Cathay Pacific check-in offers travelers several flexible options to ensure a smooth start to their journey. For those using Cathay Pacific online check-in, the service opens 48 hours before departure for Marco Polo Club and Asia Miles members, while non-members can check in 24 hours prior via the official website or the Cathay Pacific mobile app. This convenient option allows passengers to select seats, add baggage, and download a digital boarding pass directly to their device. At the airport, Cathay Pacific check-in counters typically open 3 to 4 hours before the flight and close 60 minutes prior to departure, although certain airports, particularly in mainland China, may close check-in as early as 40 minutes before takeoff. For travelers departing from Hong Kong, the airline also provides an in-town check-in service through the Airport Express, available from 24 hours to 90 minutes before departure. To avoid delays, it’s strongly recommended that passengers arrive at the airport at least 2 hours in advance for international flights. Whether you're using Cathay Pacific’s app check-in, the Airport Express in-town check-in, or the traditional airport counter, having your boarding pass ready and confirming your baggage allowance in advance can significantly speed up your travel experience.
