Jag rättar mig själv, för det skiljer numera beroende på vad det är för miles, dvs. hur man förtjänat dem
Miles från bilhyra förlänger livslängden på miles intjänade på bilhyra, men inte på de man tjänat på att flyga.
How long are my Miles valid?
All your Miles are valid for life as long as you take an eligible flight on Air France, KLM, Aircalin, Kenya Airways, TAROM or other SkyTeam partners at least once every 2 years, or if you're an Elite or Elite Plus member, or if you make a purchase with an eligible co-branded credit card at least once every 2 years. These
"Overall extending activities" extend the validity of all Miles 2 years from the date of the activity.
You can also extend the validity of Miles earned with all other partners (airline partners not mentioned above, car rental partners, hotel partners, and experience partners) for 2 years by earning Miles with any of these other partners. These
"Partial extending activities" with other partners will extend the validity of Miles earned with any of these other partners by 2 years from the date of the activity. Please note, "Partial extending activities" do not extend the validity of Miles earned from "Overall extending activities".
