What is also agrivating is that in this insecure situation, it is impossible to purchase travel insurance, to cover Brexit related missed connections. For example my return is by British Air, one stop - Edinburgh-London-Palma. If for some Brexit reason, the flight into Edinburgh is dalayed, this will snowball. I can get a flight from London to Palma, but the train from Glasgow to London not only costs more then the flight from Scotland to Palma, but the connection time from King´s Cross to London City Airport allows me 2 hours. Again British rail is horrible, usually late, the cross london connection involves the underground and another train, plus check in time and security - this would be a close call, and probably involve an expensive hotel stay in London, because without insurance, and no airline responsibility, the airline would not have to provide meals and hotel. If I felt there would be a problem, It would be better to stay an extra night in Glasgow, but there is no refund on a prepaid ticket.
The world is changing. Back in the 60s, I lived in the L.A. area, and taught classes in S.F. the flight cost 25$, no security, all I had to do is show up at the airport 35 minutes ahead of my flight, walk on, walk off.
This is an anti Brit off topic.
Not only does the U.K. not use the Euro, but while their electricity is compatible, their plugs are not.
Years ago, at St Andrews, I ran an indictrination course for American 3rd year abroad students. I explained that while such things as hair driery had a voltage switch, the difference was such that an American hairdrier would not survive the first term. Next day a girl complained that when she bought a U.K. hair drier, it did not come with a plug (how cheap she said). I said no that was smart because until she got to her dorm or residence, she would have to decide what plug to purchase since U.K. sockets are not standard, usual then was round pin but no the same as the E.U. or square pin, three prong.
Last Spring, I was a guide-coordinator for a group from Bengal, where India still uses U.K. plugs, but this was Spain. Fortunately I had a set o adaptors for their phones lap tops etc. In two weeks I will be in Scotland, and have already packed a set of adapters for both U.K. type sockets, important because my lectures require my European lap top.
There are two down sizes to national pride/chauvinism. The U.K. drives on the wrong side of the road, and is aware of this when here, but when they rent bikes, they forget that pedestrian and biking conventions are the same as in the U.S. so I keep running into
Brits on bikes in my bike lane, and getting a look like it is my fault. Fortunately the U.K. got smart around 1970 and went decimal for currency, weights and measures. On the other hand the U.S. which got smart with its currency after the American revolution, it is probably the only country in the world where Britesh weights and measres are still used. Like America we have dealership garages for cars, but outside the city, most work on cars is done in one off garages, which can´t handle american vehicles because they can´t afford two sets of tools. In my farm village, the most common vehicles are CAT and John Deere tractors, but if there are engine problems, they have to be towed to a distant dealership. Bad for U.S. business not just in vehicles, but other things as well - converter and two sets of measuring divices for cooking, our beds are metric so fitted sheets don´t fit.
