A bit off topic but related for people who fly for ski trips. Hiking poles are not allowed as carry-on when flying. I always put mine in the Sportube so it's not an issue. Collapsible poles in checked baggage is okay.
Does depend on the airport. Pretty sure I had my collapsible ski poles when I flew carry-on only from RDU to Boston last March. Have heard of poles being confiscated at Newark.
