It is about half a day in the air from Suvarnabhumi to China's capital — but Beijing has two airports on opposite sides of town, and cheap nonstop fares are scarcer than you might expect. This guide tells you which carriers fly direct, which connect, and how to book so the price actually makes sense.
Beijing is noticeably further from Bangkok than Shanghai, but the route still has daily nonstop service. The full-service carriers flying direct to Capital Airport (PEK) almost every day are Air China (CA), Thai Airways (TG) and Hainan Airlines (HU). Meanwhile China Eastern (MU) and the low-cost option Thai Vietjet (VZ) fly nonstop into Daxing (PKX) on the south side of the city — a different airport entirely, and getting that wrong can add an hour to your transfer.
The big difference from the Shanghai route: Beijing has far fewer "cheap nonstop" choices. Fares that look unusually low are usually one-stop connections (Juneyao via Shanghai, for example), which add several hours door to door. Return economy nonstop fares generally land around ¥2,000–4,500 (roughly ฿10,000–22,500), depending on season and lead time. The good news: as of 2026, Thai passport holders can enter mainland China without a visa for tourism — verify current conditions before you travel, since policies can change.
One thing that makes Beijing easier: Thailand and China share a time zone, so you step off the plane with no clock to reset and no jet lag. See the full picture of the city and where to stay in our Beijing city guide.
Schedules change seasonally — verify current timetables, and check carefully whether a fare is nonstop or connecting.
| Airline | Type | Lands at | Routing | Notes |
|---|---|---|---|---|
| Air China (CA) | Full Service | Capital (PEK) | Nonstop, daily | China's flag carrier, with its main hub in Beijing — the most frequent service on this route, often on a Boeing 777. |
| Thai Airways (TG) | Full Service | Capital (PEK) | Nonstop, daily | Thailand's flag carrier from Suvarnabhumi. Full-service with checked baggage and a meal included in the fare. |
| Hainan Airlines (HU) | Full Service | Capital (PEK) | Nonstop, daily | A well-rated Chinese carrier flying nonstop almost as often as Air China, frequently at competitive prices. |
| China Eastern (MU) | Full Service | Daxing (PKX) | Nonstop (less frequent) | Flies nonstop into Daxing, the newer airport to the south. Confirm you are landing at PKX, not PEK — the transfer routes differ. |
| Thai Vietjet (VZ) | Low Cost | Daxing (PKX) | Nonstop (less frequent) | The main budget nonstop option on this route. Low base fare, but baggage, seat and meals are extras — total them up before comparing. |
| Juneyao / China Southern, etc. | Mostly 1-stop | PEK or PKX | One stop | Usually route via another city (Juneyao via Shanghai, for instance). Cheaper, but several hours longer overall — worthwhile only if price beats time. |
Beijing has two major airports on different sides of the city. Flights from Thailand use both, depending on the airline.
Beijing's main airport, to the northeast and closer to the centre. Most nonstop flights from Thailand — Air China, Thai Airways, Hainan — arrive here, and it has the widest choice of transfer options.
The striking Zaha Hadid-designed airport that opened in 2019. The terminal is spectacular, but it sits well to the south — considerably further from the centre than PEK. Nonstop flights from Thailand landing here are China Eastern and Thai Vietjet.
A direct Bangkok–Beijing flight runs about 5.5 to 6.5 hours. The fastest nonstop into Capital (PEK) is around 4 hours 40 minutes; routes into Daxing (PKX) tend to take a little longer, depending on winds and routing. Daytime departures often track over the central Chinese interior, and on a clear day the scale below is worth a window seat. Some Bangkok departures leave after midnight and land in Beijing in the early morning — plan your ground transfer for that arrival time.
On full-service carriers — Air China, Thai Airways, Hainan — expect a hot meal, a personal entertainment screen and a checked-bag allowance, often aboard a wide-body Boeing 777 with comfortable seating. On Thai Vietjet, the flight time is similar, but this is a long sector for a budget cabin — if you are travelling as a family or with luggage, weigh the all-in price and the comfort before deciding.
If you land at PEK, the Airport Express (¥25) connects quickly to the city Metro, and a taxi runs ¥90–120 — handy with heavy bags. If you land at PKX, take the Daxing Airport Express (¥35) to Caoqiao station and change to Line 10, or a taxi for ¥150–200, which takes longer because the airport is further out. Plan around whichever airport your ticket names.
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 before departure and link your card: Beijing runs almost entirely on QR-code payments, including the Metro and restaurants. Standard roaming SIMs work, but Google, Instagram, LINE and most Western apps are blocked — if you need them, set up a VPN before entering the country (it cannot be downloaded once you are inside the firewall).
Beijing warms up and turns pleasant — a good time to visit, with mid-range fares. The Labour Day holiday in early May pushes prices up and fills hotels, and the very start of spring can bring occasional dust storms.
Hot, with some rain. Fares run mid-to-high as Chinese school holidays drive demand, and hotel rates climb. The main sights get crowded — worth going, but price the whole trip carefully.
The season most experienced Beijing travellers recommend: dry, crisp, clear skies and turning leaves. Fares are reasonable — except for Golden Week (October 1–7), when prices hit their annual peak.
The cheapest time to fly outside Chinese New Year, but Beijing winters are genuinely cold — often below freezing, sometimes with snow. The Great Wall under snow is stunning if you pack for it. Chinese New Year sends prices sharply higher.
With the ticket sorted, the next step is choosing a hotel that matches your airport and the part of the city you want to explore. For sightseeing-heavy first days, somewhere central near the Forbidden City and Wangfujing is most convenient — but if your flight lands late or leaves early, a hotel near Capital Airport saves real time on transfers.
