I'm looking at some transcon flights within 2-3 weeks and noticed how, as usual, A9 D7 F0.

I have no problems using mileage for an upgrade (My miles are worthless everywhere else!). Since they usually don't release seats until a week out (Generally hitting the Plat's EUA window), which upgrade would have priority if I'm put on a waitlist?

Gold/Silver elites upgrading with miles...or a platinum that gets upgrade with EUA?

Thanks!
