I've been FO for about 8 months, but on my recent flights (last 3 weeks or so) I've been getting Sky Priority boarding passes (Zone 1) and messages to take advantage of my Sky Priority benefits when I OLCI. I am not particularly close to GM (16K left), though I have flights booked to get me there. I thought maybe it was because I was able to clear upgrades, but on my current delayed flight, I have no chance on either segment. Also, I don't believe they tagged my checked bag as Sky Priority even though my boarding pass shows it. Any insight into this? I'm curious about using Priority Check-in and Security since my BP says both Silver and Sky Priority. So far, the normal lines have been short enough that I haven't had anything to gain by trying it out, but I might do it next time just out of curiosity. I'm wondering if maybe I should just keep my mouth shut and act important.
