Why are BA tier points not being given on fully flexible American Airlines tickets?

Two readers have been in touch this week to point out something strange with the American Airlines earning table when you credit your flights to British Airways Executive Club.

Here is an example taken from ba.com from the London to New York route, although the same applies to other routes too:

As you can, the screenshot shows zero tier points earned if you have a fully flexible Business Class or First Class ticket.

When I was first shown this, I assumed it was an error. (Yes, I know, we all thought BA’s IT was infallible.)

However, the second reader had actually taken a flight in fully flexible Business Class, and sent me a screenshot from his BAEC account:

In this case, he had flown on Finnair but it was booked under the American Airlines flight code.

As you can clearly see, he was in ‘D’ class (fully flexible Business Class) which earned Avios but no tier points.

This is totally bizarre and makes no sense. I am still convinced that it is a BA IT error, but potentially a deeper problem than just a display error in the BA tier point calculator.

This issue will hopefully get fixed and reverse itself automatically, but for now you should keen an eye on your BA account if flying on fully flexible American Airlines tickets.
