We absolutely buy it. Emergency evacuation is EXPENSIVE and very few insurance companies cover it. You can buy medical/evac insurance separately from travel insurance if your CC covers travel delays, baggage, etc.
My coworkers' father is stuck in Argentina right now. He was bit by a bug...sort of a Zika type situation, but not Zika. He is on a ventilator and cannot fly home to get the care he needs without using an ambulance flight. The hospital he is in, and has been in for 47 days, is not equipped to heal him...just keep him alive. Their insurance is reimbursing them for their costs, but they have to pay upfront for his care. The insurance does not cover international medical flights. They do not have the $257,000 to pay for the flight home, so they have a gofundme and listed their home for sale to try to get him home. The other option is to leave him there til he dies from a lack of treatment. As a
travel agent, can I just say that the TOTAL cost for medical/evac insurance for his particular trip was less than $40 but he opted to not buy it because his credit card and health insurance covered him. Yeahhhhh.....
