UPS 757 Info

Hi all,

Just out of curiosity, what is the structural MTOW of both the PW & RR 757s at UPS? I'm curious because I've seen some numbers found via google that say they are as low as 210,000 lbs. Has UPS paid Boeing for higher weights?

On that subject, is there any airports that the 757 runs into Runway/Climb limit restrictions or is usually just S-MTOW and/or Landing-MTOW?

While were at it, how about MZFW and MLW?

Thanks!
