UPS Air Services
UPS has changed the rate structure for it’s air services. The rates for UPS Next Day and 2nd Day Air now reflect a distance-based approach. This means that if you primarily ship within our region on the country--costs should be less than previous rates. This applies to letters/packages sent via UPS "ON CALL" service or through the Central Mailroom (it does not apply to UPS letter centers).
