First flights on AY have just credited to my BA account

[Seagull]

I’ve just returned from a trip to Singapore flying AY out on Sat 29th and back yesterday April 2nd. My outbound ones have just appeared in my BA account and as they’ve credited after April 1st have been calculated at the new rates.

All flights were in Business Flexible (D) = 50% of miles flown.
Distance calculated using GC Mapper.

LHR-HEL = 1,151 miles, which would be 575 tier points –> I’ve been credited 1,258
HEL-SIN = 5,761 miles, which would be 2,880 tier points –> I’ve ben credited 2,200

Given we don’t know how they calculate the distance the HEL-SIN is possibly close enough, but not sure why the LHR-HEL is more than double. Final oddity is that my TP total for the year is only showing as 220, not 3,458. I’ll wait and see if this fixes itself.

The total is exactly what you expected, breakdown is weird, so all fine.

You should get 6892 in total.
Even BA’s calculator gives the following:

565 TPs for LHR-HEL x 2
2881 TPs for HEL-SIN x 2

check again if AY had all 4 flights in D

I think as you flew before 31 March BA has taken the old tier points and multiplied them by 15.71 to get the TP under the new scheme. So LHR to HEL is 80 x 15.71 = 1,256 and HEL to SIN is 140 x 15.71 = 2,199.

This can’t be right cause he flew with AY, not BA. Eligible flights for conversion are BA/IB/AA

There are too many unknowns here. The OP said ‘flying AY’, which may or may not mean AY ticketed.

If applicable I think the multiplyer is 13.33 not 15.71 anyway. Certainly is for BA, haven’t researched the impact of other airlines tickets, and all also varies subject to whether the ticket was booked pre or post Dec 30th.

It’s very confusing. My lifetime tier points converted to the new total using a multiplier of 15.7143.

Which is why I suggested that and it gets very close to what has been posted. But as @AndrewT says that isn’t what the multiplier for converting old TP to nTP would be. The examples on the website suggest a multiplier of 13.35. In which case it looks like bank error in your favour. Except the TP should’ve posted to your old year.

I wonder if in fact what has happened is that they did post to the old year as 140 + 80 = 220 (which matches your old year total) and what you’ve seen posted in the new year is those figures multiplied by 15.71 to add to your lifetime total?
