2-4-1 redemption upgrade, not charged?

It needs reticketing which is a manual process with often long delays. Payment will be taken when this happens.

There’s a known issue where if they don’t process payment in a reasonably short period the pre authorisation drops off & they have to call you to take payment details again. There are reliable reports of people who have missed/ignored these calls & ended up travelling in the original cabin (or not at all).

BA’s IT is often flaky but it’s very good at matching up reservations (what you currently have) with payments. This isn’t a gamble I’d take so if you get to 1 week before departure & the payment hasn’t been taken you need to call up & cough up or you’ll be sitting in WTP.

How would this work with avios points? As I’ve just purchased 20k points to make up the needed points for the upgrade – account still hasn’t had the avios points deducted. If I were to request an avios purchase refund (14 day policy) would my avios balance then go into negative? Very confusing what happens next.

May just leave well alone!
