a carrier's complete schedules.
Carrier's main timetable.
Due to language or alphabet restrictions this may not be the nominal edition

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.
Home System. Corresponds to category 1A. Usually
used when 1A not practical due to language or other marketing consideration.
System schedules separated
in multiple concurrent editions. Each of the component timetables but be used to
view the carrier's full system. For example, Air Canada's North American and
International timetables issued during the 1960s and 1970s.
System schedules presented in an edition intended for
distribution in single locale.
CLASS 2 - REGIONAL TIMETABLE

Distributed in other countries.
CLASS 6 - USA CITY QUICK REFERENCE
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.

Timetables include combined schedules of all carriers serving a
specific city(s) or airport(s). Usually issued by local civic or airport

CLASS 13 - ELECTRONIC TIMETABLE
