Let me start off by saying hello to all you fellow airwaysimmers. =)
The seemingly age old question of Airbus vs. Boeing now has somewhat of an answer. I want to remind you all that this is out of my own research and may not be 100% accurate. I also cannot account for differences in how an aircraft is operated between different carriers, this is as generic as it gets. One other side note, all aircraft are presented in configurations capable of 2000nm and all are represented with new pricing. Aircraft age, condition, and price greatly affect the cost of the aircraft, but you can find deals and lower the cost of operation even below levels of a new aircraft. Hopefully some of you might be able to decide after reading some of this.
120-130 Seat Aircraft
In the 120-130 seat range, in standard seating configuration, the A319-100 edges out the competition because of its relatively low fuel burn rate and maintenance costs. With the CFM56-5A +6.0tn MTOW, it will burn 2200kg/hr of fuel at 450kts and travel 2460nm. This package new will cost $827790/month. Together with maintainance costs it comes out to $37013.91/day. The 737-300 will cost $35656.95/day, but also burns 200kg/hr more fuel and flies 26kts slower leading to the slight edge for the A319. Obviously the shorter the route the less significant the costs become.
In overall cost to operate, the A318 takes the cake at $34102.18/day, 2020kg/hr fuel burn and 2460nm range with the PW6122A +9.0tn MTOW. Of you plan on adding some C-class seats or a high-density configuration, especially at longer ranges, the A318 may be the best aircraft for the job.
The 737-700 seems to have priced itself out of the market at $39892.37/day.
150-165 Seat Aircraft
Now to the 150-165 seat range, the B737-400 is the cheapest to operate under a lease. With the CFM56-3B2 +1.8tn MTOW, the B734 burns 2830kg/hr of fuel at 424kts for 2000nm, all at a daily cost of $37059.10. It is also the cheapest aircraft in this size category to operate overall.
For those of you directly purchasing one of these 150-165 seaters, the A320-200 with CFM56-5B4's, Standard, is the cheapest to operate maintenance-wise at $10517.64/day. The fuel burn is only 2390kg/hr, it flies at 450kts for 2330nm.
Again the 737NG did not fair too well, the 737-800 costs $43,592.97/day to operate and more than $11500.00/day in maintenance costs alone.
Hope this helps =)
