What are we flying over?
Sorry, I was absent that day in flight attendant school where they taught us how to identify every American city by its lights from six miles up.
Can I change seats?
Once we're done boarding, if a seat is open, sure, go to town. If you piss off the dude with the window seat who thought he had his own row, that's on you. That said, the key phrase here is "once we're done boarding." You're just inciting chaos until then.
Can I hang out back here?
In reference to the galley where we sit for those precious few moments between beverage service and cleaning up the cabin. Believe it or not, I'd prefer not to spend my tiny bit of downtime sharing 8sqft with you while you explain your scintillating job in commercial real estate. I'll be sure to return the favor and come hang out in your office when I'm bored.
Can't I just sit in one of those empty first-class seats?
No, Miss Benes, you may not. The people up there don't just buy those seats only because they want legroom and free domestic wine. And there's a very real chance that all the profit the airline will make on this flight will come down to a couple of first-class tickets. Giving them away willy-nilly wouldn't exactly thrill my bosses.
