Peak season:

If you’ve been to New York then why not book cheap flights to Chicago, the nation’s second city? The skyscraper metropolis is a feat of modern architecture, as well as home to what was once the world’s tallest building, Sears Tower. It is not a traditional tourist destination but as the hub of the Midwest, Chicago much to offer as a holiday destination. Featuring world-class art galleries and science museums, huge parks and sandy beaches, it also has a multicultural vibe (thanks to the Poles, the Italians, the Greeks and the Irish among many other groups). Peak tourist season is summer (June to August). This coincides with the festival season with many major events taking place in Chicago parks and neighbourhoods every weekend, in spite of the heat and humidity. Taste of Chicago, an outdoor food festival which showcases the variety of cuisines and local flavours, is in mid-July at the lakefront. If you book flights to Chicago during this popular festival, expect crowds of visitors in the area and a rise in the price of flight tickets. August is host to another popular event – the Chicago Air and Water Show. With its free admission and lakefront location, the show attracts huge numbers of fans of aviation and adventure seekers.
