Sure, but everyone agrees that first class is full of perks. “People taller than 6’1 can sit here without being in pain” shouldn’t be a multi-hundred dollar up charge.

I agree with all that. The food still isn't great. And the seat still isn't great for a red-eye relative to business. I wouldn't generally work on a plane anyway. I've been in PE--don't remember the circumstances--but as I recall didn't think it was anything special for the cost.

Premium doesn't have to mean "elite," it might also refer to a risk premium or any situation where a buyer has to pay extra. ;)

Eh, they already had economy plus. Premium economy is basically traditional domestic business class on widebody international flights that have lie-flat business (Polaris) seating as well. Honestly, putting it in the economy bucket in contrast to Polaris seems pretty honest in the scheme of things.

When I used to have carry-ons, boarding early ensured that I got room in the overhead bins to place the bag. I now use under-seater bags only and pack light so I no longer care when I get to my seat.

Recently I had received a mini packet of crisps that had four in it.

Four

How is that even worth the packaging cost

This isn't totally dead. I missed a flight last year and got bumped to a flight the next morning on some weird ticket class where I didn't get a seat assignment until the gate. The gate agent was able to give me a bulkhead seat with extra legroom at no cost. And this was with United, not some airline with a shining reputation for customer service.

So you can roll the dice and try to get a premium seat at the gate, but that's not a risk I'm usually willing to take.

Most airlines require very wide people to buy an extra seat. The requirement is that they have to be able to lower the armrest.

There's rules for passengers and airlines... but enforcement is limited, because who wants to slow down boarding by checking.

And compliance is hard for passengers, because you have to call in to book the special case, and who wants to call in?

But theoretically, a passenger that will encroach on an adjacent seat can pay for the extra seat (I don't know if they need to also pay for seat assignment to get two seats next to each other), and then if the flight doesn't actually sell out, the extra seat fee is refundable. But when you actually board, people will see the 'empty' seat and try to sit in it, even though you paid for it. Etc.
