I will come on to that. As the UK, we have 111 bilateral agreements with the rest of the world in our own right. The noble Baroness is quite right to point out that we have bilateral agreements through our membership of the EU.
The next issue raised on the basis of our expectations, how we are working with EU carriers to make sure that we have no gap in services and the assurances we can give that the CAA has the capacity and resources in place. Our expectation is that EEA carriers would require advance permission before operating to the UK. This is founded on international law. I already spoke about the 1944 Chicago Convention and that that treaty expressly prohibits scheduled international air services.
In anticipation of the increased volume of permit applications from EEA carriers, the CAA has already upgraded its systems for permit processing and recruited additional staff. All scheduled permits are issued on a seasonal basis. The next summer season starts on 31 March 2019, so there is a predictable increase in workload for this. We are expecting 100 to 150 seasonal permit applications. The CAA currently issues around 3,000 ad hoc permits a year. It is preparing to be able to process at least double that if necessary.
