Carrier Targets 5% Growth in Long-Haul Operations Despite Heathrow Slot Constraints
LONDON — British Airways is set to expand its long-haul network with six new routes between July 2026 and January 2027, increasing its international footprint from London Heathrow and London Gatwick airports as demand for global travel continues to recover.
The airline, a member of the oneworld alliance, plans to operate an average of 94 daily long-haul departures from its two London hubs between July 2026 and March 2027. The expanded schedule represents a 5% increase compared with the same period a year earlier, according to industry data.
The growth is particularly notable given the ongoing shortage of takeoff and landing slots at Heathrow, one of the world’s busiest airports. By adjusting frequencies and optimizing its route network, British Airways has managed to increase long-haul operations from Heathrow by 6% despite those limitations, according to aviation industry publication Simple Flying.
Six Routes Added Across Heathrow and Gatwick
British Airways will divide the six new services evenly between Heathrow and Gatwick. While two of the routes involve transferring existing services from Gatwick to Heathrow rather than introducing entirely new destinations, the changes mark new airport-specific additions to the airline’s network.
The planned routes include:
Heathrow–Orlando Returns
Flights between Heathrow and Orlando International Airport will resume on July 21, 2026, with three weekly Boeing 777-200ER services. British Airways last operated the route in 2022. The service will complement the airline’s existing Gatwick-Orlando operation and is expected to run primarily during the United Kingdom’s school holiday period.
The addition will increase competition on the route, joining existing services from Virgin Atlantic. Together, the two carriers are expected to offer up to three daily departures between Heathrow and Orlando during peak summer months, matching the highest frequency ever recorded on the route.
Colombo Rejoins the Network
British Airways will return to Sri Lanka on October 23, 2026, with three weekly Boeing 777-200ER flights from Gatwick to Colombo.
The carrier last served Sri Lanka in 2015, when flights operated alongside services to Malé in the Maldives. The new route will be offered as a standalone service, reflecting renewed demand for travel between London and Colombo.
Gatwick-Barbados Service Restored
On October 25, 2026, British Airways will restart daily Boeing 777-200ER flights between Gatwick and Barbados.
The airline last operated the route in 2024. Combined with existing Heathrow-Barbados services, British Airways expects to offer up to three daily flights to the Caribbean destination, the highest level of service on the route in more than three decades.
Heathrow Gains Costa Rica and Tampa Services
San José Moves to Heathrow
Among the network changes, the relocation of flights to San José, Costa Rica, may be the most significant.
Beginning October 25, 2026, British Airways will transfer its Costa Rica service from Gatwick to Heathrow, operating five weekly Boeing 787-8 flights. The move will make Heathrow the first airport in the United Kingdom to offer scheduled direct flights to Central America from the country’s primary international gateway.
The route previously operated three times weekly from Gatwick using higher-capacity Boeing 777-200ER aircraft configured primarily for leisure travelers. The switch to Heathrow will see the airline deploy the smaller 204-seat Boeing 787-8, which includes a larger proportion of premium seating.
Industry data indicates British Airways carried 34,701 round-trip passengers between Gatwick and San José in 2025, with an average load factor of 79.2%. Heathrow’s larger passenger base and stronger connecting traffic opportunities are expected to improve performance and support higher yields.
Tampa Also Transfers to Heathrow
British Airways will also move its Tampa service from Gatwick to Heathrow beginning October 25, 2026.
The route will operate five times weekly using Boeing 787-10 aircraft. The shift comes as the existing Gatwick-Tampa route has reportedly recorded the lowest load factor among the airline’s U.S. services.
By relocating to Heathrow, British Airways aims to attract more connecting passengers and improve overall route profitability.
Melbourne Returns After Two Decades
British Airways will further expand its Asia-Pacific network with the launch of daily Heathrow-Melbourne flights via Kuala Lumpur beginning January 8, 2027.
The service will be operated by Boeing 787-9 aircraft under fifth freedom rights, allowing the airline to carry passengers between Kuala Lumpur and Melbourne.
The launch marks British Airways’ return to Melbourne for the first time since 2006, when the airline operated Boeing 747-400 flights through Singapore.
Strong Demand Supports Colombo Expansion
The return to Colombo reflects growing demand in a market that handled approximately 362,000 round-trip passengers from London last year.
More than half of those travelers flew via connecting hubs in the Gulf region. Industry observers note that ongoing geopolitical tensions in the Middle East have led some travelers to reconsider connecting itineraries through major Gulf airports.
For the upcoming winter season, British Airways and SriLankan Airlines are expected to operate a combined 12 weekly nonstop flights between London and Colombo. British Airways will offer three weekly services from Gatwick, while SriLankan Airlines will operate nine weekly flights from Heathrow using Airbus A330-300 aircraft.
According to Cirium data, the combined schedule matches the highest number of nonstop flights ever offered between London and Colombo, underscoring growing confidence in long-haul demand and British Airways’ strategy to expand despite capacity constraints at Heathrow.
