DEAR TRAVEL TROUBLESHOOTER: I had a reservation through Airbnb for a three-day stay at a property in Washington, D.C., this past June. Before the stay, I contracted the COVID-19 virus and was unable to travel. In addition, two of my travel companions were in their early 80s and also unable to travel because they were in a high-risk group.

I contacted Airbnb and explained the circumstances. Fortunately, this fell under their extenuating circumstances policy. Airbnb allowed me to cancel the reservation and issued a $1,687 credit to be used during a future stay. It also told me that they would be temporarily locking my account reservation ability due to my positive COVID test.
