Very messy with French Minister indicating they may have to stop planes flying into or overflying France

( ....many of us thought they had already , but that's another story :) )

Tit for tat as the French probably haven't thought about the UK blocking airspace to ALL flights overflying UK effectively stopping not just the French but ALL EU-US flights for EXACTLY the same reason!

An idea mentioned by Ian Duncan Smith should technical compliance be raised funnily enough by the French!

An expression involving cutting off noses springs to mind ...

No change then as they do that every year with their ATC strikes :(

Empty Threats
 

Just empty threats from France as per usual.

I mean I doubt they'd want to see an enormous drop in passenger figures and income into Paris-CDG & Nice from the UK, not forgetting that UK flights into French regional airports like Avignon, Bergerac, Béziers, Chambéry, Dinard, Grenoble, La Rochelle, Le Touquet, Limoges & Nîmes outweigh many other airlines in terms of passenger numbers, or in some cases only have UK airlines operating into them - so many regional areas will be up in arms...

Not likely, but possible: see Qatar
 

Watching a parade of Austrian registered easyJet flights arriving and departing Gatwick recently, I was wondering what was the point of this wholesale shift from the UK register to the Austrian. My guess was as a backstop arrangement to protect easyJet from post-Brexit rule changes restricting, or even stopping, flights by UK carriers into Europe. If that guess is correct, have easyJet wondered what would happen if the UK government said something along the lines of "You ban our flights into Europe and we will ban yours on a reciprocal basis"? If the easyJet move is indeed for protection against post-Brexit disruption, could it all go wrong?

Yes people are aware of the importance of internal EU routes but the UK is also extremely important to them and both the biggest LCCs have their biggest bases here. UK to the EU is an extremely large and lucrative market which if denied access to would hurt all the major airlines in Europe some more than others.

Speculate all you like, but the fact is that with six months to go there are no legislative or regulatory agreements in place for flights between the UK and the EU after we leave.

That isn't a lot of time to get 'seamless' processes in place, especially if it really is "nothing is agreed until everything is agreed"

Different set of circumstances, but then how do the likes of saudi etc stop ELAL flying over them??

Presumably if the UK doesn't have internationally recognised certification for it's aircraft I can see that being a problem not just for flights into France but into the EU as a whole and elsewhere. I don't think it has much to do with what a particular French/UK politician wants or doesn't want.​​​​​. It's a bit like Euratom and internation movement of radioisotopes/ technology after Brexit, without international agreement it becomes legally impossible. I think it's more likely agreement will be reached but all remaining UK owned airlines will change ownership to majority ownership by an EU country before April 19 and UK citizens may need to apply for a visa waiver (with a fee) to travel to the EU. Looking at the pattern of negotiations so far at each stage the UK starts by talking tough before signing up to all EU requirements at the last minute. I think we will see this again with the UK signing up to whatever the EU put on the table at the end of the day. We will no longer be rule makers but rule takers and that will be the legacy of Brexit in my view. It will be Brexit in name only.
