
