A colleague of mine recently reached out to me. I asked if he would like to meet up sometime to which he notified me that he would be traveling the remainder of this week. In what context is it okay to use the expression safe travel or safe travels? Does it depend on the method of travel (seeing as for flying this could come off as ominous)?
Thank you for your quick reply.
Safe Travels,
John Doe

"[I wish you] safe travel." uses the uncountable form of the noun. It refers to an amalgamation of all of the travels one might undertake in the specific time period.
"[I wish you] safe travels." uses the countable noun. We understand that a number of separate travels will occur, perhaps in a single trip with stopovers.
EDIT
A better known phrase is "Travel safely!" This is a friendly imperative. You'll find lots of examples online. Try searching Google Images for example.
