UK air-navigation service provider NATS has handled approximately 206,000 flights in June, marking a 2.4% increase when compared with the same period in 2013.
Of the 15 airports where NATS operate air traffic control, a total of ten airports have recorded a rise in scheduled traffic.
Airports that reported the highest traffic include Cardiff with a rise of 13.2%, followed by Farnborough with an increase of 9.4% and Stansted with more than 8.8% rise.
The airports in France and Belgium have reported the highest daily traffic figure to date with 1,564 movements, after implementing measures to reduce the effects of industrial action.
NATS operations managing director Martin Rolfe said: "Last month saw disruption due to the industrial action in France and Belgium, which led to an inevitable traffic increase for us as we continued to work as normal.
"Alongside this, we have handled the increase in scheduled traffic and once again kept delays to a minimum."
