Does a lawful permant resident need a passport to travel between puerto rico and the us by air?

Question

Possible trip to puerto rico in April just came about. I am a legal permanent resident, but i have refugee status so obtaining a passport is not an option at the moment because i'm applying for citizenship at the moment. I'm just afraid applying for a refugee travel document may arise some complications with my citizenship process. So would i be able to travel to and from puerto rico with my permanent resident card, plus other forms of id excluding a passport?
