Due to language or alphabet restrictions this may not be the nominal edition
distributed in the carrier's home country. 1B.

Designed for regional
distribution elsewhere than the carriers home country. In quick reference
editions a regional system often only includes extra-regional services
on a direct or nonstop basis. Often a regional is differentiated from Class
1A on only small points. It's value relation to class 1A will vary by carrier.

CLASS 2 - REGIONAL TIMETABLE

collection.

Joint Regional.
Combined services timetable
of two or more carriers. 2C schedules are filed under issuing or dominant
airline.

City Quick Reference
timetables are distinct from Regional or Local issues because of
their distinct lateral commonality. Like 2A or 3A issues, this series is
distinguished by chronological continuity. In addition, each issue bears
a lateral format continuity with other issues. For example, the basic size
and format for Eastern's Louisville and Atlanta class 6A issues dated 07-02-74 are the same. This distinguishes this category from 2A and 3A issues
which have inconsistent lateral formatting.
