Q: As seen in the Politics SE:


  Right now, you can jump on a ferry in France, head over to Cork, drive up to Belfast and catch the ferry to Liverpool, without ever showing your passport to anyone. It seems inconceivable that this arrangement could be maintained if and when the UK leaves the EU. 


Best I'm aware you'd need to show your passport before boarding in France, in much the same way that you do when taking the Eurostar to London. Because Ireland, like the UK, isn't part of the Schengen zone.

Which is it?

Bonus question: would you also need to show your passport to go from Belfast to Liverpool, or is that second assertion factual?


A: Do you need a passport to take the ferry from France to Ireland?

Q: Often I book a return ticket with a transit, and then ditch only the route from the transit to the destination of the return flight. In other words, I get off at the transit place only in the return flight.

However, I have an experience of being handed a direct ticket in case of an emergency, even though the original ticket included a transit. For example, my original ticket was from Seoul to Tokyo with Shanghai as a transit, but since the flight operated by China Eastern was delayed for some reasons, I was instructed to get on a flight operated by Korean Air to directly go to Tokyo.

At that time, I didn't plan to get off at Shanghai, so it was not a problem. However, now I wonder if it is possible to decline the alternative ticket handed at the check-in counter. I usually book an onward ticket as well as my room in advance before stating that I like to get off at the transit airport; even the airline staff told me that I must state it at the check-in counter since they don't accept it via a phone call or email in advance.

So can I decline the alternative ticket? If not, is it the airline or I that should book another ticket that can get me off at the transit airport?


A: Can I decline an alternative ticket handed at an airline's check-in counter in case of an emergency?

Q: Next spring (second week of May), I'm looking to explore upstate New York before my sister's graduation from Syracuse - I live in California, and have never been to New York outside the city, so I've been exploring various travel options. Everything I've seen has made Buffalo much more attractive of an option, price-wise, to the point that I think it might well be worth the extra ~hour out of the way (from what I can tell from Google Maps) compared to the Rochester airport, or the Syracuse airport (obviously much more convenient; also crazy expensive from the west coast, plus I'd rather get the excuse to explore more anyway.)

I can handle the extra drive time, but as I've never been to that area, I figured I would ask to make sure, weather-wise, whether that plan would be foolish. My mom, who has visited my sister there before, says when she was there in mid-April, there was still snow everywhere. So I suppose my two questions would be: 


If I were thinking of driving from Buffalo to Letchworth National Park, then to Syracuse by way of passing through Watkins Glen, then back to Buffalo (obviously not in a day - I'd have over a week for this trip), how likely is it that I would encounter weather hazards (i.e. snow) in early May? 
If the answer to #1 isn't "highly unlikely", and I were in a budget rental car, how well maintained would those roads be / how well equipped would a budget rental be to handle said hazards?
