I am really confused now on what the C count in EF means? I always thought it meant the number of seats available for a Business Class upgrade (miles or SWU). If I pay cash for it, I didn't think of that as an upgrade but rather a ticket price increase. I have read posts by many stating that they saw C count of 1 on EF and called the airline to claim and confirm the upgrade.
What is the meaning of the C count, or for that matter the A count for First?
