Hong Kong flag carrier Cathay Pacific Airways will shorten its boarding and gate closure times by five minutes to help ensure on-time departures. The airline said on Thursday that, from June 1, boarding gates at Hong Kong International Airport will close 15 minutes before departure. The boarding time will also move forward five minutes. The company said late-arriving or no-show passengers were a key cause of delays, as safety regulations required removing their checked baggage from the aircraft.
