I am traveling internationally and want to bring my carbon fiber German bass bow. The case exceeds the carry-on baggage limit length. On the other hand, Air Canada Musical Instrument Policies 2022 states: "Exception: String instruments (e.g. guitars, violins and violas) can be carried on board - even if their dimensions slightly exceed Air Canada’s carry-on size requirements - as long as they fit in the overhead bin and there is space available in the cabin at time of boarding" The bow case won't fit my check-in luggage. Should I risk trying to bring it as a carry-on? Advice needed!
