Welcome to AFF!
If you're new to LM, you might want to start with other programs first. As someone mentioned recently, it's not for the faint of heart. The time and stress you experience trying to buy miles and/or make bookings can be enormous.
The website is an absolute nightmare and broken in so many ways. And customer support can be hit and miss.
I have been trying to buy miles with the current 145% promo for the last 2 days but the website was showing constant error messages and not completing the payment. I succeeded today on the phone. But then the CS person clearly didn't want to help me with booking the award, even though the error messages were happening on the phone as I was speaking to her.
Now I can't book the redemption I want as the website is not working again. So I'm trying to call back or I might email support:
[email protected] It's never ending problems!
The number I've called a couple of times over the last few days is +1 800 284 2622.
Good luck!
