How do airlines stop it going to both?
At booking you will be asked to enter a frequent flier program number. If you wish to credit to UA, enter your Mileage Plus number.

Note that MP credit on EI is limited. Details are here: http://www.united.com/CMS/en-US/mark...spx?ItemId=438

I might ask why you would consider booking through Orbitz. It is almost always better to book directly with the airline.
