In November 2012, in the aftermath of Hurricane Sandy, Airbnb partnered with New York City Mayor Michael Bloomberg to offer free housing for persons displaced by the storm. Airbnb built a microsite for this effort alone where victims register for housing and meet property owners with free housing. Additionally, Airbnb waived all service fees associated with these listings while maintaining the Host Guarantee for all properties listed.
The European Union (EU) warned member states against banning sharing businesses like Airbnb and Uber, stating that outright bans should be used only as a last resort to attain public interest and that governments should instead implement more moderate regulations, which the sharing companies have had to navigate through. The European Commission advocated the EU's guidelines on regulating sharing businesses companies and warned that they were pulling massive revenues generated estimated at around 28 billion Euros across Europe.
Due to the growth of international end-users, in early 2012, Airbnb opened offices in Paris, Milan, Barcelona, Copenhagen, Moscow, and São Paulo. These openings were in addition to existing offices in San Francisco, London, Hamburg, and Berlin. In September 2013, the company announced that it would establish its European headquarters in Dublin. Prior to the 2012 Summer Olympics, Airbnb acquired London-based rival CrashPadder, subsequently adding 6,000 international listings to its existing inventory. This acquisition made Airbnb the largest lodging website in the United Kingdom.
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.
