In addition, Airbnb moved its main MySQL database to Amazon Relational Database Service (Amazon RDS). Airbnb chose Amazon RDS because it simplifies much of the time-consuming administrative tasks typically associated with databases. Amazon RDS allows difficult procedures, such as replication and scaling, to be completed with a basic API call or through the AWS Management Console. Airbnb currently uses Multi-Availability Zone (Multi-AZ) deployment to further automate its database replication and augment data durability.
There was no physical Admirals Club until shortly after the opening of LaGuardia Airport. During the airport's construction, New York Mayor Fiorello LaGuardia had an upper-level lounge set aside for press conferences and business meetings. At one such press conference, he noted that the entire terminal was being offered for lease to airline tenants; after a reporter asked whether the lounge would be leased as well, LaGuardia replied that it would, and a vice president of AA immediately offered to lease the premises. The airline then procured a liquor license and began operating the lounge as the "Admirals Club" in 1939.
American also plans to increase service from its largest hub at DFW. As announced in March, the airline reached a lease agreement with the airport resulting in 15 new regional gates after renovating the Terminal E satellite, which is scheduled for completion during the summer of 2019. As part of the expansion, American will add new service to Valley International Airport (HRL) in Harlingen, Texas, beginning March 3, and launch seven additional domestic routes from DFW:
It will be located on a 41-acre (17 ha) property adjacent to the airline's flight academy and conference and training center, west of Texas State Highway 360, 2 miles (3.2 km) west from the current headquarters. The airline will lease a total of 300 acres (120 ha) from Dallas-Fort Worth International Airport and this area will include the headquarters. Construction of the new headquarters began after the demolition of the Sabre facility previously on the site.
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.
