Russian and Portuguese aviation authorities have agreed to add a second designated carrier from each side for the routes between the countries, ATWonline reported.

According to Russia’s Federal Air Transport Agency, approved airlines are allowed to operate up to 14X-weekly Moscow-Lisbon service and up to 7X-weekly service on other routes connecting the countries.

In June 2009, TAP Portugal launched 5X-weekly Lisbon-Moscow Domodedovo Airbus A320 service, which the airline increased or decreased frequencies depending on demand. In July 2014, the Portuguese flag carrier announced Lisbon-Saint Petersburg seasonal service.

On the Russian side, Yekaterinburg-based Ural Airlines operates 2X-weekly Moscow Domodedovo-Lisbon A320 service.

Krasnoyarsk-based KrasAir had operated Moscow-Lisbon services, but went bankrupt in 2008; Transaero Airlines went bankrupt in 2015.
