Alitalia award mile expiry
I'm looking at signing up to a SkyTeam airline to get miles for Aeromexico flights I have coming up this year. FlyingBlue is one option, as is the Alitalia programme. I can see a downside of Flying Blue is that you have to fly one paid fare every 20 months to ensure the miles don't expire. Are there similar limitations for Alitalia and/or anything else to bear in mind? Thanks.
