When special fares are purchased from travel agents that have contacts with EK, there is a special ticketing method called "IT" or "BT" ticketing.

IT= Inclusive Tour
BT=Bulk Ticketing

The actual fare paid is surpressed from showing up on the e-ticket and instead the letters "IT" or "BT" show in the fare boxes and fare calculation.

Tracking is done by what is known as the "tour code" and "net remittance" fields of the ticket.

The only way to know what booking classes were used is to either ask EK, or ask the travel agent who did the booking.
