The new Accor-operated hotel is part of a $182 million (£136 million/€161million) development programme known as Bud 2020.

The first phase of this development is scheduled for completion in 2020, in time for football's UEFA European Championships, during which Budapest will host three group games and one round of 16 tie.

The work will also include increased check-in desks, enhanced security facilities and a direct rail link to the city centre.

“With the new airport hotel, we continue to enhance the profile of Budapest Airport and strengthen our competitiveness in the region," said Jost Lammers, chief executive officer of the airport.

"The record two-digit growth of the last few years, which also continues this year, makes the timely implementation of this hotel project even more crucial."

The second phase of the development will conclude by 2024, ensuring that it will already be in use should Budapest win the right to host the Summer Olympic and Paralympic Games after Tokyo 2020.

The second phase will include a new aeroplane "pier", a multi-level parking facility and the expansion of the passenger plane apron area.

The airport, named after the famous 19th century Hungarian composer, is home to 44 airlines, which transported 10.3 million passengers to 95 airports in 36 countries last year.

Last weekend, Budapest’s airport staged the air transport industry’s annual "premier charity sporting event” titled Runway Run 4.0. 

Around 1,000 aviation industry staff competed for a number of titles in the event, supporting the bone marrow transplant charity Anthony Nolan and Hungary’s Suhanj! Foundation, a charity which supports the inclusion of disabled people in sport.

Two Hungarian Olympians were in attendance to set the pace at the event and join in.

Gabriella Szabó and Kinga Bóta, both Olympic medal-winning sprint canoeists, ran with the Budapest 2024 entrants.

“We are very proud of all our competitors for their part in making this a record-attended runway run,” Lammers said.

“Close to 1,000 runners from across the international aviation community took part helping to promote our airport and this fantastic city while allowing us to donate 100 per cent of entrance fees to the benefiting charities."
