Crystal Travel | Travel News | 7 July 2026

British Airways confirms new long-haul flights and airport changes from London Heathrow and Gatwick, covering Sri Lanka, Australia, the Caribbean, Costa Rica, Florida, and Thailand.

British Airways Announces Major London Long-Haul Route Update

British Airways has announced a major update to its long-haul flight network, introducing new routes, one returning service, and several airport switches between London Heathrow and London Gatwick. The changes, which take effect between October 2026 and January 2027, give UK travellers more choice for winter sun, long-haul city breaks and Caribbean holidays, while also reshaping how existing routes operate from London.

British Airways London Gatwick To Colombo, Sri Lanka Flights

From October 2026, British Airways will launch new direct flights from London Gatwick to Colombo, Sri Lanka, operating three times a week. Colombo is the main gateway for UK holidaymakers travelling to Sri Lanka's beaches, tea plantations, national parks and cultural heritage sites. The new direct service adds another long-haul option for travellers planning winter sun breaks or cultural holidays to the Indian Ocean island.

British Airways London Heathrow To Melbourne, Australia Flights

British Airways is bringing back its Melbourne route from January 2027, flying from London Heathrow with a stopover in Kuala Lumpur. The total journey time is approximately 23 hours. The return of this long-haul Australia route will benefit passengers travelling for family visits, business trips, sporting events, and extended holidays across Melbourne and southeastern Australia.

British Airways Costa Rica Route Shifts From Gatwick to Heathrow

British Airways London Heathrow Costa Rica Flight Change

British Airways flights to Costa Rica will move from London Gatwick to London Heathrow from October 2026, continuing to serve San José's Juan Santamaría International Airport. This is an airport switch rather than a new destination, but the move to Heathrow may offer easier onward connections for travellers exploring Costa Rica's rainforests, volcanoes, wildlife reserves and beach resorts.

British Airways London Heathrow Tampa Florida Flight Change

Tampa, Florida, will also shift from London Gatwick to London Heathrow from October 2026. Tampa is a popular gateway for Gulf Coast Florida holidays and family travel, and the move to Heathrow is expected to make connections smoother for passengers travelling onward through British Airways' main London hub.

British Airways London Gatwick To Bangkok, Thailand Flights

British Airways is extending its London Gatwick to Bangkok service into the summer 2026 season, with three weekly flights planned from May 2026. The route has a flight time of around 11 hours and 25 minutes, strengthening BA's long-haul Asia network and giving travellers more flexibility to visit Thailand beyond the traditional winter travel period.

What The British Airways Route Changes Mean For UK Travellers

Overall, these updates give UK passengers more long-haul departure choices, wider seasonal flight availability, and in some cases simpler connections through Heathrow. Whether it's a new direct route to Sri Lanka, the return of Melbourne, extra Caribbean flights, or an airport switch for Costa Rica and Tampa, travellers with upcoming trips should check their departure details closely.
