I can't believe all you Plats. You should be encouraging as many people as possible to remain Gold.
Not only are not being pushed and shoved by unruly Plats when we board before you are even called, but it is sooo much easier to keep track of the 25% bonus miles you get versus the complicated double miles.
By all means - stay Gold - and leave the upgrades to the horrible meals in FC to the rest of us.
