Last time, I used allianz.
My travel was not to Europe Schengen area.
I checked these company covers world wide.
Also I had no trouble while traveling, so I made no claim.
Anyway, I will use one of these on my nest travel.
According to Thai air site, office in Phuket is this.
I have never visited this company.
I am not sure if the company is operated by Thai air
or just have contract with Thai air.
Maybe worth sending e-mail or making phone call?
