Passengers travelling from Gatwick, Heathrow and Luton Airport to French destinations are most likely to experience delays or cancellations as a result of the strikes.
The action is part of a nationwide strike involving other sector workers, protesting against government plans to relax the 35 hour week and other worker benefits.
British Airways has cancelled flights to and from Heathrow, London City and Gatwick airports to France and Spain
“The French Civil Aviation Authority has mandated the cancellation of a number of flights for all airlines using French airspace. Unfortunately, in addition to cancelling some flights to and from France, other European flights which use French airspace will also be affected and are likely to experience delays and cancellations,” said a BA spokesperson.
A spokesperson for easyJet said “Unfortunately even flights not flying through French airspace could be affected, if the aircraft operating the flight has been delayed due to the strike on previous flights.”
“In many cases, we have to push back our aircraft from the gate and then wait on the airfield so that we can take advantage of potential improvements of departure slots.”
The low cost airline Ryanair has cancelled more than 100 flights.
Eurostar trains from London to Paris and Brussels are running normally, and P&O Ferries are confident they will be able to maintain a service on the Dover to Calais route.
