More people will start using domestic airlines to get around Britain because it is considered a cheaper option, it has been predicted.
A number of regional airlines have launched flights to domestic destinations, which have proved popular among both holidaymakers and business people.
Cat Hobbs, a public transport campaigner at the Campaign for Better Transport, said that booking flights has become so cheap because the government "has been giving lots of tax breaks to the aviation industry".
"At the same time, the government has been cutting investment to rail so train fares keep rising more and more," she commented.
"That means that, if people can’t afford to take the train, they are going to fly instead."
Regional airline Eastern Airways recently introduced flights to Aberdeen and Southampton from Liverpool John Lennon Airport.
Elsewhere, Air Southwest’s winter schedule includes up to six flights a day between Newquay, Plymouth and London, with four flights operating from Gatwick and two from London City.
In 2006, more than a third (36 percent) of take-offs and landings at UK airports were for domestic flights.
