What's happening to all the airlines of the world?
nothings happening to the airlines of the world,
but to take off and land in the UK they will need something in place to replace the European Avaition Safety Agreement, as the uk will no longer be part of it, as it is govenrned by European courts that we cannot be subject to any more.
So we need an aviation safety department, or to expand the civil aviation authority, a protocol for maintenance and safety, a few thousand trained staff to carry out such a protocol, the premises in which to do it, the laws past to make give courts the weight to enforce it, an insurance company to underwrite this, and of course separate diplomatic agreements with around 20 governments to accept our protocols.
Until this is in place, no plane can take off or land in the uk, other than on internal flights.
Or of course, we need to back down, and agree to remain part of the European safety agreement,, which will include the UK remaining subject to the European court,
if neither of these things happens in the next few months, UK airspace closes.
Airlines are now specifying that there will be no refunds in the event of UK airspace closing
Heathrow has borrowed enough money to shut down for 2 months, and continue to pay all staff, but beyond that, staff start losing their jobs, which means we won't have staffed airports even if it is resolved a year or so down the line.
Kent county council has brought in emergency protocols to close the M20 and use it as a holding area for freight entering and leaving the UK through the tunnel, in the event of the closure of UK airspace, so realistically, no likley option of passengers leaving that way either.
as no one knows whether airspace will close or not, or if or how this situation will be resolved, it would be silly to buy air tickets for after march 2019.
