I guess it depends on the operator .. about 10 years ago I flew Bangkok to Vientiane and back a month or two later .. ... interesting to say the least .. I managed one and half jumpseat sectors ... not quite what I would describe as a "modern" airliner .. but very forgiving from what I saw .. of great interest was the observation that the crew, apart from the variable English .. wasn't much different to the people I had flown with in the past ... just like being at home ..
