Hi,
I've asked myself the same question. I did a bit of analysis, and I got the conclusion that it was not worth it to have 757's, for me, but as gazzz said, it depends on the market you are in. For me:
With 376/7/8/9 Im flying routes from 123nm to ~3000nm, with the flexibility of having aircraft from 114pax to 180pax, all on the same fleet group. True that on routes ~3000nm I keep getting the "These aircraft maybe to small for this route, etc", but the planes keep flying @90%-98% LF, so no problem for me there.
So taking the 752 on account @174,15,0 pax vs 739 @180,0,0 pax, with the last one been cheaper to buy and fly (not only consumes less fuel, it requieres less crew), turnaround and maintain, no reason to have 752 on my fleet. The only problem here is that 739 can fly at most ~2500nm, so I have to go down to 738 @162,0,0 pax, cause the 739ER is still not available on my GW. I don't have (and will not have) routes on the 3000-3900nm, that 752 can fly and 738 can't.
For 753 @222,15,0 pax 70min turnaround, flying up to~3300nm, fuel consumption of ~4000kg/hr, IMHO there is no point to compare to 737's. It can be compared to 763 @224,18,0 80min turnaround, up to ~4200nm, fuel @ 4800. 763 consumes ~33% more and cost 50% more to buy, so it looks like is a no brainer to have 763. But, again, the 767's fleet group gives a lot of flexibility, flying ~@210 total pax to ~@275pax and up to 6000nm. So, I would go for the 763 if there are just a few planes, cause I'wont open a 757 fleet group for a few planes. You could do a similar comparison vs A330/340, but in these case there is a gap btwn the ~180pax from the 737´s to the smallest A330 @258 (and A3XX are far more expensive)
But that's my reality, guess if you have a lot of routes on the ~2500nm to ~4000nm and 180-270pax (you could convert your planes to all Y seats, as domestic and regional routes in general don't have a decent C or F demand), it could be a good idea to have +10 to 20 757's and having a small fleet group would be compensated.
Just my two cents!
