Do Long Range Models Carry Less Pax?

Sun Jan 12, 2003 1:52 am

Is it so that the "ER" and "LR" models carry less passengers than their normal counterparts, whats the seating capacity of the new 744ER and the 777-200ER and LR models?

Difference between 772ER and 772LR is basically increased thrust for the 772LR.The LR also has wing-fences to improve take-off performance(a la 32X)but they will carry the same number of passengers(Boeing site shows about 5 pax less for the LR as flight lengths will be crazy so slightly bigger 1st+biz class seats.

There is no difference in passenger capacity usually, although some cargo space may be sacrificed on ER conversions to make room for extra fuel.

While there's little/no difference in available seating area on IGW, LR, and A models.... you'll usually find that airlines will choose to offer fewer seats in the extended ranged aircraft for use in longhaul.

Actually, they often times have modified fuel tanks and rerated engines. The point of having an ER designation is to maintain (or increase) payload capabilities and increase range simultaneously.

I was speaking of seat number/arrangement, not payload in totality.

To get my point across... show me 3 or more airlines that actually fly a 772ER with 300 seats on scheduled trips more than 5000mi... and I'll show you a surprised face!  Big grin

EK is the only one I can think of.

What about an SP, they were shortened. I dont know if it was for range though.

The "S.P." stood for "special performance" and the 747SPs did have significantly long range for their time... however, like most shrink models, the 747SP was too proportionately heavy to be truly economical.

So it seems like PIA's plans to replace their eight 747s with 8 777 is flawed already.
