What currently happens is that there are agreements in place, governing what will happen in the event of accidents, whose police will intervene,in case of aggressive behaviour, or labour disputes with cabin staff etc and all these are ultimately linked to ECJ decisions. Now alternatives can be agreed and set up..eg. they exist with US and Asian carriers.. BUT THEY MUST BE SET UP. Ryanair has made multiple references to this in the past .Why would European countries stop us from flying into their country?
At present any UK carrier can insist under EU competition law to have the same landing rights as any other EU carrier in regional airports.. (yes we aare looking at you Ryanair and say EasyJet) , post March, that UK carrier loses that right.
My understanding is thaat a limited agreement has been cobbled together so that planes are not grounded on 30th. March.
