If you have 150 pax, you can either use 3 RJ's or one 737...the 73 will burn far less fuel and cost less to buy and maintain than 3 RJ's.

The only downside to the 73 is frequency...the pax have one flight schedule per day instead of three. This is a big deal, and it was one of the driving forces bheind the rise of the RJ...but with fuel prices where they are, the airlines are not as worried about frequency.

Rough numbers (cruise):

737-7: 5,000 lbs/hour
CRJ 200: 3,000 lbs/hour
