Tracked/Signed For Airmail to the USA - which is best to use?

[sidthelamp]

Packages that get stuck in New York, LA or San Francisco are at the facilities that do customs clearance. For most mail, this takes a few days before it gets back on its way to the customer. It is the same for packages to many other nations. Some private shipping services (FedEx, UPS, DHL) do their own customs clearance on express parcels, if the customer needs get through customs quickly - though at a fairly steep cost.

Packages from the EU have been going through customs in the UK, which was fairly efficient. I haven't heard whether Brexit will change how mail to the EU is inspected and sorted. Anyone know?
