KK STAR Airport Express is a premium bus network with services focusing mainly on bus transport to Phnom Penh International Airport. The KK STAR Airport Express plies the following routes:
Airport Express Red Line
Phnom Penh International Airport – Dara Airport Hotel – President Hotel – Sunway Hotel – Raffles Hotel le Royal – Sisowath High School – Toyoko Inn (and return by the opposing direction)
Airport Express Orange Line
Phnom Penh International Airport – InterContinental Hotel – Sihanouk West Street – Sihanouk East Street – Naga 2 – Naga 1 – Toyoko Inn – Sofitel (and return by the opposing direction)
Airport Train Shuttle Line
Phnom Penh Railway Station – Wat Phnom – Central Market – Sisowath High School – Independence Monument – Naga 2 – Royal Palace – Night Market – Mekong Express Bus Station – Phnom Penh Railway Station (one way loop service)
Sihanoukville Intercity Line
Phnom Penh International Airport – Rest Area – Sihanoukville Airport – Sihanoukville Mekong Express Bus Station – Onederz Hostel – Sokha Hotel – Independence Hotel (and return by the opposing direction)
For the Airport Express Red Line, Airport Express Orange Line and Sihanoukville Intercity Line, KK STAR has a counter at the Phnom Penh International Airport transportation desk located in the arrival hall.
You can purchase the bus ticket at this counter. One way tickets to Phnom Penh city costs USD5 while one way tickets to Sihanoukville costs USD15.
The bus will wait at the driveway near the counter once ready.
For the Airport Train Shuttle Line, KK STAR has a counter beside the Royal Railway ticket counters. However, the counter wasn’t staffed during my visit.
Nevertheless, I suppose you could buy a ticket from the driver if the bus has arrived.
The KK STAR Airport Express is a good complement to the Royal Railway Airport Shuttle Train, providing an alternative to the airport should you have missed the train or to continue to other destinations around Phnom Penh city from Phnom Penh Railway Station.
However, with ticket prices on the high side, it may be better to stick with the Phnom Penh City Bus network or even just Grab around with the free rides worth KHR 12,000 for trips beginning or ending at Phnom Penh Railway Station with the promo code of GRABTRAIN.
