KLM is to resume operations between Belfast City Airport and Amsterdam Schiphol from August 3.
The service will operate on an Embraer 175 aircraft carrying 88 passengers.
KLM flights from Belfast City were suspended at the end of March as the carrier reduced its global network to 5% of its usual routes in April and May.
Benedicte Duval, general manager for UK & Ireland, said: “2020 is an important year for KLM and our partners at Belfast City Airport as we celebrate five years of operation.
“Having first launched the route back in May 2015, we are delighted to be in a position to welcome our Northern Irish customers back on board, despite the recent challenges for our industry. The resumption of the daily service between Belfast City and Amsterdam is testament to our long-term commitment to the region.”
She added: “As borders reopen and travel restrictions begin to ease, safety is a prerequisite for KLM as we gradually resume travel and as we all adapt to this new environment, I can assure you that all KLM staff, both on the ground and on board, are committed to guaranteeing our passengers the highest levels of health & safety.”
Katy Best, commercial director at Belfast City Airport, said: “KLM resuming its service from Belfast City in August is really positive news. This year celebrates the fifth anniversary of our partnership with KLM and the Amsterdam route which has performed very well.
“This route provides additional choice for our passengers who may be looking to plan a short break in the Netherlands or indeed to one of KLM’s onward connections.”
KLM says it expects to operate 80% of its normal number of European destinations and 75% of intercontinental destinations in July, increasing to 95% and 80% respectively for August.
However, 50% of intercontinental flights are currently cargo-only.
