Direct flights from Philadelphia to London operate at least three times a day, served by two airlines – American Airlines and British Airways. All flights depart from Philadelphia International Airport and land at London Heathrow Airport, usually Terminal 3. Heathrow Airport is the United Kingdom’s largest airport, with easy access into the heart of the city via the Heathrow Express or the Picadilly Line. All flights depart in the evening, with the earliest flight departing at 18:40 and the latest flight departing at 23:00. We’ve compared the best flight below, taking into consideration price, duration, flight amenities and sustainability. 

British Airways 

British Airways offers the cheapest direct flights between Philadelphia and London. It also offers the earliest departure time, making it the best flight for business travellers looking to squeeze in a full day after the journey. Since March 2020, the earlier flight uses the Airbus A350-1000, while the later flight uses the Boeing 787 jet aircraft. The Airbus A350 is one of the most fuel-efficient aircraft operating in the world today, generating 718 KG CO2 per person. The cheapest, and most restricted seats, don’t include hold luggage and you’ll need to pay to select your seats. At the other end of the spectrum, the new Club Suite offers luxurious bedding from the White Company, personalised service and a restaurant-style dining experience. It is the only flight that operates a first-class service. All flights include WiFi and a hot meal. 

Flights depart at 18:40 daily and at 22:00 on Monday, Friday and Sunday. Prices start at $590. Book at BritishAirways.com

American Airlines 

American Airlines offers a marginally more expensive, but more frequent direct service between Philadelphia and London. The flight uses the Boeing 787 jet aircraft, which generates 880 kg CO2 per person. Finnair, British Airways and Iberia also sell this flight. Travellers have three tiers of seating to choose from, with four ticket prices – Economy Basic, Main Cabin, Premium Economy and Business. Like the British Airways flight, if you’ve selected the basic fare you’ll need to pay a fee for a checked bag. There is no first class option on this flight, but Business does offer a separate check-in experience, two pieces of luggage in hold and life-flat seats. This is the best option for travellers looking to travel late at night. 

Flights depart at 19:20 and 23:00 daily and take 7 hours 10 minutes. Prices start at $620. Book at AmericanAirlines.com
