Airbnb has grown significantly over the last 3 years. To support demand, the company uses 200 Amazon Elastic Compute Cloud (Amazon EC2) instances for its application, memcache, and search servers. Within Amazon EC2, Airbnb is using Elastic Load Balancing, which automatically distributes incoming traffic between multiple Amazon EC2 instances. To easily process and analyze 50 Gigabytes of data daily, Airbnb uses Amazon Elastic MapReduce (Amazon EMR). Airbnb is also using Amazon Simple Storage Service (Amazon S3) to house backups and static files, including 10 terabytes of user pictures. To monitor all of its server resources, Airbnb uses Amazon CloudWatch, which allows the company to easily supervise all of its Amazon EC2 assets through the AWS Management Console, Command Line Tools, or a Web services API.
Main Cabin passengers will also receive complimentary snacks and soft drinks or even full meals on transcontinental flights. Additional food and drinks are also available for purchase on many routes.

The second Admirals Club opened at Washington National Airport. Because it was illegal to sell alcohol in Virginia at the time, the club contained refrigerators for the use of its members, so they could store their own liquor at the airport. For many years, membership in the Admirals Club (and most other airline lounges) was by the airline's invitation. After a passenger sued for discrimination, the Club (and most other airline lounges) switched to a paid membership program.
