As per an agreement signed in Moscow Thursday, the two countries also decided to increase the number of flights by designated carriers to 52 per week from 46 at present.

The additional flights will be to western city Ahmedabad and northern city Amritsar, with each of them getting three more flights from Russia, a Civil Aviation Ministry spokesperson said. "A mutually beneficial agreement was reached, under which the designated airlines of the two countries will continue to be permitted to over fly the territory of the other country without restrictions," she said.

The decision comes weeks after Moscow suddenly decided late last month to bar Indian flights from flying over Russian airspace, forcing an immediate Indian reaction to ban Russian aircraft to come into the country. However, the matter was resolved promptly through political and diplomatic channels.
