For those who don't know the detail (or don't read the BA board here), progression through the BA "ranks" is a real challenge, especially where corporately you do everything in Economy. Each year those Tier Points, which need to get to 300 for Bronze and 600 for Silver, get reset back to zero. And my return trip to Dublin scored ... 5 points for the outward, and 10 return (different fare class, still in the back). I'm going to Glasgow tomorrow, that will be 5 each way. And my anniversary date for points reset is 8 May. Phew, just made it !
