I have a question for which I search yielded this thread as best match...

Regardless of when a OW partner flight's actually posts to your account, does the 'transaction date' relate to the date the flight was actually taken in its own time zone? My membership year ends on 8 April, meaning that, in a perfect world, at midnight Zulu time on the night 8/9 April my TPs get reset to 0. I have an upcoming domestic AA flight that leaves MIA after 1900 local time (ie past midnight in London) on 8 April.

When this eventually posts to my account, does it post to 8 or 9 April. I think 8, followed by a 'balance readjustment' but interested in your views.
