I have an itinerary that goes YYZ-JFK-LAX-MEL-SYD-AKL, my travel plans have changed since then and I want to cancel/redeposit.
Only thing is the YYZ-JFK segment has been downgraded to Economy from Business since I've booked it. Is that a reasonable ground to ask for a free redeposit even though it's a insignificant flight when the whole itinerary is considered?
