Emirates will roster an A380 to Copenhagen from December 1.
The service will be the first time an airline has operated the superjumbo in a two-class configuration and will seat 615 passengers, with 58 fully-flat seats in business and 557 seats in economy.
It will also be the Gulf carrier's first A380 service to Scandinavia.
Outbound flight EK151 will depart Dubai at 0820 and arrive in Copenhagen at 1220, while return flight EK152 will leave Copenhagen at 1420 and land in Dubai at 2335.
Emirates CEO Tim Clark said: "After launching the route with an A330, we witnessed growing demand for flights to and from Copenhagen, forcing us to deploy the larger 777 after only six months.
"Today, based on strong load factors, we are happy to further up-gauge the route to our iconic double-decker, the A380."
Thomas Woldbye, Copenhagen Airports' CEO, added: "We made significant investments to expand Copenhagen airport and upgrade its facilities in order to make it A380-compatible. Copenhagen will be the first in Scandinavia to offer a scheduled A380 service."
In February, fellow Gulf airline Qatar Airways upped its Copenhagen service from daily to 11 weekly (see news, November 2014). All four extra services are operated by a B787-8 Dreamliner.
