While the typhoon dominated headlines, airlines also had to contend with an unexpected air-traffic bottleneck over the Pearl River Delta on 10 July. At 07:55 UTC (15:55 HKT) the Hong Kong Civil Aviation Department (CAD) published a Notice to Airmen (NOTAM) imposing flow-control measures on aircraft “overflying Hong Kong via TAMOT destination ZGGG [Guangzhou]”.

For travelers and mobility coordinators scrambling to adjust itineraries during such disruptions, VisaHQ can take at least one headache off the table: travel documentation. Through its Hong Kong platform, the service expedites visas and entry permits for crew and business passengers alike, freeing up time to manage flight changes instead of navigating consulate queues.
The memo cited “sector capacity” constraints and ordered carriers to obtain slot times or reroute. The TAMOT waypoint is one of the busiest hand-off points between the Hong Kong Flight Information Region and the Guangzhou FIR, funnelling traffic from Southeast Asia toward mainland hubs. According to flight-tracking firm VariFlight, average en-route delays for Hong Kong–Guangzhou overflights increased from 6 minutes on 9 July to 34 minutes after the NOTAM took effect. Cargo carriers such as FedEx and SF Airlines opted to divert via the BETTY and IDOSI fixes to maintain connection times at Guangzhou Baiyun’s overnight freight banks. Industry sources say the restriction is linked to Guangzhou ATC staffing shortages caused by precautionary typhoon redeployments and summer peak demand. The Hong Kong Air Cargo Carrier Association warned members to “expect rolling ground-delay programmes” through the weekend and urged proactive flight-plan filing at least six hours prior to estimated off-block time. For global-mobility teams, the immediate impact is longer block times on intra-Asia itineraries—particularly for corporate charters and private jets, which often file last-minute flight plans. Travel managers should budget extra connection buffers for staff shuttling between Southeast Asia, Hong Kong and the Greater Bay Area, and monitor CAD notices via the AIS web portal.
