AAdvantage is the frequent flyer program for American Airlines. It was launched on May 1, 1981, and it remains the largest frequent flyer program with over 67 million members as of 2011. Miles accumulated in the program allow members to redeem tickets, upgrade service class, or obtain free or discounted car rentals, hotel stays, merchandise, or other products and services through partners. The most active members, based on the amount and price of travel booked, are designated AAdvantage Gold, AAdvantage Platinum, AAdvantage Platinum Pro, and AAdvantage Executive Platinum elite members, with privileges such as separate check-in, priority upgrade and standby processing, or free upgrades. They also receive similar privileges from AA's partner airlines, particularly those in oneworld.
Designers were also excited about the system. It enables product reviews to focus on the actual concepts and experiences of a design, rather than padding, colors and type choices. The DLS provides us with a shared understanding of our visual style, and streamlines contributions to a single system. This system also enables all of us to prototype and experiment with ideas in high fidelity faster and at a lower cost.

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.
