Just wanted to check how many miles a certain trip would earn when I was advised that this was no longer supported and I should download the M&M app, which I did. When logging in I noticed that it’s mandatory to submit an awful lot of details (flightnumbers, paid fare, taxes etc. etc.) yet unknown to me as I haven’t booked yet since choosing an airline and booking the flight depends partly on how much mileage I should earn.

Trip in question should be ARN-AKL v.v. on SQ in discounted business class.
Does anyone have an idea of how many miles this will earn me?
Thanks in advance....
