Our original flight on Angkor air was cancelled so we were changed to Lanmei which unlike many of the reviews posted, did take off on time. The flight was good and the seating was up to normal standards.
Our big problem is that when we checked in our two suitcases weighing 37 kilo we were advised we have a 15 kilo limit and that will be 21 US dollars extra. We have traveled extensively and cheap airlines like Ryan air and German wings etc. have these policies but then their fare is cheap.
Lanmei's fares are not cheap and they want to rip of the tourist with these luggage restrictions unlike Vietnam Air, Angkor Air and others flying out of Siem Reap.
Be warned and don't fly them unless you have to unless they come in to line with their baggage allowance.
