There’s an interesting anomaly that I’ve noticed, that several readers have asked about and that’s been discussed in several forums recently. American seems to be using ‘married segment’ logic for upgrade availability sometimes and on some routes. I’m not certain that this is intentional, but it throws a monkey wrench into how we track upgrade space but also creates an opportunity for jumping the upgrade queue internationally sometimes as well.
Let me explain what married segments are, how to use the information to find upgrade space that you wouldn’t otherwise know about — and what to do to jump the upgrade queue.
