Eastern Memorabilia
| Space Available Ticket Folder |
 |
| Familiar to all who did any pass-riding, this space available ticket folder lists all the classes of pass priority, from the coveted C1-S and C1-V (Vacation) to the lowly C4-OA (Other Airline). The best pass, of course, was the C1-R (Reserved Seat), which was the equivalent of a paid seat. |
