I have a large glass picture frame that is boxed at 30" x 30" x 2.5" and contemplating as to how to bring it back from HKG to US. i'm looking at handcarrying. currently, i'm routed on a PMCO 772 in biz and then a Q300 from EWR -> IAD.

I've been able to find a thread with similar thoughts here:

from what I've been able to glean so far, i'm looking at the following questions:
1) Can the item make it through security - at HKG, or at EWR?
2) Can the item be stored on a 772 / Q300?

with the current itin, if i can a) get it through security at HKG, and b) get this loaded into the cabin on the 772, i could theoretically just dump the UX segment at EWR and rent a car or train it back down to WAS. another thought would be to try to switch routings (+ potentially lose an UG on the TPAC seg) and try 772/747 + domestic mainline. either way, i'm looking at reclearing with the item with US TSA and then dealing with another cabin crew.
