Arriving at Chicago (ORD) FAQs

Book these fares via airline websites, fare-aggregator platforms, or travel agents and confirm baggage and change fee policies, as low-cost economy fares often limit flexibility. Compare total trip cost including baggage and seat fees to ensure you’re getting the best value.
Cheapest Economy Fare (ECO) arrival searches commonly highlight high-demand leisure and business gateways like Orlando, Las Vegas, New York City, Los Angeles, Miami, and Dallas. These markets often have multiple carriers and high seat capacity, which drives down economy pricing. When searching, include these city modifiers to locate the best economy deals.
To ensure you book the cheapest economy class for an ECO arrival, compare multiple airlines, check different fare classes (basic, standard, premium economy), and factor in all ancillary fees like checked bags and seat selection. Use fare calendars, set alerts, and try flexible dates or nearby airports for the lowest all-in price. Consider weekday travel and red-eye flights for additional savings.
