British Airways operates a fleet of 59 Boeing 777s , of which 16 are Boeing 777-300ERs. These are some of the workhorses of the fleet, and they are particularly put to work servicing BA's US routes. But while they mostly fly transatlantic, they also fly to other destinations around the world.
Here is where British Airways is scheduled to fly its 777-300ERs in April 2025, according to data provided by Cirium , an aviation analytics company. BA's Boeing 777-300ER United States routes All British Airways 777-300ERs are scheduled to operate out of BA's main hub of London Heathrow Airport with most of the routes being across the Atlantic to the United States . In all, British Airways 777-300ERs are scheduled to operate a total of 722 flights and carry 183,388 seats in April.
In total, British Airways flies to 28 destinations in the United States. It flies to 26 destinations from Heathrow and four destinations from London-Gatwick. British Airways flights from Gatwick are typically leisure routes.
The American routes from Gatwick are to Orlando, Tampa, New York-JFK, and Las Vegas. It also flies to New York JFK Airport and Las Vegas from Heathrow. A total of eleven routes are scheduled for April using 777-300ERs, including a single flight to Malé-Velana International Airport in the Maldives.
Of these, seven are scheduled to operate on routes to the United States. These routes are also scheduled to have on average more flights than routes to other destinations. British Airways Boeing 777-300ER flights to the US in April 2025 Origin: Destination: Flights: Seats: London-Heathrow: New York-JFK 120 30,480 London-Heathrow: Los Angeles 60 15,240 London-Heathrow: Washington-Dulles 30 7,620 London-Heathrow: Chicago-O'Hare 30 7,260 London-Heathrow: San Diego 30 7,260 London-Heathrow: Houston-George Bush Intercontinental 20 5,080 London-Heathrow: Seattle 17 4,318 The busiest April route for the 777-300ER is to New York-JFK, where it is scheduled to operate 120 flights in the month one way, or four per day.
The London-Heathrow to New York-JFK route is notable for many things. It was the first route in the world where an airline (British Airways) generated more than a billion dollars in revenue in a 12-month period. New York-JFK to London was also one of the popular routes for the supersonic passenger jet, Concorde.
Looking back before the age of flying, one can argue the route's predecessor was Southhampton, England to New York, which saw ocean liners like the Titanic. Today, the Queen Mary 2 is the last remaining ocean liner and continues to operate on that route. The next busiest route for the -300ER is scheduled to be to the US's second-largest city of Los Angeles.
BA will be operating a total of 60 flights in the month on that route or two flights a day. Three US destinations will see daily (30 flights in the month) from BA's -300ERs. These include Washington-Dulles, Chicago-O'Hare, and San Diego.
A total of 20 flights are also scheduled to Houston Intercontinental and 17 flights to Seattle in Washington state. BA operates other widebody aircraft on its US routes , including its new Airbus A350s, its iconic Airbus A380 Superjumbos, and all three variants of the Boeing 787 Dreamliner. BA still has all 12 of its original fleet of A380s in service, meaning that it is currently tied with Singapore Airlines for the second-largest A380 fleet in the world.
Emirates is by far the largest operator of the Superjumbo with 116 in inventory, including around eight in storage. The UK flag carrier has a wide range of layouts, particularly on its Boeing 777-200ER jets. BA's Boeing 777-300ER non-United States routes British Airways' 777-300ERs will fly on four non-US routes to destinations in Africa, the Middle East, the Indian Ocean, and the Caribbean.
"The Boeing 777-300 is a long-range, twin-aisle, twin-engine jet manufactured by Boeing, the American aerospace company. We operate these on routes to Asia and North America." - British Airways The only route to see daily flights (or 30 flights in April) is to South Africa's O.
R. Tambo International Airport, serving the city of Johannesburg. That airport is the busiest airport in sub-Saharan Africa and is the primary gateway to South Africa, although Capetown's airport is also significant.
BA also flies to Capetown with other aircraft. British Airways Boeing 777-300ER flights to non-US destinations in April 2025 Origin: Destination: Flights: Seats: London-Heathrow: Johannesburg, South Africa 30 7,620 London-Heathrow: Dubai, UAE 13 3,302 London-Heathrow: Barbados, Caribbean 10 2,540 London-Heathrow: Male, Maldives 1 254 The next busiest route is from Heathrow to Dubai with a total of 13 flights and 3,302 seats. They are dwarfed by the large number of Airbus A380 Superjumbos Emirates uses on that route.
The last two routes are to leisure sun destinations. Barbados is one of the top holiday destinations for British holidaymakers heading for the Caribbean. It is also an exception to the rule that BA operates leisure flights from Gatwick and not Heathrow.
BA is scheduled to operate 10 Boeing 777-300ER flights from Heathrow to the island of Barbados as well as a single flight to the Maldives in the Indian Ocean. British Airways connects the US to London, offering comfortable transatlantic flights on the Boeing 777. British Airways' fleet of Boeing 777-300ERs Looking at data by ch-aviation , all 16 British Airways Boeing 777-300ERs remain in service, with one down for maintenance.
The average age of the fleet is 10.5 years. However, this is unevenly distributed.
The oldest example was built in 2010 and is now 14.8 years old, while the youngest was built in 2020 (delivered in 2021) and is now just 4.3 years old.
They are fitted with the GE90-115BL engine. "The Boeing 777's unique combination of superior range, outstanding fuel efficiency and passenger-preferred comfort has created long-range success for carriers around the world. And the 777-300ER now gives operators a perfect opportunity to extend that success.
Recent upgrades further reduce costs and boost revenue, and the 777's flying experience is still number one with passengers." - Boeing British Airways has some of the oldest 777-200ERs in service. The oldest examples were delivered in 1997, the same year as the first Harry Potter book was published .
The -300ER is the larger counterpart, carrying 392 seats in a typical two-class seating configuration, while the -200ER carries 317. The -300ER is stretched to 242 feet and four inches long (the -200ER is 209 feet and 1 inch). However, the larger -300ER comes with a reduced range of 7,370 nautical miles compared to the -200ER's 8,555 nautical miles.
However, British Airways aircraft are often configured with an emphasis on higher-class seating, meaning that its aircraft are often fitted with considerably fewer seats than Boeing or Airbus' suggested "typical configurations." The -300ER may have a typical configuration of 392 seats - however, BA fits them with just 256 seats, according to AeroLOPA , although Cirium data states 254. That is around 136 seats fewer than the 'typical two-class configuration,' or around the capacity of a typical Boeing 737 MAX.
The -300ER comes with eight first-class suites, 76 Club World business class seats, 40 premium economy seats, and 132 economy class seats. Another example of a low-density British Airways widebody is the Boeing 787-10. That aircraft has a typical two-class configuration of 336 seats.
ANA has the densest configuration, packing 429 seats in it for its short-haul domestic routes in two classes. British Airways has one of the least dense seating configurations of the type,, with only 256 seats across four classes. That is 80 fewer seats than Boeing's 'typical configuration' and 173 fewer seats than ANA's dense domestic configuration.
BA's order for new Boeing 777X aircraft These 777-200ERs are getting older and are expected to be replaced with the modernized Boeing 777X , expected to enter service in 2026. BA has ordered a total of 18 Boeing 777Xs. Boeing currently has a backlog of 559 Boeing 777 family aircraft and an adjusted backlog of 425 aircraft after the accounting adjustment to factor in likely cancelations.
Of these, 481 are for the updated Boeing 777X twin jet . Emirates has by far the largest order for the type having ordered a total of 205 aircraft, followed by its Gulf rival, Qatar Airways, which has an order for 97 of the aircraft. Together, these two carriers account for 302 or 54% of the total orders for the 777X.
"The new Boeing 777X will be the world’s largest and most efficient twin-engine jet, unmatched in every aspect of performance. With new breakthroughs in aerodynamics and engines, the 777X will deliver 10 percent lower fuel use and emissions and 10 percent lower operating costs than the competition." - Boeing Boeing has an overall backlog of 5,528 commercial jets, behind Airbus' backlog of over 8,600 commercial jets.
The upcoming Boeing 777X is Boeing's answer to the popular Airbus A350. Conclusion In conclusion, the bulk of the scheduled BA 777-300ER flights are scheduled to serve US routes. Of these, New York-JFK will see twice as many -300ER flights as the next busiest route.
The -300ERs will operate a total of 11 routes to various destinations. Of these, six routes feature one flight a day or more, and only one non-US route (Johannesburg) will see daily flights..
