Flights Bangkok to Phnom Penh (BKK-PNH): Airlines, THB Fares

Bangkok to Phnom Penh is one of the shortest international routes out of Bangkok — a one-hour hop to Cambodia’s capital. It runs on a steady mix of business travel, tourism, regional family ties and onward connections, with around 21 flights a week keeping it frequent.

Block time is barely an hour, short enough that the airport time outweighs the flight. With a mostly low-cost line-up, the route behaves like a regional bus service — easy availability, and a decision that comes down to timing and the all-in fare.

Airlines on this route

Three carriers fly BKK-PNH: Thai AirAsia and Thai Vietjet on the low-cost side, with Cambodia Angkor Air covering the route as well. The low-cost carriers price the base seat low and sell baggage, seats and meals separately; on a flight this short many travellers fly cabin-baggage-only. When comparing fares, the figure that matters is the total once whatever baggage you need is added.

Fare trends

BKK-PNH fares are low and competitive, kept that way by the short distance and the low-cost line-up. The cheapest seats are the early-released fares — booking two to five weeks ahead usually lands a good THB price, and mid-week departures undercut weekends. Demand rises around regional holidays. For a hop this short, travelling light is the simplest way to keep the cost down.

Seasonality & best time to book

Bangkok–Phnom Penh fares move with demand. The cheapest windows fall outside school holidays, Songkran and New Year; book 4–8 weeks ahead for normal dates.

About Phnom Penh

Phnom Penh is the capital of Cambodia, set where three rivers meet — a city of riverside boulevards, the Royal Palace grounds, markets and a number of significant historical sites. It is compact and walkable, and inexpensive on the ground. For travellers from Bangkok it works as a short city break and as a starting point for travel onward across Cambodia, including the connection toward the Angkor temple region.
