It depends on how you bought the ticket.

The situation that will be listed is: if the air ticket is booked through Ctrip and paid online, then Ctrip will provide the information of where to fly to in the bill details of the CMB credit card (I also have the CMB Classic Platinum Card, The bill details list is shown in the picture below, you can click on the picture to view the original size). As far as my actual experience in purchasing air tickets online, in addition to Ctrip, online payment for air tickets on Mango.com, Elong.com, etc. will be included in the bill details.

The situation that will not be listed is: if you swipe your card to pay for the ticket at a travel agency or airline ticketing point in any physical store, it will not be listed because UnionPay only synchronizes the name of the travel agency or airline ticketing point after the card transaction. There is no information on where you are flying from.
