Considering we don’t oversell flights and the vast majority have 5-10 open, worrying about Cabin jumpseats is pretty far down the list.
Most all of our older 320s have 2 cockpit jumpseats. It’s been awhile since I flew a 319, but obviously at least one.
When I was LAX based we had a decent amount of jumpseaters from BOI and BIL it seemed. Never had anyone up front with us, as they had a seat in the back.
I’m honestly not even familiar with a cabin jumpseat. Is that an MD-80 thing?
