Flights to Chicago from other cities in the United States and Canada.
Flights to Chicago from just about any other major city in the country are easy and inexpensive. Chicago is a hub for several airlines, including United and American, and is home to one of the largest and busiest airports in the world: O’Hare International Airport.
Other US carriers serving O’Hare include Delta, Alaska, Continental, US Airways, and Jet Blue. Midway, Chicago’s smaller airport, is served by Southwest and Frontier.
While traveling to Chicago from a smaller city may require that you connect along the way, from larger cities like Los Angeles, Seattle, Portland, Austin, Houston, Las Vegas, New Orleans, Miami, Fort Lauderdale, New York, Boston, Atlanta, Ontario (and so on and so on) you can take a direct flight that will last under five hours.
Flights to Chicago from the Caribbean, Mexico, and Central and South America.
There are some direct routes from Mexico, the Caribbean, Central and South America to Chicago (including Mexico City and Cancun to Chicago, Montego Bay and San Juan to Chicago, and Guatemala City to Chicago), most routes from these areas involve a layover in Miami or Fort Lauderdale (from most of the Caribbean and Central America) or in Mexico City (from many spots in Mexico and South America). Stops with a layover may mean more travel time but they can be much cheaper than direct flights to Chicago.
Flights to Chicago from Europe and Africa.
There are several direct routes from European cities to Chicago, the most popular and least-expensive being Paris, London, Dublin, Frankfurt, Amsterdam, Zurich, Moscow, or Madrid to Chicago. British Airways, Iberia, Lufthansa and Air France are among the international carriers that serve O’Hare. There are virtually no direct flights from Africa to Chicago – most flights will involve a layover in either a European city or in Washington, DC.
Flights to Chicago from Asia and Australia.
While there are several direct flights available from the Asian cities of Bangkok, Beijing, Tokyo and Seoul to Chicago, they tend to be much more expensive than flights that have a layover. Most flights from Asia (particularly from smaller cities) include stops either in a larger Asian city or in Los Angeles or San Francisco. Nearly all flights from Australia or Tahiti stop in Los Angeles or San Francisco.
