Quick answer
China's budget airlines — Spring Airlines (春秋航空) above all — sell domestic fares from CNY 200–500 on the right dates, roughly half the full-service price on the same route. The catch is unbundling: 7 kg cabin bag included, checked baggage from about CNY 120–250 online, and nothing else free. Buy the add-ons at booking, not at the airport. Last verified: 2026-10-11.
Why budget airlines matter in 2026
China's high-speed rail owns routes under about 1200 km, but the country is enormous: Chengdu to Urumqi is 2500 km, Shanghai to Harbin 1700 km, and even the HSR takes 8–13 hours there. Low-cost carriers fill that long-haul gap and the price-sensitive leisure routes. Spring Airlines, the pioneer, has run since 2005 on a single A320-family fleet with fares that routinely undercut the full-service carriers by 30–50%. For a traveler crossing two time-zone-sized distances in one trip, one well-bought LCC flight saves both a day of rail time and CNY 400–800.

- Cabin allowance: typically 7 kg, one piece; Spring's standard fares include no free checked bag
- Checked baggage online: about CNY 120–250 for 20 kg at booking — airport counter prices run much higher
- Seat pitch: 29–30 inches on Spring's single-class A320s
- Check-in cutoff: counters close 40–45 minutes before departure on LCCs
- Booking: airline apps, official WeChat mini-programs, or Trip.com for English support and foreign cards
The carriers, one by one
Spring Airlines (春秋航空)
The model: one economy class, 29–30" pitch, no free meals (buy a CNY 25–40 boxed meal onboard), aggressive 200–400 yuan flash fares on routes like Shanghai–Chengdu or Shanghai–Xi'an. Cabin 7 kg; buy 15–25 kg checked allowance online at booking. Its route map is the widest of the LCCs, including international hops to Japan, Korea, and Southeast Asia.
The regional LCCs
9 Air flies from Guangzhou north and west; West Air works the Chongqing hub; Lucky Air and Colorful Guizhou run Yunnan and Guizhou spokes; Urumqi Air covers Xinjiang distances no one wants to ride a train across. Rules mirror Spring's: bare fare, paid bags, paid food.
The fare math, done honestly
A Shanghai–Chengdu example: full-service economy around CNY 1200–1600 walk-up, LCC fare CNY 450–700, plus CNY 150–250 for a checked bag and CNY 30 if you want the sandwich. Still CNY 400–700 saved — unless you show up at the airport with an unbooked 20 kg suitcase, where the counter charge can erase the entire gap. The second honest number: full-service fares drop to CNY 600–900 in sales, so a price check on the same dates is worth 5 minutes.
Booking as a foreigner
- Trip.com — English interface, foreign Visa/Mastercard, same inventory as the Chinese apps, clear baggage add-on display.
- Airline apps and mini-programs — cheapest add-on prices, but Chinese-language flows and mostly UnionPay/Alipay payment.
- At booking, buy the bag — 20 kg online costs about CNY 120–250; the same allowance at the airport counter can cost 2–3 times that.
- Passport as ID — enter the passport number exactly as on the document; that is the boarding identity at the gate.
Costs and pricing breakdown
- Typical LCC fare, popular routes: CNY 300–700
- Flash-sale fares: CNY 200–400 (Shanghai–Chengdu class routes)
- 20 kg checked bag, online: about CNY 120–250
- Same bag at the airport: frequently 2–3x the online price
- Onboard meal: CNY 25–40
- Seat selection: CNY 20–60 if you care where you sit
- Full-service comparison fare: CNY 600–1600 on the same routes
Pitfalls to avoid
- Buying the bag at the airport: the single most common LCC money leak — online-at-booking is the cheap channel.
- Weighing nothing before you leave: 7 kg cabin enforcement is real; a jacket pocket of camera gear gets measured.
- Confusing Spring with a full-service carrier: no free water refill beyond the initial service on some flights, no rebooking flexibility on the cheapest buckets.
- Cutting check-in to 30 minutes: counters close 40–45 minutes out and enforce it — budget airlines do not hold planes.
- Booking the wrong airport: Spring uses secondary fields (e.g., Shanghai Hongqiao, sometimes Pudong; Chengdu Tianfu vs Shuangliu) — check the code before booking a same-night connection.
Alternatives and trade-offs
- Full-service sales: China Eastern, Air China, and China Southern match LCC prices off-peak with 20–23 kg checked included — check them first on any route.
- High-speed rail: under 1200 km, the train usually wins on total time; over 2000 km, the plane wins outright.
- In-between carriers: Hainan Airlines and Juneyao sell semi-bundled fares — dearer than LCCs, cheaper than the majors.
- Mixing modes: fly the long haul (Chengdu–Urumqi), rail the corridors (Xi'an–Luoyang) — the standard China itinerary pattern.
Local context and customs
LCCs taught a generation of Chinese students and factory workers to fly — cabins fill with first-time flyers, so gate crews are brisk and helpful about the process. Bring your own water bottle through security (fill it airside; fountains are at every gate area) and snacks from a convenience store; onboard sales are the airline's profit engine. Seats do not recline much on Spring's Airbus fleet — 30 inches is a sit-up flight, comfortable for 3 hours, a negotiation for 5.

Putting it all together
Spring Airlines and its peers cut 30–50% off long domestic routes if you play their game: book early, buy the 20 kg bag online for CNY 120–250, respect the 7 kg cabin limit and the 40–45 minute check-in cutoff, and eat before boarding or budget CNY 30 for the meal box. Under 1200 km, take the train; over 2000 km, let the LCC do it for the price of two rail tickets. Last verified: 2026-10-11.
FAQ
Is Spring Airlines safe?
Yes — it operates a single A320-family fleet under the same CAAC safety oversight as every Chinese carrier, with one of the youngest fleets in the market.
What is included in the fare?
The seat and a 7 kg cabin bag on most LCC fares. Checked baggage, meals, and seat selection are add-ons — cheapest when bought online at booking.
How much is a checked bag?
About CNY 120–250 for 20 kg when bought online in advance; airport counter prices can run 2–3 times that.
Can foreigners book these airlines?
Yes — through Trip.com with foreign cards, or the airline apps if you have Alipay/WeChat Pay set up. The passport is your ID at check-in.
How early should I arrive?
Counters close 40–45 minutes before departure on LCCs and will not reopen. Arrive 90 minutes ahead for a domestic flight.
LCC or high-speed rail?
Under 1200 km, the train usually wins door to door; over 2000 km the flight wins outright. Between the two, compare against same-day full-service fares.
Is food served?
Not free — buy a CNY 25–40 meal box onboard, or eat before and bring snacks through security.
What about refunds and changes?
The cheapest fare buckets are restrictive: changes carry fees and refunds are partial at best. Only buy the flash fare when the date is certain.
