Good point--to a point. As it is the company overloads them with minimal staffing, which is unfair to everyone. I flew a completely full 757 ATL-UIO, business class meal service in FC and hot meal in coach--all with four FAs. That's not fair to anyone, including the pax in the back who don't get anything for two hours.

In earlier eras, DAL staffed 757s with six FAs, then went down to five, now routinely staff with FAA mins of four. If the FAA allowed it I have no doubt that they would staff a 747 with one.
