Can anyone tell me what the typical staffing is for an Airbus 319? Flight is about 5 hours.

Is it different for the Tanscon flights? If not, I believe it's three, isn't it, one in FC (who will usually help out in coach a bit) and two in coach.

They staff it with 3 F/A's most of the time. Sometimes they might add a 4th during holiday times, but with the mini-carts in the back, they feel they can efficiently service the aircraft with only 2 back there. These days I am sure the entire narrowbody fleet has minimum staffing.
