The carrier was responsible for the reintroduction of flights between Manchester and Stansted after Air Berlin withdrew from the route in October 2007.
From April 7th this year, Eastern Airways will increase its number of services between the airports from three to four each weekday.
Chris Holliday, the airline’s chief operating officer, said that the changes will be welcomed by commuters from the north of England.
Aidan Mooney, head of network development at Manchester Airport, said: "We welcome Eastern Airways’ decision to further expand the Stansted service from Manchester.
"This latest announcement is excellent news for north-west companies with business links and it further enhances our network of domestic services as we continue to provide travellers with a truly comprehensive range of worldwide destinations from Manchester."
People travelling with Eastern Airways from Stansted Airport can make use of a dedicated fast-track security channel.
