I recently booked American Airlines award flights from Dallas to Albuquerque with British Airways Avios points. I booked it pretty fast and let my British Airways loyalty number auto-populate in the spot for “Membership Number.”

So easy to let this slide
It’s a “blink and you’ll miss it” type thing and easy to overlook.
But, if you have elite status on American Airlines, or certain AAdvantage credit cards with Barclaycard or Citi, you’ll want to change it.
