I have personal knowledge of China Eastern Cancellation Policy because I recently had to cancel a flight with them. The first step in the simple process was to validate the parameters of my ticket with their customer service personnel. Despite the fact that my ticket was non-refundable, I was made fully aware that I could get a partial refund after cancellation fees were subtracted. I valued the openness and thorough instructions on how to use their website to submit my cancellation request.
