I guess it's too far back to pull up the flight plan. I'd like to see the reason.

In the last year or so I've seen some strange weight restrictions. The 321 sometimes runs into balance issues with lighter loads, and the load system doesn't allow a restriction for balance(didn't, I haven't seen it in a while), so the load planner would put a weight restriction on it instead. I've had to intervene to let folks know we really didn't have an issue. I recently had a restriction eastbound because the dispatcher was planning way too much fuel.

We rarely have a weight issue on the 321 transcon from CLT. The 320 is the one we have issues with. Sorry you had a problem.

But back to your initial point-the 321 is no 757. It does a lot of what the 757 can do, and much cheaper, but there are compromises. I say that it has a great smooth ride detector, it always seems to be 500' above recommended max alt!
