Take for instance my latest inbound package. It's gone from a California origination to Hapeville, Georgia, to Atlanta, to Louisville,Kentucky, before showing back up in Doraville, Georgia just outside of Atlanta for delivery today.
This was first advertised by UPS to have arrived on my porch yesterday, as a "second day air" delivery. But after it arrived in Louisville, UPS added another day, but still touts my Christmas Eve delivery date as "on time." There's actually a step prior to what's shown in the chart. The package entered the UPS system Monday evening, California time.
Wish I knew if the wayward routing was by accident or design.
