In the terms and conditions for an airline ticket, I have encountered this:
Cancellations rules apply per fare component. When combining fares charge the sum of the cancellation penalties of all cancelled fare components.
The ticket involves two legs, one directly on the airline, and the next leg is on a code share airline.
I'm trying to find out how much it would cost to cancel this ticket, but I'm not sure if there is one or two "fare components" in the ticket.
Specifically, this is a one-way ticket from Lisbon, Portugal to Charlotte, NC on Air Portugal (book.flytap.com).
