How do I get my airline ticket?

I am doing a study abroad program and the travel agent we are all using sent us an email with our flight itinerary. I don't really know anyone else in the group so I can't get a hold of them. All I can find is the flight itinerary like I said, and the ereceipts of the tickets. This is the first time I've flown, usually my parents take care of the tickets and they have no idea either. Any suggestions its Wabba Travel is that helps. Basically where do you print the tickets usually and maybe my professor will have them at the airport. He is always unreachable I have called him and emailed him multiple times so that isn't an option and I don't want to find out once I get to the airport that he does not have my ticket.
