Show HN: I built tool that prevents burnouts and increases efficiency (assignix.app)

Carryons are by far the best experience for a passenger - your bag is there with you and you don’t have to arrive at the airport early, nor wait around at baggage claim. All business and frequent travelers would pay extra for this.

Meanwhile, carryons are worse for everyone else, and for the airline! They massively slow down the boarding and deboarding process while you wait for people to heft their massive suitcases up into the bins.

Fewer carryons means faster turnarounds which means more profit.

Thank you for listening to my talk.

Honestly that's pretty brilliant. But I think the airlines have some incentive to encourage travelers to carry less weight overall.

Charging for it is the incentive.

I found this article to be clearer:

The requirement to buy the extra seat beforehand makes sense because Southwest no longer has open seating and someone who bought that extra seat would need to be moved during the boarding process, but they wouldn't know what seat is open.

Step two: make the seats smaller and smaller and smaller until MOST people have to buy multiple seats. Over 150 lbs / 70 kg? Two seats, sorry, nothing we can do, that’s the rule.

Is there any regulation around minimum seat size an airline can sell? Or could all airlines keep shrinking all seats while also implementing requirements to buy more seats?

I have very broad shoulders and while my butt fits in the seat with room to spare my shoulders encroach in other seats due to Southwest’s small seats. Why should I be required to buy another seat for something I can do nothing about?

For sake of argument, why shouldn’t you?

What if an airline wanted to charge by the pound? Or by the cubic metre? “Identify how you please! We just move matter. If the matter requires oxygen, water, or 2.5 pretzel sticks, we will gladly sell that too! Looking for extra savings this summer? Try our new sweat lounge! Your precious bodily fluids are fungible, so sweat them out now and reconstitute when you arrive!”

For what it’s worth, I’m very very strongly in support of socializing things like this and would prefer to live in a community that is of the leave a penny, take a penny mindset.

I support this, but I also think airlines have a responsibility to stop shrinking seats. It shouldn’t be a contest to see how many more seats can be fit onto the airplane. Give us normal sized, comfortable seats as the standard.

I agree. I’m 6’4”, 255 lbs - framewise, I am a gorilla. I can’t even get an exit row seat as my son isn’t old enough to sit there.

It’s ridiculous that seating is so tight that there is no way for me to be comfortable for any significant flight and it’s miserable for anyone other than a child around me.

Whenever I can, I fly in a premium cabin. But if that’s not an option, I’d rather drive 7-10 hours than fly economy.

Same boat here. I'm 6'10", 260, and athletic. I'm very acutely aware of the shrinking space available on aircraft, and there's precious little that I can do about it. I typically just get an aisle seat and raise the armrest after takeoff (and then spend the whole flight dodging people going to the bathroom and refreshment carts, but it's better than nothing).

There is a problem with heavily obese people taking up significantly more horizontal space than is actually fair, but it's absolutely compounded by the airlines shrinking the per-passenger space to the size of the average passenger.

Ok but guys, 6 4 and 6 10 is incredibly tall. Surely you see that's edge case AF?

hattmall · 58m ago

At 6'10 I can't imagine much anything is comfortable.

Oh thank god. i do not yet know a single person who did not favour such policy after at least once being impacted by an airline not having it.
