Flew with IB when they practically gave away 90K avios. I took those nearly freebies, redeemed one TATL business roundtrip (JFK-MAD-JFK), and an AA short haul domestic roundtrip - real good bang for the buck. I even flew as many of those throwaway flights (part of the convoluted requirement to get the 90K) as I could.
Miles were worth a lot more then, and it wasn't even long ago.
Anyway, hope we have some real IB inventory soon.
