Middle Eastern carrier Emirates is again attempting to switch its Moscow operation to an all-Airbus A380 route, after backtracking on a previous effort.
It operates two daily flights to Moscow Domodedovo from Dubai, using the A380 and Boeing 777-300ER.
But Emirates says it will deploy A380s on both rotations from 1 October.
It had previously disclosed plans to turn the Moscow link into an all-A380 operation in 2014 after putting the double-deck type into service on the route in 2012.
But instead it reverted to using 777-300ERs on both daily flights, before reintroducing a single A380 service last year.
"Replacing the  will significantly increase capacity on the route and meet growing demand from customers," says the operator, which began serving Moscow in 2003.
Its use of 517-seat A380s on both daily flights will provide more than 1,000 extra weekly seats on the route, it adds.
