Air
Pleiku's tiny airport is located 5km north of the city center and has flights with small airplanes (ATRs, Fokkers) to Ho Chi Minh City, Hanoi, and Da Nang.
A xe om from the city center is likely to take 30,000d, a taxi should be between 50 and 100,000d. You're unlikely to find any xe oms on arrival in Pleiku airport. If you want to save money, you could walk or take a taxi to the main road and take a bus from there (buses from the north - Kontum, Da Nang etc - pass by there). Turn left as you leave the airport building and walk along the barracks
