Cheap flights from Glasgow to Chicago

Book as far ahead as you can on this route, because every option connects and the cheaper fare buckets disappear first. December is the cheapest month in the dated price view, while October, November, January, February, March, May, June, July and August also have prices shown. Midweek departures are often easier to price than weekend ones, and fares usually rise around school holidays, Christmas and the Chicago summer travel period. If your dates are flexible, compare a few neighbouring days and both destination airports before you commit.

Every option on this route connects, so the real comparison is connection time, airport and fare inclusions rather than a nonstop shortcut. The list mixes carriers commonly sold as low-cost, such as Easyjet, with network carriers such as British Airways, Lufthansa, KLM Royal Dutch Airlines, United Airlines, Finnair, Iberia and Icelandair; Aer Lingus and Emerald Airlines can fall on either side depending on the fare brand. On lower-cost tickets, bags, seats and changes are often separate; on higher fare brands, more is included. Check the fare rules for the exact flight you select, especially if two carriers are involved on one booking.

Arrange your airport transfer before you land, because Midway International and O'Hare International serve different sides of Chicago and are not interchangeable. From either airport, trains and taxis are the usual ways into the centre; check which station or pickup point your terminal uses. Watch for a terminal change if your itinerary lands at one and your hotel plan assumes the other. Keep your booking reference and terminal details handy until you are in the city.

Country facts: Wikidata

• Check what your fare includes, because lower-cost tickets often charge separately for checked bags, seat selection and changes.
• Check which destination airport your itinerary uses, Midway International or O'Hare International, before you book hotels or onward travel.
• Check connection times and whether both flights are on one ticket, since a missed connection is handled differently on separate bookings.
• Check passport and entry requirements for the United States before you pay, since rules can change.
• Check December and the surrounding months in the price calendar, because the cheapest month shown is not always the quietest travel week.
