Go there a day earlier and check it out in person. There is a 90% that it will be in the same place the next day.
This depends a lot on the airline and the airport but unless the airline has a major presence in the airport, it's allocated dynamically. As long as the flight schedules don't change much, the allocation doesn't change that often but it DOES change.
You can try calling the airport or the airline but chances are they want know (or care) either.
