Based on the latest information for February 2025, if your flight arrives at Xi'an Xianyang International Airport at midnight (00:00), here’s a quick breakdown of your transportation options to the city center:

1. Airport Shuttle Night Buses:

• Shuttle Line 1 (Night Line)

  • Operating Hours: 22:20 – 01:00 the next day
  • Frequency: Every 20-30 minutes, or as soon as the bus is full
  • Route: Airport → West City Bus Station → Xishao Men → Bell Tower Hotel → South Shao Men Xi’an Hotel → Shaanxi Sports Stadium Metro Station
  • Duration: About 90 minutes
  • Note: If your flight lands at 00:00, and you get your luggage and exit within 30 minutes, you should be able to catch the last bus at 01:00.

• Shuttle Line 5 (Night Line)

  • Operating Hours: 01:15 until the last bus
  • Frequency: Every 30-40 minutes
  • Route: Airport → City Sports Park → City Library → Long Shou Village → Bell Tower → South Shao Men Xi’an Hotel → Xishao Men Airport Business Hotel
  • Note: If you miss the 01:00 bus, you can catch the first bus of this line at 01:15.

2. Alternatives if You Miss the Shuttle:

If you miss the night bus due to delays or other reasons, here are your options:

• Taxi or Ride-hailing (like DiDi):
  Available 24/7. It’ll take around 50-70 minutes to reach the city center, costing about 100-150 RMB (depending on traffic and your destination).

  Tip: Be aware that there may be light snowfall around the airport recently, so keep an eye on road conditions and allow some extra time.

• Pre-booked Private Transfers:
  Some platforms offer pre-booked rides, ideal for groups or if you’re carrying a lot of luggage.

• Overnight Stay Near the Airport:
  If you have plans early the next morning, consider booking a hotel near the airport (some even offer free shuttle services).

3. Other Tips:

• Ticket and Pick-Up Locations:
  You can buy tickets at the T2 Terminal (1st Floor) or T3 Terminal (GTC, Ground Floor). The shuttle buses depart from the exit of T2/T3 terminals.

• Real-time Info:
  Check the latest schedules and updates via the “Bus Passenger Service” WeChat mini-program or call 029-88798787.

To summarize, even if your flight lands at 00:00, you'll still have a chance to catch the last bus on Shuttle Line 1 or the first bus on Shuttle Line 5. For exact times or any schedule changes, be sure to check official local platforms like Xi’an Ben Di Bao. Let me know if you need anything else!
