• Self-service kiosks: If you arrive at the airport, find the kiosks around the counter, scan your passport or ID, and follow the prompts. You'll then get a physical boarding pass.
• Airport counter: If you need to check in luggage or more services like a wheelchair, traveling with pets, or have an infant, better choose this way for more convenience.

The short answer: Yes! If you booked through Trip.com, look for the "Smart Check-in" feature in your Trip App.

It’s a set-it-and-forget-it tool that attempts to check you in automatically as soon as the window opens. If for some reason it’s not supported for your specific route, don't worry—just use your e-ticket number on the airline’s official site.

• Domestic Flights (within China): Online check-in usually opens at 2:00 PM the day before your flight. It closes about 45 to 60 minutes before departure.
• International Flights: Typically, you can check in 24 to 48 hours before takeoff.

My Advice: Set a reminder for the 24-hour mark. China Southern’s popular routes fill up fast, and early birds definitely get the best legroom!

Recommended Airport Arrival Time for China Southern Flights

• International: Give yourself 3 hours.

China Southern Baggage Allowance by Cabin Class

Traveling from U.S. to China is a long haul journey. When packing your bags, remember to be careful about carrying these items:

• About power bank: Treat your American power bank as a liability in China. Pack a high-quality Wall Charger instead. Once you land, buying a locally certified 3C power bank is a cheap and stress-free way to ensure you never get stopped at a security checkpoint.
• About plug type: China uses Type A (two flat pins, like the US), Type C, and Type I (three-pronged angled).
• About liquid: All liquids, gels, and aerosols must be in containers of 100ml (3.4 oz) or less.

Tips for Choosing Better Seats on China Southern

If you want a quiet, grounded flight experience, keep these tips in mind:

• Aircraft Matters: Look for the Airbus A350 or Boeing 787. These planes are quieter and have better cabin pressure, which helps with jet lag.
• The "Secret" Rows: Check seat maps on the app early. Sometimes the "Economy Comfort" seats (with more legroom) open up for a small fee during check-in.
