With the airport issues in Bangkok at the moment, I thought it may be helpful to let people know alternative ways of reaching Laos by air:
It is possible to reach Laos by the following international airports:
VIENTIANE:
Direct flights from Siem Reap, Chiang Mai and Kunming with Lao Airlines
Direct flights from Ho Chi Minh City and Hanoi with Vietnam Airlines
Direct flights from Kuala Lumpur with Air Asia
LUANG PRABANG:
Direct flights from Siem Reap and Chiang Mai with Lao Airlines
Direct flights from Hanoi with Vietnam Airlines
PAKSE:
Direct flights from Siem Reap with Lao Airlines
