Across all types of routes, airlines are taking advantage of advancements in aerospace manufacturing to begin choosing different types of aircraft for shorter-duration flights. Finding the right balance between route frequency and fuel burn has renewed focus on the sub-100-seat market. Major airframe manufacturers chase larger narrowbody families, all the while several specialist builders remain intensely committed to this essential segment.

This list highlights the key manufacturers actively competing for orders below 100 seats in 2026. From pioneering hybrid-electric platforms to rugged turboprops and state-backed regional jets, these companies provide vital connectivity that the aviation industry cannot afford to miss out on. The following details how five specific players are shaping the future of regional airline networks worldwide and keeping even the shortest and lowest-demand routes running.

Heart Aerospace

Disrupting The Status Quo With Hybrid-Electric Power

Heart Aerospace is challenging traditional regional aviation with its clean-sheet ES-30 airliner. Operating from its new California headquarters, the manufacturer focuses entirely on sustainable short-haul travel, putting all of its energy into trying to revolutionize this area. The aircraft features a specialized wing design with integrated engine nacelles that allow operations on remarkably short runways, matching the ability of older turboprops.

The propulsion system blends advanced lithium-ion batteries with twin sustainable aviation fuel generators to optimize efficiency. This configuration delivers an all-electric, zero-emission range of 125 miles (200 km), plenty of range for short connecting regional carriers. When regional airlines require additional routing flexibility, the hybrid backup system extends the operational envelope up to 500 miles (800 km).

With over 250 firm orders, the project has attracted major carriers like United Airlines and Air Canada. Type certification is targeted for the turn of the decade, promising direct operating costs comparable to 50-seat turboprops. The company completed its full-scale demonstrator, the Heart X1, with a 105-foot (32 m) wingspan, which has already gotten many industry watchers excited about a future in which true sustainable flight could become the norm.

De Havilland

Rugged Legacy Trusted By Many

De Havilland Canada continues to support the global sub-100-seat market through its enduring Dash 8 family. Historically manufactured near Toronto and supported via facilities in Calgary, this high-wing turboprop remains a lifeline for remote destinations. Its rugged landing gear and exceptional short-field performance enable operations where modern regional jets cannot fly.

The current marketplace focuses heavily on original equipment manufacturer refurbished Dash 8-400 aircraft. Rather than building entirely new airframes, the Canadian manufacturer has found immense success upgrading existing platforms for growing airlines. These updated aircraft combine high cruise speeds with lower fuel consumption compared to similar regional jet options.

A recent delivery to the Argentinian carrier Flytec required a 15,500-mile (25,000 km) ferry flight over 40 days to reach South America, proving the global reach of the platform. Airlines praise the type because it serves challenging fields while maintaining a seat capacity of up to 90 seats. This combination ensures that the veteran turboprop remains highly competitive against newer designs.

COMAC

China’s State-Backed Entry Into Regional Networks

COMAC has solidified its presence in the regional sector with the C909, the recently rebranded ARJ21 regional jet. Celebrating ten years of commercial service, this platform has carried over 37 million passengers across more than 860 routes. The state-backed manufacturer designed this jet specifically to handle the harsh, high-altitude environments of western China, where aircraft options from abroad did not fit the bill.

The aircraft accommodates between 78 and 90 passengers in a standard cabin configuration powered by twin General Electric turbofans. Its design includes a supercritical wing developed with foreign aerodynamic assistance, paired with a distinct T-tail layout. Early development faced long delays, and doubts were raised over whether COMAC could viably produce an aircraft that could truly challenge Western rivals. The program became a success domestically, and production has stabilized with around 210 airframes built.

Domestic trunk carriers operate large fleets, but the manufacturer is actively securing orders beyond its borders. Airlines in Indonesia and Laos currently fly the twinjet, and Vietnam’s Vietjet recently signed a lease agreement for ten additional airframes. The international expansion demonstrates how the platform is successfully challenging traditional Western duopolies even as the world’s largest manufacturers continue to dominate globally.

ATR

The Turboprop Efficiency Standard Dominating Island And Remote Routes

France-based ATR remains the dominant leader in the sub-90 seat category, relying on turboprop efficiency rather than raw speed. Its flagship ATR 72-600 serves around 200 airlines worldwide, opening dozens of thin routes annually where regional jets would prove entirely unprofitable due to high operating costs.

The airframe thrives in challenging operating environments, frequently flying to unpaved runways shorter than 4,000 feet (1,219 m). Recent milestones include a fresh certification from Transport Canada, opening the Arctic and northern territories to the modern series, alongside new orders from lessors like Avation for five additional units.

Using advanced Pratt & Whitney PW127XT engines, the aircraft burns significantly less fuel than comparable regional jets. This efficiency translates directly into a 45% reduction in carbon dioxide emissions, making it an essential baseline for operators attempting to reconcile thin-route economic viability with strict modern environmental targets.

Embraer

Capping The Segment With Flagship Jet Capabilities And Production Momentum

Brazil-based Embraer is consistently reaching the upper limit of the sub-100-seat market with its highly successful E-Jets family. The massive Embraer E195-E2 targets mainline operations and seeks to compete with the likes of the Airbus A220, and sitting alongside, the smaller Embraer E175 and Embraer E190-E2 remain the bedrock of regional networks, offering passengers a mainline cabin experience without the dreaded middle seat.

The manufacturing giant recently logged its strongest second-quarter delivery performance in 16 years, delivering 20 commercial aircraft during that three-month period alone. Embraer’s growth coincides well with sustained global demand as airlines scramble to replace aging regional fleets with highly efficient platforms capable of flying routes up to 2,000 nautical miles (3,704 km).

With a firm full-year delivery guidance of up to 85 commercial airframes, the manufacturer represents the pinnacle of modern regional aviation performance. Its ability to maintain robust production lines despite global supply chain headwinds gives it the strength to expand cross-country regional connectivity, keeping it both structurally viable and highly profitable for major network carriers.
