What insurance?
My Nationwide Policy has added new language to my usual travel policy:
1) Hazard means:
c) Any delay due to lost or stolen passports, travel documents or money, Quarantine, hijacking, etc., etc.
2) The Company will pay for Reasonable Expenses incurred by You if Your Traveling Companion must remain Hospitalized
or if You must extend the Trip with additional hotel nights due to a Physician certifying You or Your Traveling Companion
cannot fly home due to an Accident or a Sickness but do not require Hospitalization.
[My emphasis added, in particular to the language requiring a physician's certification, which is an entirely different topic.]
When I searched InsureMyTrip for policies with such quarantine coverage, I found (among others) a policy from Trawick, which turned out to be a more expensive, rebranded wrapper for a similar (not quite identical) policy underwritten by Nationwide. The Trawick policy clearly was marketing the Quarantine coverage, whereas the Nationwide policy did not make it so apparent. But when I read the underlying policy, the less expensive Nationwide policy did cover quarantine expenses.
Moral of that story for me was:
1) Nationwide continues to be my go-to-first policy
2) read the fine print, sometimes you will find it to your advantage
Disclaimer: I have no affiliation with Nationwide, other than as an insurance customer for traveler's and other insurance, including many, many efficiently covered claims, with remarkable customer service.
