All I can say to anyone who has the unfortunate luck to have an incoming international parcel go through the Queens customs portal, "Good Luck"! I have had 3 so far go astray and missing, to NEVER arrive. One explanation I received was that there is soooo much mail and parcels there that it takes 4 times as long to sort through them. Some go through in one shot, others can take weeks just to leave the facility. I received a parcel from Bulgaria in a little less than 2 weeks. Another item from Italy landed in the Queens facility and never surfaced, yet.
The incoming terminal at JFK is a notorious black hole for registered and insured packages from Europe. Some postal employee has put together a fairly nice collection.
Not hobby related, but my office has a registered package that was sent from a government office in Alberta in February and has repeatedly bounced between points in Canada. The closest it came was Toronto before heading back west.
