People in north-west England who own property in Bulgaria are being targeted by low-cost airline easyJet.
The budget carrier has confirmed that later this year, it will begin offering passage between Manchester Airport and Sofia.
This will help open up the Bulgarian capital to leisure travellers in the north-west, a development which could lead to more people choosing to visit the city.
However, easyJet also believes that the route will be useful for many foreign property investors, as Bulgaria is currently a very popular location among this group.
The airline commented: "The service to Sofia is ideal for the growing number of second home owners from the region investing in the Bulgarian market."
Passengers will be able to fly between Manchester and Sofia three times a week from December 2008.
This comes after analysts at Amberlamb said a number of strong fundamentals are supporting the Bulgarian housing market, such as the country's growing tourism industry.
Irish low-cost airliner Aer Lingus announced it would start a new twice weekly service between Dublin and Sofia for its winter 2008 schedule, along with new services to Hamburg, Newcastle, Salzburg and Agadir. In addition, the company will increase the frequency of flights to a number of other European destinations, a company media statement said.
Aer Lingus currently operates a flight to the Black Sea resort of Bourgas, which was launched earlier this year.
Enda Corneille, Aer Lingus corporate affairs director, said the new serivce "demonstrates our response to the continued consumer demand across our route network and is further testament to our proposition of low fares and great service," the company statement said.
The new flights are scheduled to start October 28 2008.
