"but probably not many more then the Bus."
Flew a320 Cap for two years and never made a fuel stop.
As a 737-300 Cap did one fuel stop, BOS - DEN.
The most restrictive 320 flight I ever did, fuel wise, was SNA - ORD in winter with fuel for alternate. Short runway and full pax load, still made it with a 30 minute hold for ORD. SEA - IAD? No sweat.
767 - 300 ferried fuel from IAD - LAX, full load of people and landed with 60,000 pounds of fuel on board. Someone thought it was cheaper to haul fuel one day to LAX.
737-900ER, from what you guys say, where's the ER part?

But, we get paid to fly em "safe" and someone else decides which airplanes.
