Qatar Airways has announced plans to drop Qmiles and adopt Avios. The change will take place in late March (rumored to be the 22nd). Existing Qmile balances will convert to Avios at a 1:1 rate. Apart from that we don’t know how the specifics will work, but that is expected to be announced in the coming weeks. Avios is currently used by British Airways Executive Club, AerClub, Iberia Plus and Vueling Club.
