Good post (aviation wise)
I don't think the Independent article is meant to be taken that seriously...?? Not least because it's not all going to kick off exactly on leaving day. If no deal is reached, political change in the UK will be in play before the end of this year for a start off. And the effects on aviation will be far more advanced and insidious. If no deal is reached by Christmas, only a moron (or a very rich person) will be booking flights into the EU (or perhaps anywhere) in April onwards, so there will be far fewer flights to cancel in the first place.
