Big news if Thailand is on your 2026 bucket list: starting mid-2026, the Thai government will require every international visitor to show proof of travel insurance when applying for the ETA (Electronic Travel Authorization). Minimum coverage: approximately €10,000–20,000 for medical care, emergency surgery and medical repatriation. No insurance = no entry. The good news? If you already buy decent travel insurance, you’re probably covered. I’ll walk you through what to look for, which policies actually meet the rule, and how to avoid being that person who gets sent home from Bangkok airport.
