Delta Air Lines said Friday that it is suspending ties with Russian carrier Aeroflot because of Russia's invasion of Ukraine.

SkyTeam has Delta and Aeroflot as members. Customers can book seats on each other's flights through their partnership.

Atlanta-based Delta said in a statement that they have removed their code from Aeroflot. Customers affected by these changes will be accommodated.

Delta does not fly to Russia.

SkyTeam didn't say if Aeroflot would be removed from the alliance.

Codeshare agreements allow airlines to sell seats on flights to destinations that they don't serve. Carriers often use these agreements to get more international reach.
