Basic connectivity
The EU has agreed measures to allow "basic connectivity" for a year, to prevent planes being grounded the day after a no-deal Brexit.
UK Aviation Minister Baroness Sugg has confirmed that this will be reciprocated.
This doesn't provide the exact same access as before, though.
It allows for "point-to-point" trips - from the UK to another EU country and vice versa.
But it doesn't cover onward flights to other European countries - or flights by EU carriers between two UK cities.
I see the above as a key point for 99.9% of those of us flying in from N America. There really be no change, from the traveler's perspective, but business and bureaucrats will continue to be busy setting up the 'new rules'. It appears they have already set up interim policies to keep things moving.
I have no travel plans taking me to/through England this year, but if I had reason to travel, I would not let Brexit deter me.
