Looks simple and reasonable. Not sure what other carriers are offering, and having to request a quote is annoying. Having extended coverage outside of Thailand would likely be preferable to most, I would imagine. I noticed hijacking was covered at 2,000 THB per each 12 hours of captivity.
I guess I missed this. There is a travel insurance scheme aimed at inbound tourists doing trips of up to 60 days and aged up to 70 years, starting at 650 baht and covering up to 1 million baht for medical expenses. You have to buy it online before arriving in the country. http://www.tourismthailand.org/ThailandTravelShield/ But I don't think this will solve the problem of irresponsible tourists turning up at hospitals with no insurance as they won't buy it anyway.
