Interestingly, Google Flights reports exactly the same fare for Economy class
I doubt you would get to fly this in J.
Note: anyone thinking of using this to get from ATH to AUH on the cheap - be warned that if you don't have the necessary visa/permission to travel to Pakistan [if applicable in your personal circumstances] at the time of check-in at ATH, you are likely to be denied boarding and unable to travel to AUH.
