<p>I think it is 28X. It is free to Pitt students with ID but anyone can ride it by paying the fare.</p>
<p>@vryproudmom - He is offically registered in those classes. I actually rented a car for $ 50 for the 2 days - that was cheaper than taking a cab back and forth and much more convenient.</p>
<p>Thanks so much everyone for the replies. If I want to look up the bus schedule from the airport, bus station, and train station is it just Pittsburgh transit?</p>
<p>Google Pittsburgh Port Authority. It has schedules and fares.</p>
