Deciphering High-Speed Train Seat Labels: The Story Behind ABCDF
The origins of the high-speed train seat arrangement, denoted by the letters ABCDF, can be traced back to the early days of air travel. In the past, single-aisle aircraft typically had six seats per row, labeled A through F. The seats were arranged in a specific pattern, with A and F being the window seats, B and E in the middle, and C and D nearest the aisle. This seating configuration became an international standard, with each letter corresponding to a specific location within the row.
