Airbnb is criticized for its impact on housing affordability, sparking protests,[133][134][135] and for its related data management.[136][137] As of the beginning of 2018, several studies found that rental prices in many areas increased due to Airbnb, as landlords kept properties off the longer-term rental market and instead get higher rental rates for short-term housing via Airbnb.[138] Landlords have been accused of illegally evicting tenants in order to convert properties into Airbnb listings.[139] In San Francisco, the issue led to protests in November 2015.[140]

American's economy plus product (not to be confused with premium economy), Main Cabin Extra, is available on most of the mainline fleet and American Eagle regional aircraft with more than 50 seats. Exceptions include a majority of former US Airways aircraft (as of May 2014), US Airways Express regional aircraft, and a handful of 777-200ERs that have yet to be retrofitted. Seats range from 17.2–19.5 inches (44–47 cm) in width and have 34–38 inches (86–97 cm) of pitch, which is 5–6 more inches of pitch offered in regular economy seating.[38] American retained Main Cabin Extra when the new Premium Economy product entered service in late 2016.[40]

The airline also allows children ages 5-14 to travel alone on many flights with the purchased Unaccompanied Minor Service. The service is $150 per family, per way and includes supervision from boarding until drop-off at the destination. Please note that children ages 5-7 can only travel alone on nonstop or direct flights. The service is also available but optional for minors ages 15-17.
Shortly after moving to San Francisco in October 2007, roommates and former schoolmates Brian Chesky and Joe Gebbia could not afford the rent for their loft apartment. Chesky and Gebbia came up with the idea of putting an air mattress in their living room and turning it into a bed and breakfast.[16][17] The goal at first was just "to make a few bucks".[18][19] In February 2008, Nathan Blecharczyk, Chesky's former roommate, joined as the Chief Technology Officer and the third co-founder of the new venture, which they named AirBed & Breakfast.[17][20] They put together a website which offered short-term living quarters, breakfast, and a unique business networking opportunity for those who were unable to book a hotel in the saturated market.[21] The site officially launched on August 11, 2008.[22][23] The founders had their first customers in town in the summer of 2008, during the Industrial Design Conference held by Industrial Designers Society of America, where travelers had a hard time finding lodging in the city.[17][24]
