Any well-written article should anticipate, ask, and answer the obvious questions. For example: Why not use alphanumeric characters? And if the answer isn't known by the sources the writer quotes, the writer should say so.

Airlines are running out of 4-digit flight numbers

Also, connections. If it's a connecting flight, and the incoming flight is running late, then the airline "sorts you out". Basically they know sboit your connection and make a plan. I've been on a plane out of Heathrow that waited for a 30-min late incoming flight. I've also been on a late flight where my connection has been rebooked for me because we arrived late. If you book "2 tickets" you're basically a no-show t…
You don't need to be on a codeshare for that to work though, it just needs to be on the same itinerary - the flight numbers can be on different airlines and still on the same itinerary.

#113I love that so many people here think they can think about the problem for 10 seconds and come up with a solution that hasn't already been considered a thousand times and discarded.

I did that once - book connecting flights on two different tickets - and although I ended up actually making the connection (despite the first flight running 2-3 hours late), the experience was so nerve-racking I swore I’d never do that again. It helped that the flight I was connecting to ended up running late too. The reason I did it was it was a personal side-trip (to see family) on an international work trip, and…
How does that work, given that the cost of the personal portion isn't independent of the rest of the booking?
I was just looking at a flight plan on kiwi.com that they could book for $900, with the individual legs costing $250, $350, and $500 if booked through the carriers.

#115Give the flights a 128 bit number, so we can give each grain of sand on Earth its own flight number.
I'm pretty sure they want to keep flight numbers short because that's how passengers identify their flight. As a passenger, you wouldn't want to be reading signs with 40 digit flight numbers. Attention passengers, flight 3467548742468759027225995322800483168368 to Dallas is now boarding.
That wouldn't describe any passenger I've ever known, including myself. We identify our flight by destination and departure time. Airport boards are conveniently sorted by departure time.
In case of a tie, I'd fall back to airline, also indicated separately on the board, but a tie over destination and departure time has never happened.
Re: Airlines are running out of 4-digit flight numbers
#116Clearly the successor solution is to use eight groups of four hexadecimal digits each, separated by colons. Then each individual seat and peanut could be addressed to it's final destination. More seriously the solution suggested of giving the 3 companies other unused prefixes like D* U* and A* to use with their codeshares and non rev flights to start seems the easiest.
Done forget to have a secondary identifier to further divide the seat. I recommend using a short to represent the 65536 possible slices a seat can split. Then on the ticket, there would be an extension section that tells you the alias of the person that is about to board. We can call it SNI or Sitter Name Indicator. Another section could be an indicator if the rider is alive when boarding. We can call the extension a…

Very obviously: do not display the hexadecimal code to end users.

The amount of travel industry software is huge, and a mix of ancient and new. Makes sense, but would take years.
Easy, add a leading 0... Oh wait they probably store them as integers, but then it wouldn't matter how many digits... Oh wait some places it's fixed length strings
Mentally if the number has significance for sort order etc, you can think they are like decimals they would be 1234.0 and 1234.5, when not set in older systems it can be ignored i.e. 1234.0 is same as 1234.
