Does Jet allow stand by on earlier flights? Here is what I am trying to do. The flight I want is sold out in economy and wide open in Business. Jet won't move my ticket to this flight as the base fare of my upgraded ticket is not available as Economy is sold out. Even though the business seats are available that day. Apparently you need to move the Economy ticket first and then request an upgrade.

What's Jet's policy on this? If I turn up at the at airport one day before then will they let me fly in Business even though my upgraded ticket is for another day? Will I have to pay the fare differance? How does that work for a sold out flight? I am currently in K.

This is for a International flight.
