Aer Lingus has cancelled two one-way flights from London Heathrow to Dublin and Shannon today due to capacity reduction at Heathrow.
The airline said it is awaiting further direction from Heathrow to understand the impact on its schedule in the coming weeks.
In a statement, it said it will try to minimise disruption caused to customers. Heathrow Airport has imposed a capacity cap of 100,000 daily departing passengers until 11 September amid a lack of resources.
Separately, industrial action at Bordeaux Airport and Lyon Airport has also led to the cancellation of two return flights tomorrow and one return flight on Saturday.
