Stormy skies trigger wave of flight delays at HKIA; Hong Kong Airlines HX628 departs 49 minutes late

Persistent thunderstorms associated with the strong monsoon played havoc with Hong Kong International Airport’s departure bank on 4 July. Flight-tracking data from Cirium FlightStats show dozens of outbound services left behind schedule between 08:00 and 12:00. Among the largest delays was Hong Kong Airlines flight HX628 to Seoul, which pushed back at 09:34—49 minutes after its planned 08:45 slot—arriving 37 minutes late at Incheon. Air-traffic-control sources said aircraft departing runway 07R faced intermittent wind-shear alerts and low-level microbursts, forcing controllers to increase separation and occasionally hold departures on taxiways. While most long-haul departures managed to leave within an hour of schedule, short-haul sectors to Guangzhou, Taipei and Xiamen saw turnaround-based knock-on effects throughout the afternoon. FlightStats’ live dashboard recorded an average departure delay of 24 minutes across 152 flights by mid-afternoon, placing HKIA among Asia-Pacific’s five most disrupted hubs for the day. Travellers reported security-checkpoint queues spilling into the Terminal 1 transfer hall as passengers whose flights slipped into new time belts triggered re-screening peaks.

For travellers whose onward journeys require last-minute visa adjustments—especially when delays threaten tight layovers—services like VisaHQ can be invaluable. The company’s Hong Kong portal provides rapid e-visa processing, document checks and expert guidance, helping passengers avoid additional disruption when weather throws itineraries off course.

For corporates, the micro-disruptions translate into cost: same-day itineraries risk missed meetings, and per-diem claims rise when staff exceed maximum duty hours. Mobility managers are therefore encouraged to deploy real-time flight-tracking tools and to brief employees on the airport’s complimentary lounge vouchers issued after two-hour delays. The Airport Authority says both runways remain open and that it will work with airlines to recover schedules once convective clouds clear late on Saturday night.
