Oneworld member S7 Airlines has decided to end its Moscow-Madrid service after eight years of operating on the route.
The Russian carrier will stop its weekly flights to the Spanish capital's Barajas airport from main hub Domodedovo on 24 June.
S7 says passengers holding reservations for subsequent dates will be offered a full refund or bookings on flights by its codeshare partner Iberia, which flies daily between Domodedovo and Barajas.
FlightGlobal schedules data shows that Aeroflot also operates a Moscow-Madrid service, from the Russian capital's Sheremetyevo airport.
S7 has been serving Madrid from Moscow with varying frequencies since 2009. It retains rights to serve a handful of Spanish destinations, including Alicante, Barcelona, Ibiza, Palma de Mallorca and Valencia.
