Yep. You report to your crew base on your first scheduled workday. If you have an airplane there, you might go right to it, but that's not common. More often than not, they'll buy you an airline ticket to an uncrewed airplane, but this is all part of your duty time. (So if the flight's oversold, cancels, or whatever, you're not stressing a commute. You're already at work; it's not your problem! Much lower-stress than commuting space-available, that's for sure.)
