if you go to the "flight schedules" tab on emirates.com, you can enter your city pairs and dates and it will list the flights and equipment for that day.

it will also show something like this.... F/J/Y or J/Y for each flight number.

F is first
J is business
Y is economy

meaning that will be the configuration of your AC. do not use seatguru.com for true emirates seating configurations. unfortunately it is not up to date for emirates seating.
