But ultimately the same problems affect both algorithms in the same way. So the best case algorithm will be slower in the real world, but should still be faster than the other cases.
I don't think we can make that claim. There is no reason to believe the problems will affect both algorithms the same way. Some may be more fragile or failure resistant to different failure modes.
I'm also convinced that we exit the plane in the worst way possible. We basically do it row-by-row: as the people in front of them leave, people in a row get up, get their bags, start walking down the line, and this cascades up the plane. The problem is that there is very little parallelism: while people in the next row to leave are getting their bags, no one is exiting the plane. This is similar to a stall in a proc…
I was on a flight a year or two ago where, upon landing, a woman turned her phone on and received a call informing her that her brother had passed away. She was understandably quite distraught as we taxied to the gate, and the lead flight attendant even made an announcement asking everyone to please remain seated so that she could exit the plane first. Nobody listened.
IMO _how_ you treat the "cattle" (as a commenter in this thread referred) is the deciding factor. Some flight crews have a solid leader or two who can really command the respect/fear of the passengers' collective psyche. Like that strict but good teacher you may have had in middle school who ran a tight ship.
Some flight crews are meek and/or too drained give a flying f*.
I would like to see the carry-on to go away. I understand the consequences would be quite harsh at first, but I do believe the airports and airlines would eventually figure out better ways to handle luggage and we would all be better for it.
I can't find a lot of information online, but I remember an airline employee telling me that the "P90 SLA" for handling baggage at big European airports is 20 minutes. I don't think there's a lot of room for improvement, let alone a dramatic increase of the volume of checked baggage.
I would like to see some more innovation around luggage handling.

So Ryanair will take care of my 5 year old while I fly? Sounds peaceful. Last flight she spent 2 hours trying to lay down in the middle of the aisle.
Ryanair sadly don't do unaccompanied minors, but for an airline that does (and 5 seems to be the lower bound), and if flying with a partner, I've always wondered if the following would work: Parent A flies without child on Day 1; Child is given to airline by Parent B on Day 2 and retrieved on the other end by Parent A. Parent B flies without child on Day 3.

> getting on/off with my family is not optional for me If you’re getting off with your family you should just wait for everyone else to exit first anyway unless you have a connecting flight with no time margin or something. Families are super slow to deboard planes. If your kids are young, you should probably be allowed to board first before other travelers. A column by column rule wouldn’t apply to you either way.
> If you’re getting off with your family you should just wait for everyone else Uhh, no. First of all, we aren't slow, second kids have tiny bladders and third when did childless folks become such fragile babies?
What’s new is that they also just don’t care.

There's a documentary on Netflix, I think it's called "Speed" or something because it's about fast stuff, had an episode about doing Monte Carlo simulations of plane embark / disembark sequences that were optimal. They came up with optimal boarding processes but it required individual seat assignments which was a problem for kids (not to mention a ton of explaining). I forget if Southwest's semi-randomized approach w…
Southwest would have been my guess for the worst. Generally I see them using a 3seat-aisle-3seat configuration. The plane always fills up window and aisle seats from front to back, then only once people have explored the whole plane do they resort to a middle seat between two strangers. Everyone is basically incentivized to act as greedily as possible so it takes longer than it needs to.
These two things aren't connected (greed and time blocking alsie). the greedy answer is to get comfortable and settled in your bubble, fast.
I am a SW FF, most of the other people on my planes are, and we get it...we move and seat quickly to allow others in. I'm guessing far better average plane etiquette than most other US airline's FFs (though all FFs are likely above average).

Except this is not true. Quicksort is typically faster than mergesort, but worst case it can be very much slower. The worst case does not affect both algorithms the same way.

Only if all algorithms are affected the same way by the same external factors, which simply doesn't happen. It's like when a Toyota and a Freightliner crash into the same wall. They both crashed at the same speed, why is one damaged more than the other?
Maybe there is an algorithm that boards a plane faster when there are 2 handicapped people, 3 drunks, and 1 person being late. But how typical is that? And is it realistic to design the whole algorithm around that? I would argue it isn't.
Earlier quoted context omitted.
This sounds like it might be faster, and I might like it for solo business trips, but getting on/off with my family is not optional for me. Assuming most multi-passenger groups feel similarly, and assuming solo business passengers represent only ~40% of the population, the impact of such a system (which would require substantially more passenger discipline/planning) would be pretty limited.

And this is why your kid won't speak to you after age 18.
