• AIG / Travel Guard — Very customizable plans and add-ons (medical, cruise, adventure bundles); historically a top pick for breadth of options. (Note: Travel Guard’s ownership/brands have shifted in recent years — check the provider page at purchase.) (forbes.com, cnbc.com)

Useful comparison sites

Quick buying tips (what to check in any quote)

• Primary vs secondary emergency medical: primary pays the travel insurer first (faster), secondary requires you file with your regular health insurer first. Choose primary if you have no U.S. international coverage or want faster settlement. (squaremouth.com)
• Medical-evacuation limits: prioritize high evacuation limits (many experts recommend $100k–$500k+ depending on location/activities). (squaremouth.com)
• Pre-existing-condition waiver: if you or a close relative have recent medical issues, buy within the insurer’s required window to qualify for the waiver. Policies differ (10–21 days common). (insuremytrip.com)
• “Cancel for any reason” (CFAR) is an optional upgrade that reimburses part of trip cost if you cancel for a non-covered reason — useful but more expensive and often must be bought soon after your initial deposit. (forbes.com, cnn.com)
• Read exclusions carefully (adventure sports, pregnancy, pre-existing conditions, electronics theft, shipping claims, etc.) and confirm whether coverage is primary/secondary and whether assistance is 24/7. Editorial reviews note claims/customer-service experiences vary by company — so check recent reviews in addition to policy wording. (businessinsider.com, consumersadvocate.org)
