I only discovered Badges in February which is too bad because I would probably be in the top 50 by now! Been flying them since 2002. However, I've had numerous issues too with Badges not posting on time or having to be manually posted by JetBlue. My biggest issues have been with Hilton.

However, I have been waiting for my AmEx Badge since July. I either get that the system is down and I should check back again in a few days or that they have submitted for it. I am beyond frustrated at having to keep following up with this.

As for Mexico City, I noticed with Grenada that the Badge didn't appear in the system until right when they started flying there. It may have even been after the fact. They also should have an inaugural badge for being one of the first to fly there.
