I used Travelex and had a medical situation in Israel that they reimbursed with no problem at all. the medical is Primary, so there was almost no out of pocket, they were in touch with the hospital all the time and would have even flown us back on a medical jet if needed. And kids are on the plan for free with an adult. I agree that for cancelled tickets, baggage delay, etc, it is not worth it. Anyway many credit cards are covering that.
Some of the cards, CO pres, Penfed Amex and I think Amex plat, pay for medical transport if you need to get back to the US. (If you charge trip to the card) That's good because even if you have insurance in Israel, they are not paying to transport back, so if someone does need a hospital they are going to be in Israel for a long time.
