BA: Which day is the last day of membership year?

[dahokolomoki]

My tier point collection year ends 8th Jun 2024, as shown in the app.

Does this mean that if I fly a BA flight on the 8th Jun (also arriving 8th June local time, but will be 9th June UK time). Does that count towards my current tier point year, or the new year?

8th of the month is the last day of collection year

Fligths get posted and counted based on the local scheduled time and date of departure.

Thanks for the answer!
