Does your confirmed ticket show your changes as being marked OK or NN or HK? This means that your ticket is valid for travel whether or not we (the airline) is holding a reservation for you. You are confirmed and must be treated as a passenger needing a seat, subject to a DBC/IBC being issued if you are not seated on the flight.

If your ticket shows the AF segment as being LL or WL, this means that you are not confirmed on the AF segment and will not be considered a passenger until the waitlist clears and the segment indicator will then change to OK, NN, or HK.
