American flies approximately 20.5 million passengers a year through PHL, which is about 56,000 people per day.

American Airlines' wastewater treatment plant recycles water used at the base to wash aircraft, process rinse water tanks, and irrigate landscape. That alone has saved almost $1 million since 2002. In addition to that, American Airlines has also won the award for the reduction of hazardous waste that saved them $229,000 after a $2,000 investment. A bar code system is used to track hazardous waste. It has led to reduction of waste by 50 percent since 2000.
The Admirals Club was conceived by AA president C.R. Smith as a marketing promotion shortly after he was made an honorary Texas Ranger. Inspired by the Kentucky colonels and other honorary title designations, Smith decided to make particularly valued passengers "admirals" of the "Flagship fleet" (AA called its aircraft "Flagships" at the time). The list of Admirals included many celebrities, politicians, and other VIPs, as well as more "ordinary" customers who had been particularly loyal to the airline.
Before it was headquartered in Texas, American Airlines was headquartered at 633 Third Avenue in the Murray Hill area of Midtown Manhattan, New York City. In 1979, American moved its headquarters to a site at Dallas/Fort Worth International Airport, which affected up to 1,300 jobs. Mayor of New York City Ed Koch described the move as a "betrayal" of New York City. American moved to two leased office buildings in Grand Prairie, Texas. On January 17, 1983, the airline finished moving into a $150 million ($369,000,000 when adjusted for inflation), 550,000-square-foot (51,000 m2) facility in Fort Worth; $147 million (about $361,000,000 when adjusted for inflation) in Dallas/Fort Worth International Airport bonds financed the headquarters. The airline began leasing the facility from the airport, which owns the facility.
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. The goal at first was just "to make a few bucks". 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. 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. The site Airbedandbreakfast.com officially launched on August 11, 2008. 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.
