Depending on who you've booked with (ie direct with an airline or via a consoldidator such as Expedia or Travelocity) it'll either show up an individual charges (in the case of the former), or a bulked charge (in the case of the latter).

If booked direct with the airline, the charges will show up not only with the name of the airline and pax, but also routing and cabin class (in the case of the latter invariably wrong).
