The question is quite unclear, maybe do you have a booking reference from travel agent but not yet your "official" ticket? Just go on Etihad website and enter "Manage my booking" you just insert the PNR code printed in your email/travel agent confirmation (hope you have any) and your Surname, your booking will appear and then you have the option to download/print or email your ticket and itinerary. It should work either booked directly on EY or even trough a travel agent.
