Yes, the Hong Kong Airport Express check-in service is up and running as of 2025. It’s a reliable and fantastic option if you’re flying with a participating airline.

Here is the essential information for your travel plans:

• Who Can Use It? The service is available for passengers of four major airlines. Cathay Pacific was the first to return, followed by Hong Kong Airlines, Qantas Airways, and most recently, Singapore Airlines back in February 2025.
• Which Stations Are Open? You can use the service at two main locations. Hong Kong Station has full services for all four airlines during their specific hours. Kowloon Station is also open, but the hours are a bit shorter and not all airlines are there yet. The check-in desks at Tsing Yi Station are still closed.
• What’s Next? The MTR Corporation is committed to this service. They plan to bring more airline partners back on board through 2026. For now, just plan your trip based on the airlines that are currently confirmed.

This comeback is great news. It puts the Airport Express station facilities back on the map as essential travel hubs for the city.

Hong Kong In-Town Check-In: Which Airlines and When?

You’ll need to know exactly which airlines are part of the service and their hours at each station. The Hong Kong in-town check-in airlines timetable can change, so here are the confirmed details for 2025.

The Official List of Airlines

Here’s a simple table with all the info. Just remember, the service is only for flights operated by that airline, not for codeshare flights.

Quick Note: These are the hours for the check-in counters. You still need to check in at least 90 minutes before your flight leaves. It’s always smart to double-check with your airline’s website before you head out.

A Closer Look: Cathay Pacific (CX) Airport Express Check-In

Since Cathay Pacific was the first to bring the service back, cathay pacific in-town check-in is the most popular option. The long service hours at Hong Kong Station make the cx Airport Express check-in a fantastic perk for anyone who flies with them.

• Great Availability: It works for almost all Cathay Pacific flights.
• The Big Exception: Because of U.S. security rules, you cannot use In-Town Check-In if you are flying to any city in the United States. You must check in at the airport for those flights.
• Station Choice: The long hours at Hong Kong Station and the afternoon service at Kowloon Station give you great flexibility.

The Golden Rules for Check-In Time

Timing is critical. Follow these official Airport Express check in time rules to make sure your bags get on the plane.

The rules are simple and they apply to all the airlines.

• Check-In Early: You can check in as early as 24 hours before your flight. This is amazing if you have a late flight but need to get out of your hotel or apartment in the morning.
• The Final Cutoff: You must finish checking in (and drop your bags) at least 90 minutes before your flight departs. This is a strict deadline. It gives the staff enough time to get your bags securely to the airport and onto the plane.
• Counter Closing: The service for your specific flight will shut down exactly 90 minutes before departure. Don’t be late. If your flight is at 5:00 PM, you have to be done by 3:30 PM.

The Fine Print: Rules on Luggage, Tickets, and More

Here are a few more important rules to avoid any surprises.

Hong Kong Airport Express Check-In Luggage Rules

The baggage rules are for standard travel, so be aware of the limits.

• Size and Weight: Your checked bags can’t be bigger than 145cm (L) x 100cm (W) x 85cm (H) or weigh more than 32kg each. You also have to follow your airline’s own baggage allowance. If your bags are over the limit, you’ll pay the excess fees at the counter.
• Carry-On Items: Remember, standard security rules apply. Things like power banks, spare batteries, and lighters must go in your carry-on bag, not your checked luggage.
• Special Bags: The service can’t handle oversized items. If you have a bicycle, skis, a giant cello, or a pet, you’ll need to check those items at the special counters at HKIA.

Who Can Use the Service?

Your eligibility depends on your ticket and travel documents.

• Ticket to Enter: You need an Airport Express ticket (QR codes from Trip.com work perfectly) or an Octopus card to get into the check-in hall.
• Electronic Documents Help: The service, especially the fast kiosks, works best if you have an electronic travel document like an e-passport. The scannable chip speeds everything up.
• Who Should Go to the Airport? The service is not set up for passengers who need special assistance. If you are an unaccompanied minor, need wheelchair assistance, are traveling with a pet, or are on a standby ticket, you should go straight to the airport to check in.

The Smartest Way to Start Your Trip

The return of the Airport Express In-Town Check-In service is fantastic news and shows why Hong Kong is so great at making travel easy. If you fly with Cathay Pacific, Hong Kong Airlines, Qantas, or Singapore Airlines, it offers a huge advantage. You save precious time, get rid of stress, and have the freedom to enjoy your last day in the city. It turns a hectic travel day into a relaxed one.

So, before you go, do one last thing: check the official MTR and your airline’s websites for the latest updates. This quick check will guarantee your trip starts off perfectly.
