Track HK Express (UO) flights in real time: enter a flight number (e.g. UO1234) or route to see scheduled/estimated times, check-in counters and gates.
All HK Express flight numbers start with "UO". Check status via the Trip.com flight status page below, the airline's app, or the airport website — once the night before and again on departure morning.
Tip: the inbound aircraft's status predicts delays earlier than your own segment's — watch it on the status page. In thunderstorm season, evening departures are far more delay-prone than mornings; pick early flights for critical trips.
