i think Lao students who study in china usually buy the Lao airline ticket from Vientiane-Kunming, because they got discount ! i have no clue how does it cost for one way ticket now?
why is chines eastern airline going to add a new flight from Kunming to Vientiane?, i think because now chines businessmen travel a lot to Laos and now many chines tourisms choose Laos to be their destination on the holiday.
