Diatomaceous earth is very messy and slow. A quick search tells me hotels usually do heat treatment. It requires a professional (or in house set up). I suspect they also wrap the mattresses by default, but I'm not sure that's strictly a bed bug measure. Bed bugs are everywhere though. They will infest any public space with furniture, or any space like hotels where anybody can come in and out. They have infested my local movie theaters (at least the older ones). I bet there are a lot of airlines with this issue.
