Or the gate agent who looks at your pass travel date, and states that you are “junior” to the other pilots he’s already sent down so you aren’t getting on. When that pass travel date can be COEX or not accurate because of the SLI. I had this happen just a few weeks ago and the other pilot said “I saw you listed and told the agent you might be senior to me despite my pass travel date”.

Turns out I was senior, but they had a couple extra seats in the back anyway so it was moot.
