DOH 2 EH 2732 3862 4074 EH 0M 212 0 5092 0 2731

The TPM column is the one BA is using for calculating Avios (both for earning and for Avios required to redeem)

I have been playing around with some scheduling APIs that also included TPM, so as of today the Avios/tier point calculator on Speedbird Online uses TPM and there should be no more gaps between Avios calculations on Speedbird Online and ba.com. The Advanced Calculator continues to be based on actual distance (there are just too many potential city pair combinations).
