British Airways has suspended indefinitely its frequent flyer relationship with S7 Airlines.
Members of the British Airways Executive Club can no longer earn or redeem Avios on S7 Airlines with immediate effect.
S7 Airlines has been a member of the Oneworld alliance since November 2010. This ordinarily entitles members of the BA Executive Club to reciprocal frequent flyer recognition when flying with S7 Airlines.
Before current events, S7 Airlines operated domestic flights within Russia and to Europe and Asia, principally from its hubs at Moscow Domodedovo and Novosibirsk International Airport, Tolmachevo.
BA also codeshared on S7 Airlines flights within Russia.
This move is clearly academic as it is unlikely many BA passengers will be flying either to Russia or on S7 Airlines in the medium term. Russia may well remain outside the rules based international aviation order for many years to come.
Sanctions imposed by Western governments include the cancellation of aircraft leases and the prohibition of the supply of aircraft spare parts and support services. This means that Russian airlines are unlikely to survive in their current form.
The Bermuda Civil Aviation Authority, where many Russian aircraft are registered, also suspended the airworthiness certificates of all Russian operated aircraft from Sunday 13 March.
S7 remains a member of the Oneworld alliance for now. It is inevitable that its membership may be terminated. This could be through unilateral action by Oneworld or S7 no longer complying with the terms of membership.
