New British Airways flights for summer 2027 add Kilimanjaro and Zanzibar, non-stop Buenos Aires and extra Cape Town services. Here is what it means.
British Airways has unveiled a significant long-haul expansion for summer 2027, headlined by two new destinations in Tanzania.
The new British Airways flights to Kilimanjaro and Zanzibar arrive alongside a 25 per cent capacity increase across the carrier’s Latin America network, plus extra frequencies to Cape Town and Las Vegas.
Together, they show an airline leaning firmly into leisure-led long-haul growth.
Tanzania Arrives On The British Airways Map
The headline addition of British Airways flights is a triangle routing from London Gatwick to Kilimanjaro and Zanzibar, launching on 29 May 2027 and running until 31 October.
Flights will operate three times a week as BA2163, departing Gatwick on Mondays, Thursdays and Saturdays at 09:05 and landing at Kilimanjaro at 20:20 local time.
The aircraft then continues to Zanzibar, departing at 21:20 and arriving at 22:25.
The return leg leaves Zanzibar at 00:25 on Tuesdays, Fridays and Sundays, reaching Gatwick at 07:55.
A Boeing 777 will operate the route with Club World, World Traveller Plus and World Traveller cabins.
Fares start from £849 return including taxes and fees.
British Airways Holidays is also offering seven nights at the five-star LUX* Marijani from £1,499 per person for selected June 2027 dates, which must be booked by 25 September 2026.
Timed For Peak Safari Season
The operating window looks deliberate for these new British Airways flights.
British Airways says the season suits UK school holidays and the peak safari period, when demand for Tanzania is likely to be strongest.
Kilimanjaro is the gateway to the Northern Safari Circuit, taking in the Serengeti and the Great Migration, the Ngorongoro Crater, Tarangire and Lake Manyara.
It is also the starting point for climbs of Africa’s highest peak. Zanzibar offers white sandy beaches, diving, spice plantations and the UNESCO-listed streets of Stone Town.
Pairing a safari gateway with a beach destination on one aircraft lets a single route serve two distinct holiday types.
A Bigger Latin America Network
From 28 March 2027, London Heathrow to Buenos Aires becomes a daily non-stop service, with an onward tag to Santiago in Chile.
British Airways states that this will be the only non-stop flight between London and Buenos Aires.
Rio de Janeiro also benefits.
The daily service loses its previous onward tag to Buenos Aires and becomes a dedicated route, freeing up more capacity for Brazil.
Heathrow to San José in Costa Rica moves from winter-only to year-round operation, at three flights per week.
British Airways says this adds up to a 25 per cent increase in Latin America flights, measured in Available Seat Kilometres and comparing summer 2026 with summer 2027.
British Airways Flights: More Frequencies On Established Routes
For British Airways flights, there will be more frequencies on established routes.
Heathrow to Cape Town grows to 10 weekly flights in summer, up from seven, while Heathrow to Las Vegas rises from 13 to 14 per week.
In the Caribbean, Gatwick to Barbados, which launches this October, will continue through summer 2027 as a daily, year-round service with onward tags to Grenada, Guyana and Tobago.
Gatwick to St Lucia continues as a direct service four times a week.
Two other long-haul launches are also approaching: Gatwick to Colombo from 23 October, and Heathrow to Melbourne via Kuala Lumpur from 9 January.
What It Means For The Wider Network
The pattern is telling for the new British Airways flights.
Gatwick is increasingly a leisure long-haul base, carrying Tanzania, Barbados, St Lucia and Colombo, while Heathrow keeps the higher-frequency trunk routes to Buenos Aires, Rio, Cape Town and Las Vegas.
Seasonal routes are also becoming year-round.
San José and Barbados both move away from winter-only patterns, suggesting confidence that demand holds outside the traditional peak.
Removing onward tags on Rio and St Lucia points to a preference for dedicated capacity where it is justified.
Neil Chernoff, British Airways’ Chief Planning and Strategy Officer, said the new routes “strengthen our footprint in East Africa” while the wider changes deepen London’s connectivity to key global destinations.
What It Means For Travellers
Buenos Aires travellers gain a genuine non-stop option, removing a connection from a very long journey, which will make passengers more likely to book on British Airways flights.
Rio passengers get more dedicated seats, and San José becomes bookable all year.
The Tanzania flights make a holiday combining safari and beach far easier from London, and Gatwick will suit those living south of the capital.
Extra Cape Town and Las Vegas frequencies add flexibility for choosing travel days during busy summer periods.
Is There Extra Demand For Africa?
The press release publishes no passenger or booking figures, so any conclusion must be drawn from the decisions British Airways has made.
Those decisions point towards growing appetite.
Cape Town is receiving a sizeable increase from seven to 10 weekly flights, which suggests existing demand is healthy.
British Airways is also committing a 777 with premium cabins to Tanzania, implying it expects to fill higher-yield seats as well as economy.
The season is aligned with school holidays and peak safari conditions, and Chernoff’s comments about adding capacity across Africa suggest the carrier sees the continent as a longer-term growth area.
From a tourism perspective, Tanzania’s offering spans wildlife, mountaineering, beaches, diving and cultural heritage, appealing to families, adventure travellers and safari enthusiasts alike.
The demand case looks strong, although the first season will be the real test.
Final Thoughts on the New British Airways Flights…
British Airways flights for summer 2027 show an airline investing in leisure-focused long-haul growth, with Africa and Latin America taking centre stage.
Tanzania is the most eye-catching addition, but non-stop Buenos Aires and extra Cape Town services may prove just as significant.
For travellers, that means more choice and easier access to some of the world’s most sought-after destinations.
