Travel to Taiwan with Mrs. 350zrx330 next month. On the return, we will fly KHH-TPE with CI first before connecting with the NW flight on the same day. CI normally check our luggages all the way to our US destination, but never put on any priority tags for us, last time we had to wait a while for luggage at DTW.

My question is can I ask for two extra priority tags on the outbound so that on the way back I can ask the CI agents to put those tags on at KHH?
