Air Canada is offering status matches to British Midland elite members between June 15 and July 15, 2012. British Midland Gold matches to Air Canada Elite, and British Midland Silver matches to Air Canada Prestige. It’s worth noting that the status will only be valid through February 28, 2013.
Best I can tell as an Air Canad Elite you would earn 25+ eUpgrade vouchers (though I’m not sure you get those if you match) which are good for several upgrades (you can calculate how many eUpgrade vouchers are needed for any flight combination here). Does anyone know if Air Canada usually grants those that get status matches eUpgrades?
Either way, Air Canada Elite status comes with Star Alliance Gold, which gets you into Star Alliance lounges whenever you’re flying a Star Alliance carrier, even if it’s just domestic.
