Empty Lines are hit and miss… It really depends on seniority. If you’re junior on your current BES (Base - Equipment - Seat) it’s better to take an SRL (50hour pay line - no flying option). As you get a little more senior in seat, Empty Lines can be a blessing, especially if you commute. Zero guaranteed pay for the month….but if you can risk it, you are are considered a “line holder” So you are eligible to pick up trips at ANY base by 1300 LOCAL BASE TIME. So you have to be proactive, but it can give you an opportunity to get trips you might not normally get as a reserve or very junior holder.

Good Luck!
