I admit, I'm happy to hear others haven't gotten this e-mail. I'm pretty sure United kept their old e-mail system, and I'm pretty sure it didn't work consistently across all accounts. My friend and I always had the exact same checkboxes on the opt-in options at united.com, but she got tons of e-mails, I got about 1 in every 7. My itineraries and everything worked, but announcements, general communications, special offers, I received about 1 in every 7 that she did. I tried everything, checking, unchecking, etc. Finally, I changed my e-mail address and I started to get almost all of them, but usually many days later than my friend.
I still have not received this particular e-mail. I probably don't expect to. My account still isn't 100% e-mail functional.
I am so, so glad I don't fly this airline anymore. At least, not for the rest of this year. I continue to hang out here and see how things are going, but obviously things aren't going well. My friends are reporting travel horror stories. I'm glad I have options, I know not everyone does. I feel for y'all.
