I'm 2 for 2 so far, once at DTW and once at LGA. I forgot I had a bottle of water in my carry on at LGA but they weren't too upset about it, just took it and sent it on my way.

My Skymiles profile name and GOES name are the same, but I don't have my middle name in the "Secure Flight Data" section. I was going to add it in but it hasn't seemed to make a difference for me.
