This is not really a problem. Unless regular flight operation is interrupted on your way, e.g. due to bad weather and many flights are cancelled, it is on most routes not difficult to get a ticket on very short notice. Business travellers are doing this all the time.
Most search engines and airline websites allow you to book tickets until shortly before departure. If you arrive tonight at 2:30am at Seattle-Tacoma and want to go to Manchester as soon as possible, the soonest arrival in MAN would be with a flight 8:30am with transfer in Atlanta, arriving in Manchester 7:00am next day. A much cheaper alternative would be a departure 6:55 with transfers in Boston and Dublin, arriving in Manchester 7:40am. These flights will still be available for booking tonight at 2:30am and you can find them on any arbitrary flight search engine.
If you don’t want to bother finding a flight yourself on the internet and you have a certain idea which airline might have a suitable flight, most airlines have a 24h ticket hotline, which you can call to order a ticket.
What I would do is check redemption availability on each airline that flies the route I need to be on. e.g. I checked BA and there is redemption availability on the 18:20 today from SEA-LHR and then on to MAN tomorrow. The cost of this is 16250 avios one way and £140, or 5700 avios + £220.
What happens if you don’t have any airline miles? You can buy them. 6000 avios costs £111.
Then I’d compare this cost with the cheapest flight I could find on skyscanner (returns are often cheaper than one-way). In the BA case it’s several thousand $ for the same flight.
Couldn’t be easier,
To determine which plane leaves next
click to expedia on your phone. you’ll instantly have the answer.
alternately, go to the web site of the airport. They always show live departures about to happen. portseattle.org/Sea-Tac/Flights-Airlines/
alternately, literally just in the google search bar, type the phrase “flight Paris to Tokyo” and just select “today” on the popup which appears. Google now has this totally built-in.
You will now know which airline you are going on.
Then to purchase the ticket
or if you prefer to pay in person
Note that these days, many folks don’t even realize there’s a “ticket sales desk”, for each airline, at airports! Because it’s little used these days.
Note that you mention:
Kayak or Expedia .. don’t work for ultra short-notice travel
This is wrong. I buy on the way to the airport all the time.
jump-seat ticket
They don’t have those anymore.
cargo airline made accommodations for emergency passenger travel.
not for 40 years now.
If you are trying to get stand-by seats or similar – very simply phone the airline. Again, use expedia on your phone to determine “who’s leaving next”.
