Daily Halacha - Guidelines for Travelers, 27th of Sivan 5777

Is a Kohen permitted to fly on an airplane when there is concern about impurity from the dead on the plane?

A Kohen is permitted to fly on "El Al" airplanes, even though coffins are placed inside the aircraft. Similarly, a Kohen is permitted to drive his vehicle on roads very close to Jewish graves [Responsa of the Rishon LeZion 1, p. 367].

Is there an obligation to purchase products specifically from a Jewish seller?

When buying or selling an item, one should sell to or buy from a fellow Jew rather than a non-Jew, unless there is a significant difference in price or quality. Buying from or selling to a Torah scholar takes precedence over buying from or selling to an unlearned person [Rema 156:5 and Pitchei Teshuva 6].
