Whilst flying is often the quickest method to get to the most popular holiday destinations, tourists can still spend many hours up in the air to reach more exotic travel spots.

One of the longest direct flights that Brits can take spans from London Heathrow to Buenos Aires, the capital of Argentina.

Spanning more than 6,900 miles, the journey takes passengers over the North Atlantic Ocean, over the equator and across Brazil before landing in the popular Argentinian city.

In all, the journey typically takes a considerable 13 hours and 15 minutes to complete, making tourists who leave the UK at 12-noon will arrive in Argentina at 9pm that evening.

In comparison, flights that require a stopover during the journey, typically in Rio De Janeiro often take between 16 and 23 hours to complete, depending on the amount of time required for the connection.

The London to Buenos Aires journey typically takes place three times per week and is operated by British Airways on a range of Boeing 787-8s and 787-9s, known as Dreamliners.

As a result, these journeys can typically carry either 214 or 216 passengers, depending on the model, in addition to flight attendants.

This particular type of plane is used widely for long-haul flights as it is 20 percent more economical than most other models, meaning it is able to travel considerably further without needing to be refuelled.

Upon arriving in Buenos Aires, one of the most impressive attractions to visit is the distinctive La Boca, a neighbourhood featuring colourful buildings and narrow, walkable streets.

Culture lovers will also appreciate the Museo Nacional de Bellas Artes, a gallery housing an impressive collection of paintings and sculptures from local and international artists alike.

Finally, the city is widely renowned for its live tango performances that can be found in many of the capital’s theatres or via street displays in some areas.

Whilst the journey from London to Buenos Aires is considerably longer than most, it is not the longest direct flight that passengers can take.

Currently, the longest distance that travellers can cover without taking a stopover goes from London to Perth, the capital of Western Australia.

The flight, operated by Qantas once per day, spans more than 9,000 miles and takes an average of 16 hours and 45 minutes to complete.
