Line 4 only makes sense if your hotel is on its route
Airport Shuttle Bus Line 4 from CTU serves more peripheral districts, so only use it if your hotel or Airbnb is near a confirmed stop along the line, not just “in Chengdu.” It runs from Chengdu Shuangliu International Airport’s terminals (T1/T2) into suburban areas that aren’t covered by the main Line 1 city route.
The ride itself is fine if you know exactly where you’re getting off, matching what Chinese reviewers say about these lesser‑used lines being “fine if you know exactly where they go.” Fares on comparable CTU shuttle lines sit in the ¥10–¥20 range, so expect something similar for Line 4, which still undercuts most taxi or Didi rides from T1 or T2 by a big margin.
Line 4 has lower demand than Line 1, and local forums report that its timetable gets adjusted more frequently, so online schedules can go stale within a few months. Frequencies drop at night, and people on Mafengwo mention waiting significantly longer after 21:00 compared with grabbing a Didi straight from the arrivals curb outside T2.
Some travellers say Line 4 buses can park farther from the main exits of T1 and T2, meaning a 3–5 minute walk past the obvious bays used by Line 1 and other city lines. Expect to ask staff near the bus counters and signs in Chinese that list “4路机场专线” to find the correct stand.
Chinese comments often describe Line 4 and similar minor routes as “empty but infrequent,” so you might sit 20–30 minutes at the stand while a taxi would already be halfway into town. Staff at the airport sometimes redirect foreign passengers to the better‑known Line 1 even when Line 4 actually passes closer to their hotel, simply because Line 1 is easier to explain in basic English.
Regulars in Chengdu check real‑time bus apps like 高德地图 (Gaode/AMap) before deciding between Line 4 and a Didi, especially after 22:00 when headways can stretch. Locals also mention boarding at intermediate street stops on Line 4 rather than the airport terminus on the way back, skipping the longer loading time at CTU where bags and tickets slow everything down by another 10–15 minutes.
Step-by-step from arrivals
- 1. After landing at T1 or T2, follow signs to “Airport Bus / 机场大巴,” usually on the arrivals level within 5–10 minutes’ walk of baggage claim.
- 2. At the bus counter or ticket machine, ask for Line 4 (say “si lu, 4路”) and confirm the exact stop name near your hotel on a map; expect to pay around ¥10–¥20 in cash or by local mobile pay.
- 3. Walk to the specific bay listed for Line 4, which may be a few stands farther out than Line 1; check the front electronic sign on the bus for “4路” before boarding.
- 4. Keep an offline map with your stop starred and watch the live GPS dot, since audio stop announcements are usually only in Chinese and drivers may not speak English.
- 5. After getting off at your stop, move away from the curb and confirm your hotel’s walking route, as some suburban stops can sit 300–500 meters from major intersections.
Practical tip: Screenshot Gaode/AMap or Baidu Maps with your exact Line 4 stop name in Chinese characters before flying to CTU, then just show your phone to the ticket clerk or driver at T1 or T2 so you don’t end up on the wrong shuttle.
