In November 2012, Airbnb acquired NabeWise, a city guide that aggregates curated information for specified locations. The acquisition shifted the company focus toward offering hyperlocal recommendations to travelers. That same month, Airbnb launched "Neighborhoods", a travel guide of 23 cities that provides in-depth information via collaborative filtering to help travelers choose a neighborhood in which to stay based on criteria such as public transportation, dining, peace & quiet, nightlife, tourist attractions, and shopping.
American Airlines allows all children ages seven days and older to travel on both domestic and international flights. Infants under the age of two may travel on either an adult's lap or in a designated seat. Infants traveling on an adult's lap may be required to have a ticket purchased at a discounted fare. Infants traveling in their own seat must have a ticket and must be in a safety seat approved by the Federal Aviation Administration (FAA).
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.
