752ER
 

Is there such a thing as a 757-200ER as opposed to the regular 752? I've never heard of this before, but the below article claims that there is. What I'd like to know, is does CO have both types, are all of their 757s the -ER version, etc. Thanks

I've never heard of an ER version of a 757.

exactly, and also Boeing's website doesnt list it as such. So is it just engine choice and over-water equipment which qualifies CO's 752s for transoceanic flights as opposed to, say, DL's? Also, I remember BA and LY flying 752s to JFK for a very short time. Also TW using them to HNL, which is 4100mi territory.

It all depends on whether or not the aircraft or airline is ETOPS (Extended Twin Engine Operations) certified.

It would take too long to explain here the ins and outs of ETOPS, but Continental is ETOPS certified, and the 757s they operate are ETOPS certified.

Each and every jet in the fleet needs to be ETOPS certified, not just the one aircraft for each.....

HP has I think 2 or 3 ETOPS certified 757's but not all of them can go over to say HNL if they wanted to.

I understand quite extensively the ins/outs of ETOPS, what I'm wondering is if a 752 was built with modified fuel tanks, aerodynamics, et al which Boeing usually installs on an offical -ER model (in the fashion of the 777 and 767s)... or is this article just anecdotal.

Correct, each specific aircraft needs to be ETOPS certified. Thus, some CO 757's are ETOPS certified, but some aren't. So the one's that aren't wouldn't be able to sub in for EWR-LIS, but the ones that are of course could fly EWR-FLL.

Most airlines designate their 757 ETOPS as 752ER in order to distinguish them from non-ETOPS birds.

Yeah, seems to be a logical explanation. What [operational] differences are there between the ETOPS and domestic-only 752s? Engine choice? Extra fuel tanks? "better" transponders? Over-water equipment? etc.
