I see that LH have retired the Meilenrechner (https://meilenrechner.de) for calculating miles earning and put a new calculator in the Miles and More app. The new calculator has to gather a lot of information to accurately work out earning.

As one app store reviewer put it...



App store review of Miles and More app

Having used it a couple of times, I'm seeing some inconsistences. Is anyone else noticing these?

Can't calculate miles on codeshares correctly
LH9729 BKK-BNE booked on an LH (220) ticket in V class. Actually operated as TG474, and LH/V cross books in to TG/K.
The app shows miles earning as 1,130 status miles - it's used the LH V class, applied that to TG, and decided it's 25% earning.
The correct calculation should be 2,260 - the LH V should be mapped to TG K, which is 50% earning.

Odd calculations for European short-haul flights
LX317 LHR-ZRH booked on an LH (220) ticket in K class. Senator status (so 25% miles bonus)
The app shows miles earning of 245 status miles.
The correct calculation should be about 156 status miles (125 for K + 25% bonus of 31 miles)
If I look at other Euro short-haul destinations (e.g. LHR-GVA, 241 miles - LHR-FRA, 223 miles) it looks like it's using the fixed miles as the base, but then using 25% of the *flown* miles for the bonus? Is this... new?

As I'm going to squeak SEN requal this year, not having trust in the calculator to be accurate is a bit unnerving.
