Philadelphia – The fourth-largest hub in terms of number of daily flights, fifth-largest in number of destinations and American's primary East Coast hub. American flies approximately 20.5 million passengers a year through PHL, which is about 56,000 people per day.

We created one set of these components for phones (iOS and Android), and adapted them to tablet sizes from there. Tablet components are largely the same as those for mobile, and on a technical level the code only needs to exist once in two different styles. With this system components can vary in their look and positioning, similarly to the way responsive design works for web. Designers can then design a screen once using common components, and it can be easily adapted to different screen sizes as well as to iOS and Android.
The two organizations from which American Airlines was originated were Robertson Aircraft Corporation and Colonial Air Transport. The former was first created in Missouri in 1921, with both being merged in 1929 into holding company The Aviation Corporation. This in turn, was made in 1930 into an operating company and rebranded as American Airways. In 1934, when new laws and attrition of mail contracts forced many airlines to reorganize, the corporation redid its routes into a connected system, and was renamed American Airlines. Between 1970 and 2000, the company grew into being an international carrier, purchasing Trans World Airlines in 2001.
While creating these components, we collected them in a master file called the library, which we referred to throughout the design process. After a week or two we began to see huge leaps in productivity by using the library when iterating on designs. One day, while putting together a last-minute prototype, our team was able to create nearly 50 screens within just a few hours by using the framework our library provided.
In February 2011, Airbnb announced its millionth night booked. In January 2012, the company announced its five millionth night booked. In June 2012, Airbnb announced 10 million nights booked, doubling business in the previous five months. Of these bookings, 75% of the business came from markets outside of the continental United States.
