I have to laugh at this one. I started flying in a BE-99. They told us that paxs wanted pressurization. So the commuters got SA-227 and BE1900. Then they said those were too small and we needed a bathroom and a flight attentant. So we got DHC-8, SF340 and ATR's. Then we were told that passengers wanted jets, so we got RJ's. Now that most airlines have RJ's what do passengers really want? A cheap ticket
