Exit only lanes

I have a question. Going north on the parkway has been pretty heavy flow of traffic at the Martin rd overpass, I’ve seen cars get on the airport road exit only and ride it all the way down to governors. Is this okay to do? I want to do it as well because it will get me to work on time but I don’t wanna be an a$$ hole. Is it considered being an a$$ if I use it in the mornings when everyone on the parkway is stopped?
