cant sneeze at that.... I guess the key is to get off the plane asap and be the first on line in customs and immigration. avoiding checking luggage
pray your flight does not land at the time time as a packed wide-body

I would be extremely surprised if (in the USA) there was any private service that makes going thru government (TSA, immigration, customs, etc) any easier - unlike the closer relationships for Flag carriers in other countries....

I think GE helps - but I never found it that useful recently (there was a travel app - but I dont recall the name that helped zip thru vs the blue long forms that you need to fill out)

having a US passport helps a lot......
