Thirteen hours. That is a long time to be stuck in a metal tube, even if that tube is a state-of-the-art Airbus A350-1000 or a Boeing 777-300ER. When you are looking at flights for Cathay Pacific Hong Kong to LAX, you aren't just buying a seat. You are basically committing to a half-day of your life in a pressurized cabin over the Pacific Ocean.
Most people just look at the price and hit "book." That is a mistake.
Flying between Chek Lap Kok (HKG) and Los Angeles International (LAX) is one of the premier transpacific routes in the world, but the experience varies wildly depending on which flight number you grab and what time you depart. Honestly, the 1 a.m. departure feels completely different from the afternoon flight. Your body clock will either thank you or absolutely hate you by the time you hit Tom Bradley International Terminal.
The Aircraft Coin Toss: A350 vs. 777
Cathay Pacific currently rotates two main heavy-lifters on this route. You’ve got the Boeing 777-300ER, the old reliable workhorse, and the Airbus A350-1000, which is the sleek, quiet newcomer.
If you're in Economy, the A350 is usually the winner. Why? Better humidity. The A350 is built with carbon-fiber reinforced plastic, so they can keep the air a bit more moist without worrying about the plane rusting from the inside out. You won't wake up feeling like a piece of human beef jerky. Plus, the windows are bigger.
But wait. If you are a fan of First Class, you have to hunt for the 777. The A350 doesn't have a First Class cabin. It’s Business, Premium Economy, and Economy. The 777-300ER is where those legendary Cathay First suites live—the ones with the wide seats that feel more like a couch than an airplane chair.
Don't assume every flight is the same. Check the seat map.

I've seen people get really frustrated because they expected the new "Aria" Business Class suites and ended up on an older 777 layout. The Aria suite is Cathay's newest pride and joy, featuring a sliding door for privacy. It is slowly being rolled out across the 777-300ER fleet, but it's a bit of a gamble right now. If you get it, you're golden. If not, the older Cirrus seats are still some of the best in the industry, even if they show a little wear around the edges.
Timing Your Cathay Pacific Hong Kong to LAX Flight
Timing is everything.
Cathay usually runs multiple frequencies daily. The "midnight express" (flights leaving around 12:00 AM or 1:00 AM) is the gold standard for business travelers. You eat, you knock out for eight hours, and you land in LA in the evening. You go to your hotel, sleep again, and you’re basically adjusted.
Then there are the afternoon departures.
These are trickier. You leave HKG at 4:00 PM and land in LA around 1:00 PM the same day. It feels like time travel, but the jet lag is brutal. You’ve spent the whole flight awake because it's daytime, and then you have to power through a whole afternoon in California before you can sleep. It’s rough.
The Lounge Situation at HKG
If you have Oneworld status or you’re flying upfront, the Hong Kong lounges are the best part of the trip. Period.

- The Pier (First Class): This is the one people write home about. It doesn't feel like an airport. It feels like a high-end apartment in Mid-Levels. There are daybeds. There are foot massages. The dining room serves actual restaurant-quality Dan Dan noodles.
- The Wing: Famous for the "Cabanas." These are private bathrooms with full-sized tubs. If you want to soak in hot water while looking at the tarmac before a 13-hour flight, this is your spot.
- The Deck: Smaller, but has a great terrace. Good if you want to people-watch or smell the jet fuel.
Most people don't realize you can lounge-hop. If you have the time, start at The Wing and migrate toward your gate, stopping at The Pier. Just don't get so relaxed you miss the boarding call. It's a long walk to some of those gates.
What's It Like in the Back? (Economy and Premium)
Let's be real. Most of us aren't in a suite.
Cathay’s Economy is decent, but it's tight. The 777s moved to a 10-abreast seating (3-4-3) a few years ago. It’s snug. The A350 is 3-3-3, which feels a bit more spacious.
The food is usually a step above US carriers. You’ll get real Hong Kong flavors—think ginger chicken or braised pork. And yes, they usually have Haagen-Dazs ice cream for dessert. It's the small wins that matter when you're over the North Pacific.
Premium Economy is the sweet spot for this route.
You get a dedicated cabin, more recline, and—crucially—a leg rest. On a 13-hour haul, being able to elevate your feet is the difference between sleeping and just "resting your eyes" while staring at the back of a headrest. It’s often $500–$800 more than Economy, which is a lot, but for 7,200 miles? Sorta worth it.

Dealing with the "Pacific Gap"
When you fly from Hong Kong to LAX, you are crossing the International Date Line.
You will likely lose a day or gain a day depending on which way you look at it. This messes with your tech. Your iPhone might get confused. Your calendar invites will definitely get confused.
The WiFi on Cathay's A350 and 777 is generally reliable. It's not "stream a 4K movie" fast, but it’s "send emails and annoy your friends on WhatsApp" fast. They offer a flight-long pass which is usually around $20. If you're working, it's a no-brainer. If you're trying to disconnect, just know the entertainment system (StudioCX) has one of the best selections of Asian cinema and HBO box sets in the sky.
Navigating LAX Upon Arrival
Landing at LAX is the final boss.
You will arrive at the Tom Bradley International Terminal (TBIT). If you have Global Entry, you’ll be through in five minutes. If you don't? Prepare for a wait. The lines can be legendary, especially if three other A380s from Emirates or Lufthansa just landed at the same time.
Pro tip: Use the Mobile Passport Control (MPC) app. It's free. Often, the line is almost as short as Global Entry.
Once you clear customs, you're dumped into the arrivals hall. If you need a ride, remember that LAX doesn't allow Ubers or Lyfts to pick up at the curb anymore. You have to take a green shuttle bus to the "LAX-it" lot. It’s a bit of a hassle after a long flight, so follow the green signs.
Actionable Steps for Your Next Trip
- Check the Aircraft: Use a site like FlightRadar24 or SeatGuru to see if your specific flight number is an A350 or a 777. Prioritize the A350 for better air quality if you're in Economy.
- Book the Midnight Flight: If you can, take the flight that leaves HKG after 11:00 PM. It aligns best with your circadian rhythm for a California arrival.
- The Noodle Strategy: If you have lounge access, eat your main meal at The Pier or The Wing before you board. The food is better than what's on the plane, and it lets you maximize sleep time once you're in the air.
- Download the App: Use the Cathay Pacific app to check in 48 hours early. This is when the "extra legroom" seats (exit rows) often become available for a fee if they haven't been snapped up by elites.
- Hydrate Early: Start drinking water three hours before departure. The Hong Kong airport has plenty of water stations; fill up your bottle after security. Relying on the little 4oz cups the flight attendants bring around is a losing game.
This route is a marathon, not a sprint. Cathay Pacific remains one of the most consistent ways to do it, but success depends on the details you choose before you even leave for the airport.
