The US Postal Service will no longer ship packages by air and then by ground

The US Postal Service is ending its International Surface Air Lift (ISAL) service. This means packages sent internationally will no longer travel part of the way by air and then switch to ground transport.

This change simplifies international shipping options for the US Postal Service. It removes a middle-tier service that was slower than airmail but faster than sea mail. Shippers will now choose between faster, more expensive air transport or slower, cheaper sea transport.
