For the Toronto Pearson International Airport departure, leave central Toronto around 21:30–21:45 on October 5 to reach Terminal 3 by approximately 22:00, allowing extra time for traffic and airport drop-off. The UP Express does not run directly to the terminal, so a taxi or rideshare is simplest with luggage; driving and parking are also possible in the Terminal 3 garage. Check in for Cathay Pacific CX829 and confirm that both checked bags are tagged through to Phnom Penh via Hong Kong. The overnight flight departs at 00:35 on October 6, so keep your passport, boarding passes, and any Hong Kong transit information easily accessible.
After security, spend roughly 90 minutes at the Plaza Premium Lounge in Terminal 3. It is a useful pause before the long sector: have a light meal, refill your water bottle after security, and make use of the quieter seating rather than lingering in the busy gate area. Lounge access and hours can change, so verify availability through the lounge program or Cathay’s current airport information; paid entry is often around CAD 50–80 if access is not included. Keep an eye on the departure screens, since gates at Toronto Pearson can require a fairly long walk.
Board Cathay Pacific CX829 well before the 00:35 departure. The scheduled Toronto–Hong Kong flight is approximately 15 hours 35 minutes, crossing several time zones, so settle in for an overnight service and try to sleep early according to Hong Kong time. Business class provides a lie-flat seat and a quieter start to the journey; stay hydrated, limit alcohol, and keep a change of clothes and basic toiletries in your cabin bag. On arrival at Hong Kong International Airport the following morning, follow the marked transfer signs rather than immigration and baggage claim, since the itinerary continues onward to Phnom Penh on CX607.
After landing at Phnom Penh Techo International Airport at 10:25, allow roughly 60–90 minutes for immigration, baggage collection, and the drive into town. A pre-booked hotel car is the easiest first-day option; otherwise, use the airport’s official taxi service or a reputable ride-hailing app. The new airport is in Kandal Province, so central Phnom Penh is usually 45–75 minutes away, depending on traffic. Drop your bags at the hotel and take a proper rest before heading out—after the long overnight journey, the city is best approached gently.
Begin at the Royal Palace, where the ornate yellow-and-white buildings, manicured gardens, and silver-tiled Silver Pagoda make an easy introduction to Cambodia. Check the current visitor hours at the entrance, as the complex can close for royal ceremonies; modest clothing covering shoulders and knees is required, and admission is generally around US$10. From there, walk a few minutes to the National Museum of Cambodia, a beautiful terracotta-colored building surrounding a quiet courtyard. Give yourself about an hour for its exceptional Khmer sculpture collection, especially the Angkor-era pieces; admission is typically around US$10, with afternoon closing often around 5:00 p.m.
Take a short tuk-tuk or taxi ride to Malis Cambodian Restaurant in BKK1 for an early dinner, allowing about 1½ hours and approximately US$15–30 per person. This is a comfortable first-night choice for traditional dishes such as fish amok, lok lak, and fragrant soups, served in a polished garden setting; reservations are sensible if you arrive after 6:30 p.m. Afterwards, return toward Sisowath Quay for a relaxed 45-minute walk beside the Tonlé Sap and Mekong. The promenade is liveliest after sunset, with locals exercising, families out strolling, and small riverfront vendors; keep valuables secure and use a tuk-tuk back to the hotel rather than walking long distances late at night.
