Question
Sometimes I travel by airplane with a carry-on only and no checked luggage. Included in my carry-on are my tefillin and siddur. Airport regulations prohibit leaving luggage unattended or with a stranger. What is one supposed to do if they have to use the restroom at the airport, but their tefillin and siddur are in their luggage that must be kept with them and therefore brought into the restroom?

Question
HI. I recently made a car rental reservation for an upcoming trip. I only have to pay when I pick up the car and can cancel the reservation before that. I then found a lower price with another company. Can I make a reservation with the 2nd company but still keep the first one, just in case there is an issue with the 2nd company when I get there?

Question
Dear Rabbi, Is there a problem with a kohen flying on a plane transporting a dead body? Truth is, passengers usually don’t know the plane has one. The one time I found out was when a plane I was on landed and they announced they were stopping to ceremoniously drop off the body of a soldier killed while on duty. That soldier was not likely Jewish. But all airlines, El Al included, do transport corpses, usually without letting passengers know.

As a vegan, I was wondering if there is any way to make a kosher vegan mezuzah? Is it dictated by Jewish law (not simply tradition) that it must be written on animal parchment?
