What's the point of worrying about reschedules or cancellations? Take that to an extreme and nobody would ever go anywhere by plane, ship or train.
This is THE most ridiculous answer ever. If someone like myself is tied to 3 days (72 hrs from start to finish) and are restricted to the number of breaks they can take - then to lose more than a couple of hours severely dents your valuable spare time. Those holiday hours are to be spent on a beach, in the sea, in the bar (!) and not hanging around airports wondering if you will get there/back; and no amount of compensation covers the lost time - it won't come back.
Take out personal travel insurance. It's inadvisable to travel without it and rely on a EHIC, but if you're willing to you can wait until the day before, and if EHIC still works, save the 20 quid or so.
I do, but travel insurance doesn't cover everything - may not even cover a fall if someone's got alcohol in them - the EHIC does. Also for many who have pre-existing conditions health insurance is impossible or extremely expensive (ie after a heart by-pass or someone with mild dementia) so they would be covered for accidents and emergencies. Is it the Big Idea for Brexit to prevent the elderly or ill from travelling?
Who goes on holiday to use their phone more than a bare minimum? If it is important though, have a phone with one of the providers who've said they've no plans to change anything, or with Three, who've said they won't be.
Having no pland doesn't mean they won't change - I give you one T. May! However, having a phone handy is useful if you have to connect in an emergency and not have to worry about the cost. When my mum fell seriously ill last year, I was so glad I could keep in touch with the carers and hospital, book an emergency flight home and no have to worry about a large data bill on return. Must have spent hours on the phone and video during that awful evening.
Which rights? ATOL and the CAA will still exist
The rights the EU have given delayed or cancelled passengers. To be fair - our government has indicated they will strengthen thise after Brexit, so that's a plus if they do. However, what they say and do....
We've done this numerous times already too, and you still don't seem to understand what tourist visas and visa waiver schemes are. Massively unlikely to be any material change, at worst the most belligerent of outcomes would be paying in the region of a tenner.
Many innocent people will fall foul of the Schengen Visa - have you seen what it consists of? Name your first night's stay for example. Huh...day trips?? How much money have you got? And most worryingly, you have to indicate medical conditions. Again, hopefully it won't come to that..but what are the odds?
If you're booking flights that seems a bit irrelevant, as you won't be taking your car.
Er, car hire anyone?? Will we need an international licence on top? And, of course, many have flight holidays + drive and ferry ones too at seperate times.
Seriously, don't. What's the point? Your predictions may (cough) or may not come true. Why use theoretical scenarios which haven't happened to deny yourself your holiday? If you're right you might never be able to leave the country again, so it's worth taking a gamble that you might just be able to have one last holiday during the "transition period", surely?
If I had a severe medical condition - maybe a stroke (or even family history of conditions which are hereditary and haven't yet struck???) and couldn't afford the huge insurance bill (EG USA today) then there's every chance I wouldn't be "allowed" to leave the country again. That what you want, guv?? Nice one bud, hope you never fall ill and want a break. Cheers.
