Contigency planning enabled Monarch Airlines to run a full flight schedule while other carriers cancelled services during the 48-hour French air traffic control strike.
The airline operated its entire flying programme of 136 flights to destinations across Europe with average delays of 39 minutes.
Monarch carried a total of 22,160 passengers over the two-day period.
Head of operations, Andy Parker, said: “Careful planning sessions were held in the days leading up to the strike.
“We are extremely happy with our operation over the past two days; yesterday our flights leaving the UK operated with an on-time performance of 66%.
“After careful planning, which included re-routing various flight paths to avoid French airspace and minimise disruption, we managed to keep to our planned programme.
“Contingency plans were put in place for dealing with any delays and this has resulted in minimal disruption to our customer’s travel arrangements.
“Our decision to run our full planned flight schedule was a huge success enabling us to make sure 22,160 of our customers arrived home or to their holiday destination with minimal disruptions to their travel arrangements.”
Chief executive, Andrew Swaffield, added: “I would like to take this opportunity to thank all of our operations team who kept our flying programme running during the French ATC strike.
“Although out of our control, their hard work enabled us to get our customers to their desired destination experiencing minor delays.
“I am delighted to say that the airline operated 100% of scheduled flights over the past two days.”
