Good news: KA interlines with CX! So you can check your bags to your final destination and not have to reclaim them in HKG. That makes your connection much nicer. You may need to produce your CX ticket number at checkin for KA so be sure to have a printout showing this!!! Very important and the most annoying feature of e-tickets -- you need to print them yourself and the printout is often essential.

For everyone's info, CX interlines as follows
CX-160 CATHAY PACIFIC AIRWAYS (as of Aug 2012)
