Sorry, that is what the press release states.. (nashama, the link you provided is all passengers, not international passengers)
Dubai International kept its position as the world’s busiest airport for international passengers for the second year *after traffic exceeded 78 million in 2015.
Aided by 100 airlines that connect the airport to 240 destinations around the world, airport traffic increased by 10.7 per cent last year over the 70.4 million recorded in 2014.
Passenger numbers reached 7.05 million in December alone, an increase of 8.5 per cent over the 6.4 million passengers that passed through the airport in August 2014. On average, monthly traffic for the year was at 6.5 million. But since August, the monthly traffic has exceeded the 7 million mark consecutively.
