The second Admirals Club opened at Washington National Airport. Because it was illegal to sell alcohol in Virginia at the time, the club contained refrigerators for the use of its members, so they could store their own liquor at the airport. For many years, membership in the Admirals Club (and most other airline lounges) was by the airline's invitation. After a passenger sued for discrimination, the Club (and most other airline lounges) switched to a paid membership program.
On January 17, 2013, American unveiled a new livery. Before then, American had been the only major U.S. airline to leave most of its aircraft surfaces unpainted. This was because C. R. Smith hated painted aircraft, and refused to use any liveries that involved painting the entire plane. Robert "Bob" Crandall later justified the distinctive natural metal finish by noting that less paint reduced the aircraft's weight, thus saving on fuel costs.
Traditionally, many style guides define components as atomic components, which are then used to build more complex molecules. In theory, this works well to create coherent and flexible systems. In practice, however, what often happens is that these re-usable atoms are used many different ways, allowing all kinds of molecules to be created. Again, this opens the door for all kinds of disjointed experiences and makes the system harder to maintain.
Some cities have restrictions on subletting for a short period of time. Airbnb has published a list of regulations and requirements for cities in the United States. In some cities, collection of a transient occupancy tax by Airbnb is required. In many cities, hosts must register with the government and obtain a permit or license. Landlords or community associations may have restrictions on short-term sublets.
