While organizing for Pesach I came across a blanket that someone gave us that has a tag on it which says: “Property of American Airlines Please Do Not Remove From Aircraft”.
What am I supposed to do with it at this point in time?
Is there any Kiddush Hashem at this time, or the opposite?
Under the circumstances, the method of returning the blanket is a little unclear, and the element of Kiddush Hashem is unclear.
Although there is no formal obligation to do so, I would perhaps take the blanket along the next time you fly, and bring it back to the airline desk, explaining that you were given the blanket and noticed that it is airline property.
