A structural shift is under way, and it is gathering pace faster than most people appreciate. Smaller, secondary airports are growing at rates that many of the world’s most famous hubs would envy. Point-to-point flying on modern, efficient narrowbody aircraft is quietly redrawing the map of where people fly from, and to, and how long it takes them to get there.
The numbers are instructive. Memmingen Airport in southern Germany, which serves a catchment that spans four countries, welcomed 3.69mn passengers in 2025 and had recovered to 214.7% of its pre-pandemic levels, with seat capacity at 217.4% of 2019 figures. Rhode Island’s T F Green International Airport handled 4.3mn passengers in 2025, an 11% increase year on year, and grew its scheduled seat capacity by 10%. It has increased its regional market share by nine percentage points in two years. Clark International in the Philippines recorded 14% passenger growth and 18% growth in flight movements in 2025. Prague Airport handled 17.8mn passengers, up 8.5% on 2024, and launched 46 new routes in a single year, including 24 new destinations. Glasgow secured an additional 1mn seats for 2026 compared with 2025, with 15 new routes.
Compare those figures to some of the legacy megahubs, where slot constraints, infrastructure limits, and the sheer weight of existing operations make double-digit growth structurally difficult. London Heathrow grew by 1% in 2025. Frankfurt managed 2%. The contrast is not accidental. It reflects a rebalancing of where demand is forming and, critically, where new aircraft technology is making that demand commercially viable to serve.
The aircraft at the centre of this story is the Airbus A321 family. With jets in the A321 portfolio with a range of up to 4,700 nautical miles, combined with the lower operating costs of a narrowbody platform, has created a new category of route that simply did not exist five years ago. Airbus describes it as “the perfect route opener with lower risk for point-to-point operations.” That is the language of a brochure. The routes being launched with it are the evidence.
Iberia deployed its A321XLRs on Madrid to Boston, then Madrid to Santo Domingo, to San Juan, to Recife and Fortaleza. These are not routes that a widebody aircraft could operate profitably year-round, but they represent genuine, sustained demand. Aer Lingus launched Dublin to Nashville on the type, a nine-hour flight on a narrowbody jet, and Dublin to Raleigh-Durham from April 2026, operating up to five times per week.
Traffic between Raleigh-Durham and Europe reached approximately 731,000 two-way passengers in 2025. The route exists not because Dublin is a megahub, but because the aircraft makes the economics work at a scale that a widebody would not. American Airlines launched transatlantic service to Edinburgh from JFK in March 2026. American is not serving Edinburgh because Edinburgh is a global transfer hub.
It is serving Edinburgh because the A321XLR makes it viable to fly there directly without filling 300 seats. Aviation Week identified 50 new routes launching in April 2026 alone, many of them enabled by the XLR’s range. The summer 2026 schedule carries routes that were commercially impossible 18 months ago. Carriers in the United States, Germany, France, the United Kingdom, Turkey and Spain are positioning the aircraft on dense business corridors, key leisure markets and secondary city pairs that previously required connections through major hubs.
What this means for passengers is significant. The traditional hub-and-spoke model imposed an invisible tax on travel: Connection time, connection risk, and the inconvenience of routing through a major city you sometimes had no interest in visiting. A passenger travelling from a mid-sized European city to a mid-sized North American city would historically fly to London or Frankfurt, wait, then fly onwards. That model served the airline’s network economics. It rarely served the traveller. Direct routes between secondary cities remove that tax entirely.
The economics work differently at secondary airports, too. Lower aeronautical charges, less congestion, faster turnaround times, and greater appetite from airport operators for incentive programmes to attract new routes all reduce the cost base for airlines. Tokyo Narita introduced a cash-back incentive programme offering up to 130% of landing fees for new routes and incremental off-peak flights during the first three years of operation. That kind of competitive pricing is rarely available at a slot-constrained primary hub.
The broader aviation demand picture supports the trend. Global full-year demand in 2025, measured in revenue passenger kilometres, rose 5.3% compared with 2024, with capacity up 5.2%. That is a healthy, balanced market. Within it, however, the distribution of growth is shifting. Istanbul’s Sabiha Gökçen Airport reported the largest year-on-year capacity increase among the top airports it competes with, growing by 15% in 2025 to reach 28.6mn seats, with capacity now 37% above 2019 levels — outpacing Istanbul’s own primary hub. The pattern repeats itself in market after market. The secondary airport, less constrained, more flexible, more willing to compete, takes the growth.
There are genuine limitations to this model. Seasonality remains a structural challenge at many smaller airports, where demand concentrates sharply in summer or around specific leisure peaks and thins considerably in winter. Infrastructure, ground transport links, and cargo facilities at secondary airports often lag behind what premium business travellers expect. Not every secondary city has the catchment population or corporate demand to sustain year-round, high-frequency service, and airlines have launched and subsequently withdrawn point-to-point routes before. Route announcements are not route permanence.
Nor is the hub model finished. The world’s megahubs handle volumes of connecting traffic that no point-to-point network can replicate. Long-haul intercontinental routes serving thin origin-and-destination markets will continue to depend on hub connectivity to aggregate demand. Dubai, Heathrow, Singapore and Doha are not threatened by the single-aisle jet, point-to-point growth. They are structured around a different, complementary logic.
However, very large hubs will continue to dominate intercontinental transfer flows. Below that tier, the competitive map is being redrawn by aircraft economics, passenger preference, and the appetite of secondary cities and their airports to claim a larger share of a growing market. The airports that nobody talks about are not waiting to be noticed. They are building routes, attracting airlines, and posting growth numbers that the famous names can no longer match. Aviation’s next chapter is being written far from the terminals most people know.
