The planes are fairly new, but interior is not in great condition. Boarding process is a little confusing and way too much carry on really makes the boarding process more stressful than it needs to be.

What is good to know if travelling to Laos?

  • Luang Prabang is the ancient capital city of the Lan Xang Kingdom and a Unesco World Heritage site, with beautiful temples and gilded palaces on the bank of the Mekong River. Wat Xieng Thong is the most lavish temple with a tiered roof and gilded facades. The National Museum used to be the Royal Palace, built by the French in the 1900s and housing the gold-leaf-covered Phra Bang or “Holy Golden Buddha”. Climb the 300 steps to the summit of Mount Phousito see Wat That Chom Sii and for views of the city. If you visit the city very early in the morning, you can see the local people line up to give alms to the monks.
  • The nearby Pak Ou Caves – two caves, Tham Ting and Tham Phun, house Buddha images that have been left by followers over centuries.
  • Si Phan Don (or Four Thousand Islands) is a group of islands in the Mekong River in Southern Laos. The largest island is Don Khong.

  • Hundreds of giant stone jars – some more than 3 metres high – are scattered around the Plain of Jars in north-central Laos.
