One of the first blogs that I did when I started travelingbug.org was about traveling to Angkor Wat which is located in Cambodia. One of the ways that I mentioned on how to get there was to fly Siem Reap airlines. I read a recent post about this airlines that is not very good news for anybody using this company.

The European Union has recently banned all flights from Siem Reap airlines into the EU. They said it had to deal with safety concerns. I would highly recommend to find another way to get to Siem Reap other than use this company.
Safe travels
