Quite a lot of cancellations thanks to industrial action over France. The strike has been called off but airlines including BA had scrubbed the services and from the ATC report below there is nevertheless reduced capacity over France today. Other airlines such as AF and IB have also cut services. Either way the following will be INDN.
