Given a travel related situation, and given a specific question about the situation, summarize the question into a title

Ex Input:
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?

Ex Input:
I have recently traveled to Lisbon and almost each day while being there I have received the same message thorough a cell-broadcast channel on my mobile phone:


  21 Lisboa


I have asked my host, but she did not know what this message meant. I am thinking it might be related some weather warnings, but the worst thing I have endured was a light rain.

Question: What does "21 Lisboa" cell broadcast message mean?

I'm planning to take an elderly couple from Shanghai to Nantong. I'm looking for a more comfortable alternative than the intercity buses.  

Are there any companies who offer intercity taxi or minivan for a decent price?
