Getting to China's ancient capital is not the everyday direct route that Shanghai or Beijing is. Some seasons have a non-stop; others mean connecting through a hub. This guide helps you weigh every option, find the best fare, and plan the ride into the city from Xianyang Airport before you ever hit "book".
Here's the honest starting point: Bangkok–Xi'an does not have the dense menu of non-stops you get to Shanghai or Beijing. Xi'an sits inland in north-central China, so direct flights come and go with the season. At the time of writing, Spring Airlines (9C) flies direct from Suvarnabhumi to Xianyang in about four hours, while Thai AirAsia X — which used to fly direct from Don Mueang — suspended the route temporarily from May to October 2026 as fuel prices climbed.
Because of that, it's worth planning Xi'an with two paths in mind at once: fly direct if it runs and the timing suits you, or take a one-stop routing through a China hub such as Guangzhou, Kunming, Chengdu or Hong Kong — which often gives you more departures to choose from, and sometimes a better fare. Schedules on this corridor shift frequently, so check current flights before you lock in dates. Don't plan around last year's timetable.
One thing that makes the trip easier: Thai passport holders currently enter China without a visa for tourism, and Thailand and China share a time zone — you land and start your day with no jet lag at all. Verify the latest visa conditions before you travel, since policy can change, in the visa-free entry guide for Thai travellers.
Xi'an schedules change seasonally and shift more often than the big gateways — verify current flights before booking.
| Airline | Type | Routing | What's included | Notes |
|---|---|---|---|---|
| Spring Airlines (9C) | Low Cost | Direct, Suvarnabhumi (BKK) → Xianyang (XIY) | Base fare only — all extras charged separately | The main direct option at the time of writing — about 4 hours. Low base fare, but add baggage, seat and meal before you compare. |
| China Southern (CZ) | Full Service | One-stop via Guangzhou (CAN) | Checked bag + meal + seat selection | The Guangzhou hub has the most frequency. Bangkok–Guangzhou ~3h 45m, then Guangzhou–Xi'an ~2.5h, several times a day. |
| China Eastern (MU) | Full Service | One-stop via Kunming or Shanghai | Checked bag + meal + seat selection | A large network with several connecting hubs. Compare layover times on each routing before you choose. |
| Air China (CA) | Full Service | One-stop via Beijing or Chengdu | Checked bag + meal + seat selection | The flag carrier, with hubs at Beijing and Chengdu — handy if you want to fold a second city into the same trip. |
| Cathay Pacific (CX) | Full Service | One-stop via Hong Kong (HKG) | Checked bag + meal + seat selection | Polished service and an easy transfer in Hong Kong — good if you want to break the trip there, though a longer way round than a mainland hub. |
| Thai AirAsia X (XJ/FD) | Low Cost | Direct, Don Mueang (DMK) → Xianyang (XIY) | Base fare only — all extras charged separately | Previously flew direct from Don Mueang, but the route is suspended 11 May–23 Oct 2026 over fuel costs. Check whether it has resumed before planning around it. |
Because direct flights to Xi'an come and go, knowing both paths keeps you flexible and stops you missing a good fare.
If a non-stop runs on your dates (for example Spring Airlines from Suvarnabhumi), this is the fastest and most comfortable way to go — one flight, no dragging bags through a transfer, no praying your connection isn't delayed. Especially worth it if you're travelling as a group, with older relatives, or with young children.
The path with the most departures to choose from — and often a good fare. The highest-frequency connection is via Guangzhou with China Southern: Bangkok–Guangzhou ~3h 45m, then Guangzhou–Xi'an ~2.5h, several times a day. Total door-to-door is roughly 8–10 hours depending on the layover.
Xi'an has a single airport; international flights use Terminal 5, which opened in 2025.
Xi'an's only airport, about 40 km northwest of the city. Terminal 5 opened in February 2025 and handles both domestic and international flights on a single level, so transfers are easy on foot. It even has a small museum displaying Tang-dynasty artefacts unearthed during construction.
Some direct departures from Bangkok leave around 3 am and land at Xianyang in the early morning (about 7–8 am) — which is actually a bonus, as you get a full first day. But if a connecting routing arrives late, check the Airport Line's last train and confirm your hotel check-in in advance in case you need a taxi.
A direct Bangkok–Xi'an flight takes about four hours (roughly 3h 55m), much like flying to Hong Kong or Taiwan — not a long haul. Connect through a China hub and total travel time stretches to around 8–10 hours, depending on the layover. The nice part of this route is the shared time zone: you step off the plane and get on with your day, with no jet lag to fight.
Full-service carriers like China Southern or Cathay Pacific include a meal, seat-back entertainment and a checked bag in the fare. Spring Airlines is a low-cost airline — narrower seats and everything charged separately — which is fine for four hours, but if you're travelling as a family or carrying heavy bags, run the all-in numbers before you decide.
Three main options cover the 40 km from Xianyang to the centre. The Airport Line (Metro Line 14) runs to Xi'an North station (北客站), where you transfer to Line 2 or 4 into the heart of the city — cheap and traffic-proof. The airport bus costs ¥25–30 and takes about an hour to the Bell Tower / central railway station area. A taxi or DiDi runs ¥120–150 and is the easiest if you have heavy bags or a group.
Thai passport holders currently enter China without a visa for tourism — confirm current conditions at our visa-free guide before you fly. Download and set up Alipay and link your card before departure: Xi'an runs almost entirely on QR-code payments, including Metro gates and buses. Standard roaming SIMs work, but Google, Instagram and most Western apps are blocked — if you need them, set up a VPN before you enter the country (it can't be downloaded once you're inside the firewall).
Lovely weather and blossom in Xi'an. Fares are mid-range — but China's Labour Day holiday in early May pushes prices up and fills hotels fast. Book the week either side if you can.
Genuinely hot, often 35–40°C. Fares run mid-to-high as Chinese school holidays drive demand. The Terracotta Army under a midday sun is brutal — bring water and shade.
The season most travellers recommend. Clear skies, comfortable temperatures, perfect for walking the city wall all day — except Golden Week (October 1–7), when prices hit their annual peak.
The cheapest time to fly, outside Chinese New Year. Cold, sometimes below 0°C, with thinner crowds and crisp photos — but Chinese New Year sends fares and crowds sharply higher.
Xi'an is a major high-speed rail hub for central China. Once you've landed, the train from Xi'an North station (西安北) beats domestic flying in plenty of cases: Mount Huashan is about 30 minutes away, Luoyang (for the Longmen Grottoes) around 1.5 hours, Chengdu 3–4 hours and Beijing roughly 4.5 hours. It makes a natural pairing to combine Xi'an with Luoyang in a single trip.
