Major events and festivals significantly affect economy fares: Chicago's Lollapalooza and Taste of Chicago spike inbound demand, while destination festivals (e.g., Miami Art Basel, New Year’s in New York) push up arrival prices. For cheapest economy travel, avoid major local event weekends or book months in advance. Secondary dates surrounding the event can sometimes offer lower fares while still enabling attendance.
The best time to fly cheaply from Chicago is typically during shoulder months (February, April, September, October) and midweek (Tuesday–Thursday). For domestic economy fares, book 6–8 weeks ahead; for international routes, aim for 2–4 months in advance. Avoid holiday weeks (Thanksgiving, Christmas, Fourth of July) when fares spike. Use flexible-date search tools to find the lowest-priced days within a month and set price alerts to buy when fares drop.
Nonstop flights save time and reduce the risk of missed connections, but they are frequently more expensive in economy class. Connecting flights can be significantly cheaper and expand route options — ideal for budget-conscious travelers willing to trade time for price. When selecting a connecting itinerary, allow sufficient layover time (90–120 minutes domestic, 2–3 hours international). Consider the reliability of the connection hub; larger hubs may offer more contingency options if you miss a connection.
Major carriers (United, American, Delta) offer broad route networks and more flexible ticket options but often at a higher base fare; they can be a better value for international economy travel when baggage is included. Low-cost carriers (Southwest, Spirit, Frontier) often provide the lowest base economy fares from Midway and secondary routes but charge extra for bags and seat assignment. Southwest includes two free checked bags on many fares, improving true economy value for luggage-heavy travelers. Compare total out-the-door price (fare + bags + seats) before booking.
Winter: Pack warm layers in carry-on and allow extra time for de-icing delays; book flexible or refundable fares if traveling during severe-weather months. Spring & Fall (shoulder seasons): Take advantage of lower economy fares, less crowded airports, and pleasant weather. Summer: Book early for peak routes and consider midweek travel to reduce costs. Festivals/Holidays: Avoid peak dates or book far in advance and factor in premium economy pricing for these periods.

Connecting flights add layover time; aim for 90–120 minutes minimum for domestic connections and 2–3 hours for international transitions when checking bags. Red-eye flights can save money and maximize daytime in destination cities but may be less comfortable for some travelers.
