I am planning a trip and contacted Asia Miles to determine the number of miles for seat upgrade from Economy to Premium Economy.

Vancouver - Hong Kong - Singapore - Hong Kong (connection en route home) - Vancouver

They indicated to create my revenue booking without issuing revenue ticket via travel agent. I don't get what the means?

Last time I booked (paid) a flight on Cathay Pacific and then upgraded with Asia miles to premium economy on the the CX website and it worked fine, assuming there is availability.

Thanks.
