I've been keeping my eye on the Maverick GC flight at 1m LP's and much to my surprise got the "Next" button when I clicked on it. By the time I filled out my name and e-mail address it had gone.
Happened again, this time for the 300k night flight. I think I need to copy my email address so that I can just paste it in and save a second or so!
I would definitely suggest copying your email so you can paste it real quick during redemption. That is what I have done for every reward because I was having the same issue. Good luck!
Also it doesn't matter what you put in the boxes for first & last name - I just put a letter in each box, then like you said, copy & paste the email address
I was fast today, finally snared the two Red Rock breakfast or lunch buffet. Been trying for about two weeks.
