This has probably been discussed before but I cannot find the answer.

I booked 2 stays, at an ibis for about £100 and at an ibis Styles for about £45. I redeemed most of these costs with Points and spent only about £8 and £11, respectively. The list of reservations in Manage Bookings says these two will not earn Points.

So that got me thinking, what is the minimum threshold for money paid to earn Points? Accor will set it on Euros. Of course, these would earn very little Points but just curious to know the cut-off level.
