New York–JFK – The tenth-largest hub for American in terms of number of flights, the ninth-largest in number of destinations and American's secondary East Coast hub for international flights. About 7 million passengers fly through JFK on American every year, or about 19,000 people per day. American has about 12% of the market share at JFK, making it the third-largest carrier at the airport behind Delta and JetBlue. Since 2017, American has been reducing its international operations at JFK, opting to expand its Philadelphia hub instead. JFK also serves as a major connecting point for other Oneworld carriers.
Airbnb is criticized for its impact on housing affordability, sparking protests, and for its related data management. 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. Landlords have been accused of illegally evicting tenants in order to convert properties into Airbnb listings. In San Francisco, the issue led to protests in November 2015.
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.
Miami – The fifth-largest hub in terms of number of flights and fourth-largest in number of destinations. About 30 million passengers fly through MIA every year on American, which is about 79,000 people per day.

To help fund the site, the founders created special edition breakfast cereals, with presidential candidates Barack Obama and John McCain as the inspiration for "Obama O's" and "Cap'n McCains". In two months, 800 boxes of cereal were sold at $40 each, which generated more than $30,000 for the company's incubation. It also got the company noticed by computer programmer Paul Graham, who invited the founders to the January 2009 winter training session of his startup incubator, Y Combinator, which provided them with training and $20,000 in funding in exchange for a small interest in the company. With the website already built, they used the $20,000 Y-Combinator investment to fly to New York City to meet users and promote the site. They returned to San Francisco with a profitable business model to present to West Coast investors. By March 2009, the site had 10,000 users and 2,500 listings.
