I was in queue over 1 hr at Taoyuan airport cx drop-off luggage counter, and I had to run to the gate to the flight after x ray check & custom. My flight was on 2 Jun and the flight no CX451. I think the airline should open more counters if more flights onboarding, (it was 4 counters opened for 4 flights). It was hopeless!
