The best-selling widebody jetliner of all time, and one of Boeing’s finest aircraft ever made, the 787 Dreamliner was just approved by the Federal Aviation Administration for a higher max takeoff weight. The increased IMTOW will allow the 787-9 and 787-10 to fly with more fuel to complete longer journeys or carry a larger payload in either passengers or cargo.
The first aircraft featuring the new design elements that will enable this upgrade is now progressing through ticketing and delivery with Boeing and the FAA. America’s aerospace juggernaut, Boeing, says that the update was implemented based on feedback from airlines around the world.
A New And Improved Dreamliner Gives Airlines More Capability
Air New Zealand, the launch customer of the 787-9, will also be one of the first operators to fly a new Dreamliner with the enhanced IMTOW capability ready to go. The way this upgrade is manifested in the 787-9 and 787-10 is thanks to the newer models rolling off the line that are structurally capable of higher weight.
Since December 2025, design refinement has made it possible for -9 Dreamliners to carry 10,000 pounds more than previous models of the same type. Meanwhile, newer -10s are now capable of hauling 14,000 pounds greater weight in fuel, cargo, or passengers.
The network strategy manager, Baden Smith, of Air New Zealand, expressed the carrier’s excitement to receive the first examples that will allow them to fly with additional payload on their ultra-long-haul routes. The airline views the upgraded Dreamliner as an enabler for its network ambitions to support trade tourism and better overall travel connectivity for New Zealand. John Murphy, 787 chief project engineer, also remarked:
“We started this effort after airlines sent Boeing a clear message: they wanted greater flexibility.”
787: The Most Adaptable Airliner Ever Made
Darren Holst, vice president at Boeing, proudly declares that the 787 Dreamliner family of twin-aisle, twinjets is responsible for opening more than 530 new non-stop routes around the world that were never previously served. The 25% greater fuel efficiency that the Dreamliner has over legacy aircraft that it replaced is the key enabler of this stunning growth in travel networks.
As a direct result of that exceptional fuel efficiency, the 787 can fly cheaper and further than legacy twin-aisle. It is even affordable enough to operate that it has replaced narrow body long haul jets on ‘long and thin’ routes to niche destinations with low volume service but steady demand to distant airfields. Similarly, that efficiency has made it a highly flexible aircraft that can serve a wide variety of major hubs and easily switch to seasonal routes as demand fluctuates up and down.
The IMTOW upgrade comes just about 15 years after the Dreamliner debuted in 2011. Since then, the aircraft has revolutionized the world of commercial flying, and more than 1,200 examples have been delivered to customers around the globe. The 787 directly spurred Airbus into driving its A350 next-generation widebody program to full-rate production faster. Its design elements have also served to inspire succeeding Boeing designs like the 737 Max and upcoming 777X.
787-8 Vs 787-9 Vs 787-10: How The Dreamliner Variants Differ
The three 787 variants are tailored to different market segments to fill niches and offer a placement for different previous-generation aircraft.
Boeing’s Bedrock: History’s Most Popular Widebody
The Boeing 787 Dreamliner already has a delivery total that vastly overshadows its competition from Airbus, the A350. At the same time, the backlog is already thousands of aircraft deep, having secured its title as the best-selling wide body of all time. This upgrade will not only further fortify that throne, but it also makes the Dreamliner the most valuable product in the Boeing lineup, and its steady foundation during a turbulent period.
Notably, one of the reasons the A350 has been less popular is that it is a larger aircraft with a higher total capacity. The increased maximum takeoff weight of the Dreamliner will bring the two closer to parity and make the 787-10 more competitive with the A350-900. The enduring popularity of the Dreamliner has seen large orders continue in the past year, with Qatar Airways signing up for 130 units in 2025, while Delta Air Lines finally ordered its first batch of 787s early in 2026.
