Again, as per the other thread: it is beyond belief that people genuinely seem to think that there’s the slightest chance of flights between the EU and the U.K. suddenly grinding to a halt post-(hopefully no deal) Brexit. It simply will not happen.
Both sides stand to lose far too much. The U.K. is not suddenly going to become a pariah state cut off from the rest of the world, with no transport links in or out. Honestly remoaners: must try harder.
