The airline beat off stiff competition to win the coveted award during the ceremony at Battersea Evolution on November 6th.
Commenting on the award, easyJet chief executive Andy Harrison said the award is testament to the "hard work and dedication" of the company’s staff.
"It is their commitment that forms the foundation of our success, which enables us to deliver the best possible service day in, day out," he said.
easyJet announced at the end of October that it would launch a new daily flight between Gatwick and Copenhagen on January 15th next year.
The new route is in addition to the existing Stansted to Copenhagen service, which operates three times daily.
The airline has announced that it wants to increase capacity on the route at the beginning of its summer schedule.
