A £10 million redevelopment of the terminal at Doncaster Sheffield airport has been outlined.
The work will see an expansion of the retail food and beverage offering, new gate bridges and an expansion of the arrivals hall and security search area.
Many of the proposed improvements should be completed for summer 2021.
The scheme is a key part of the a 20-year masterplan which projects passenger numbers to reach 1.45 million this year and to double within the next five years.
The Yorkshire airport ultimately hopes to bring an East Coast Mainline station into the site, enbaling the public transport catchment area to reach around nine million people within a 90-minute travel time.
This would be equivalent to the catchment of Manchester airport utilising existing runway capacity capable of handling 25 million passengers.
If successful, Doncaster Sheffield would be only the second airport in the UK to have direct mainline rail access, with a scheme claimed to be deliverable within the next five years.
New destinations of Cancun, Mexico and Cape Verde will be served this summer with Tui basing a fourth aircraft at the airport.
Airport chairman Robert Hough said: “Doncaster Sheffield airport already boasts a modern purpose-built terminal building facility involving over £100 million of investment just 15 years ago.
“It is so important that as we grow, we continue to maintain our award-winning passenger experience.
“Today’s announcement follows £3.5 million invested to create additional parking spaces to keep up with customer demand and £2 million investment in our on-site solar farm that will generate 25% of the airport’s energy.”
Aviaition minister Paul Maynard added: “Doncaster Sheffield is an award-winning airport and these enhancements will make the passenger experience even better, as it provides a vital service connecting communities and business across the UK.
“We are absolutely committed to enhancing regional airports and air services and our regional air connectivity review will help deliver on the prime minister’s pledge to level up the whole of the UK economy.”
