Not really a hidden city question
Reading with interest the latest hidden city thread prompted me to recall an incident about ten years ago (for my first ft post).
Returning with Finnair from Shanghai to Copenhagen via Helsinki, the flight was delayed 2-3 hours from Shanghai, and thus was late arriving in Helsinki. I had a (separate, not Finnair) ticket from Copenhagen to Stockholm, my final destination for the day, which I was obviously going to miss.
So in Helsinki I saw that there was a Finnair flight to Stockholm almost immediately, and asked to be put on it. Rather to my surprise, the Finnair transfer agent agreed, with the result that I arrived in Stockholm earlier than if everything was on time. And I could just throw away my Copenhagen - Stockholm ticket.
No real question here, just an anecdote, wonder if it is particularly unusual ?
