We are expecting a further period of industrial action by French Air Traffic Control trade unions on the evening of Wednesday 14 September and throughout Thursday 15 September.
This threatened strike action will unfortunately bring more unnecessary disruption for some customers travelling in Europe.
We are sorry that your flight could face disruption, which is beyond our control, and we recognise that you may not wish to travel as a result.
If you are due to travel on Thursday 15 September
We have introduced a more flexible rebooking policy so that you can travel on alternative dates and avoid the main period of strike action.
If you are due to fly to or from any French airport (as well as Madrid and Barcelona) on Thursday 15 September, regardless of whether your flight is operating or not, you can bring your flight forward up to and including Wednesday 14 September or move it back to a date up to and including Thursday 22 September. All rebookings are subject to availability.
Potential cancellations
Unfortunately, if the threatened strike does go ahead, we will have to cancel some flights and other short haul flights may also experience some delays and disruption, given how many flights would normally use French airspace each day.
We will be using larger aircraft, where possible, to help affected customers and are doing all we can to reduce the levels of disruption.
