I'm sure they won't lose sleep over it. I'm sure there are numerous incidents of flight prices moving in a cheaper direction that they are affected by. If they cared to look.

My query was more about booking Club Europe instead of Euro Traveller. I see now it must of been a pricing anomaly that allowed this return mixed fare to be booked instead of a pure Y return.

As for me, the flight is ticketed and I get a nice 50 tier points round trip instead of 20.

Regardless thanks for your efforts.
