If a manufacturer produces a family of Jets such as the 737G, A318/319/320/321, 772/772ER/773, do they usually share the same wingspan/wingarea and engines?
I've heard in some of the other forums that HP will not purchase the A321 because it doesn't have the peformance necessary to operate in hot/high conditions at PHX and LAS. The reasoning I was given was that the A321 was simply a longer fuselage with the same wingspan and engine size of its smaller family jets. Is this true? Is this common? Does a larger variation of a jet suffer from lack of power and performance if they don't upgrade the engine size and wingspan? just curious?

Yes and no...
The A32X series shares the same wing along with the A330 series
They share the same wing upto a point where they change the design too much and a wing change is required.
And your last few questions... Yes
If you increase the weight then to acheive the same performance as a smaller jet you have to increase the power. If you dont, you lose in performance. For alot of airlines this loss is negligible. However in HP's case the loss was a major factor
