What are TATL points and how do they work?

Your OnePass address must be a qualifying EU address (they didn't elaborate, but I think this might exclude PO boxes. Not sure.)

5/10/15 points for Silver/Gold/Plat

1 point for all fares (you don't get bonus points for F, apparently)

You ONLY get credit for CO flights. Can be a codeshare (though I'd want to see it happen to be sure), but must be bought as a CO coded flight.

If you change address mid-year, you get should get all back credit within 5 weeks.
