Regarding the "Z" fare class:

I was told by an international agent that the "Z" bucket reflects seats available as upgrades when you purchase a full "Y" fare. I am watching an IAH-NRT flight in November that is the key part of an eight-segment international itinerary that I am willing to pay $300 to upgrade on (each way).

The flight went from Z0 to Z4 yesterday, so I called, but was told what the "Z" meant (see above). I was hopeful because other flights that WERE available to for me to upgrade my "B" fare on had shown Z4...I could'nt take them, however.

Also, the "4" in Z4 has no relation to FC availability...there are >20 FC seats available on that flight. It likely reflects the number of seats that the CO capacity-control gurus decided to release.

Edit:

Now that I think about it, my discussion pertains to CO; other airlines may have different codes or codes that have a different meaning.

Edit2: This probably belongs in the "DUH" thread because I thought that I was in the "Continental" forum.
