American Airlines was founded in 1926 as a mail carrier with its first flight by Charles Lindbergh. Eight years later, the company switched revenue sources from mail to passengers and has since grown through various mergers with other airlines. Today, American Airlines operates out of ten hubs located from shore to shore in the United States, with its main headquarters in Fort Worth, Texas. Other hubs include Charlotte, Chicago-O'Hare, Philadelphia, Miami, Phoenix-Sky Harbor, Washington, DC-National, Los Angeles, New York-JFK, and New York-LaGuardia.
American Airlines allows all passengers to bring one carry-on bag and one personal item on all flights. The maximum dimensions for personal items are 18x14x8 inches and must fit in the seat in front of you. Certain infant necessities and medical equipment are also allowed as needed. Carry-on bags may not exceed 22x14x9 inches and must fit in the sizer at the airport. Bags that do not fit in the overhead bin or under the seat will need to be checked.
Guests can search for lodging using filters such as lodging type, dates, location, and price. Before booking, users must provide personal and payment information. Some hosts also require a scan of a government-issued identification before accepting a reservation. The company also provides travel guides, entitled "Neighborhoods", which provide details about staying in specific neighborhoods in various major cities.
