What does "no seats available" mean?

Ugh, "no seats available"? Don't you just hate that? Seriously, it makes my stomach clench every. single. time. Because let's be honest, it's almost always a big fat lie, isn't it? What it really means is the airline oversold the flight, and now I'm basically playing roulette with my travel plans. Am I going to get a seat? Or am I going to be stuck at the gate, frantically refreshing the app, praying someone else misses their flight? It's like dangling a carrot in front of you, only the carrot is your vacation and the dangling is by a very frayed, very precarious thread.

I remember this one time, flying back from visiting my family, I saw those dreaded words: "no seats available." I had this sinking feeling, you know? I'd already checked my bag, said my goodbyes... what was I supposed to do? I spent the next hour practically glued to the gate agent, feeling like a total beggar. "Any updates?" "Anything at all?" Finally, five minutes before boarding, someone didn't show. Relief washed over me, but seriously, what a nightmare! I felt like I'd aged five years in that hour. Why do airlines do this to us?! It’s so incredibly stressful. I swear, they should have to give out free therapy vouchers with every "no seats available" message.
