I bought it for a friend and want to give it to them but I will have to travel with the aged pecorino cheese for a couple of hours at room temperature before giving it to him. Is it safe to do so? It is about 150 grams and it is really aged and really airtight, wrapped in a thick plastic wrap (that is how I bought it from the store). 
Pecorino Romano can be stored at room temperature for weeks, even without vacuum sealing.  So you're fine.
