833-861-7710 was the first number I called when my Mileage Plan account randomly locked me out one morning. I panicked because I had an upcoming flight and all my reservations were tied to that login. The rep immediately verified my identity, asked a few security questions, and reset the account while I was still on the call. They also walked me through setting up stronger authentication because they suspected unusual login attempts. What surprised me most was how fast everything was handled—no long hold times, no transferring between departments. Within ten minutes, I had access again and could see all my miles and bookings. If your account ever gets hacked or locked, calling that number is the quickest way to get a real human to fix it right away.
