Both Vientiane and Luang Prabang have international airports. Both have taxis (Vientiane) or tuk tuks (Luang Prabang) waiting to take passengers after each incoming flight. Prices are set, and placards advertise what they are. From the airport to the centre of Vientiane town costs $5 and this small car will hold a maximum four passengers or three if you have even a moderate amount of luggage. If you’re really struggling for cash it is often possible to go out of the airport to the highway and flag down a passing share tuk tuk, which will cost around $2-3 per person, but the hassle, time and energy required make this an option only for those on the tightest of budgets. In Luang Prabang the only option is to take a tuk tuk to town at the set price of 50,000 kip ($5). These will take up to 5 passengers and the drivers will often do the work of finding other passengers if you are alone.
