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 heartbeat extension.
