It’s 3 pm, I’m sitting in my seat and boarding is nowhere near finished. I could have been in the jetway after eating my Nathan’s. I know this is all minor but I may send a complaint Delta’s way to see if I can get some miles.

More broadly, what are the rules for airlines moving departure and boarding times earlier? What if you planned your travel to get to
a gate exactly 20 minutes before the original cut off time?
