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.

Airbnb features a review system in which guests and hosts can rate each other after a stay. Hosts and guests are unable to see reviews until both have submitted a review or until the window to review has closed, a system which aims to improve accuracy and objectivity by removing fears that users will receive a negative review in retaliation if they write one. However, the truthfulness and impartiality of reviews may be adversely affected by concerns of future stays because prospective hosts may refuse to host a user who generally leaves negative reviews. In addition, the company's policy requires users to forego anonymity, which may also detract from users' willingness to leave negative reviews. These factors may damage the objectivity of the review system.
