Thomas Cook Airlines Belgium has contracted Egyptair Maintenance & Engineering to conduct C-checks on its Airbus A320 aircraft.
The Ghent-based branch of the British holiday company operates seven A320s, which are stationed in Brussels.
The agreement with the Middle Eastern MRO provider was made with flexibility in mind as it is not yet clear how the group-wide aircraft replacement programme will affect the Belgian fleet, a spokesman said.
Thomas Cook revealed in December that it would begin a five-year replacement and harmonisation programme in 2012 for its 71-strong narrowbody fleet.
Shortly thereafter, the company ordered 30 CFM International CFM56-powered A320s for its German Condor subsidiary.
This was followed by an order for 12 CFM56-powered A321s in January, which are to be delivered to the group from 2014.
