firstclass

Firstclass, often written as first class or FirstClass, is a term with multiple meanings across domains, including transportation, postal services, and software. In general usage, the phrase denotes the premium tier or fastest service within a system, and it also appears as a brand name in some contexts.

Transport and travel: First class is the highest level of service offered on many trains, airplanes, ships, and other passenger services. It typically includes greater seating space or privacy, enhanced meals or amenities, and benefits such as priority check-in or boarding. The specifics of what is included, and how it is priced, vary by carrier, country, and service type. Some operators have renamed or restructured their branding, merging first class with other premium categories.

Postal and shipping services: First-class is a designation used by postal systems for faster processing of mail. In many countries, First-Class Mail covers letters and small parcels with quicker handling than standard or economy options, with rates influenced by weight, size, and destination. Some services also offer First-Class International for cross-border items, which typically carry different timelines and customs requirements.

Software and brands: FirstClass is the name of a networked groupware and e-mail system that was widely used in educational and organizational settings during the 1990s and early 2000s. It provided features such as messaging, forums, calendar sharing, and file exchange across multiple platforms. The product line declined as newer collaboration tools emerged and has largely been superseded by modern platforms.
