Gulf Air re-qualification
 

Does anyone know how this works? Is it based on the 12 months preceding the expiry date?

yes it does. Once you reach your status level you have 12 months from that date to accrue the number of tier points you need for re qualification. I was gold and dropped down to silver because original qualification for gold is 2500, then you need 1750 to keep it at your anniversary month in a year from first achieving it. If you have 1750 you keep it another year, if not you are silver.

I think the silver is 1000 for initial qualification and 750 to keep it, but I'm not going to waste my time looking it up, I'm sure you will.)

Gold doesn't really get you much other than a guest into the lounge, 50% bonus on RDM instead of 25%, and higher op up %. Not worth the loyalty. Silver will do me just fine.
