Cheap Flights from Chicago: Complete Budget Guide (2026)

Here is something most people do not know: Chicago to Warsaw on LOT Polish Airlines routinely goes for $400-500 round-trip in shoulder season. Four hundred dollars to Eastern Europe from the middle of the United States. From Warsaw, you can be in Krakow for $20, Prague for $25, Budapest for $30 on a budget carrier. That math changes everything about how Midwesterners should think about international travel.

O'Hare is massive, United has a fortress hub, and the competition from European and Middle Eastern carriers keeps prices honest. If you live anywhere between the Rockies and the Appalachians, Chicago is probably your best bet for getting overseas on a budget.

Two Airports, Clear Roles

ORD (O'Hare) — Everything international. United hub. LOT Polish, Icelandair, Turkish Airlines, Aer Lingus, Emirates. Blue Line to downtown costs $2.50 and takes 45 minutes. Terminal 5 for international is a serious trek from domestic terminals — budget 90+ minutes for connections.

MDW (Midway) — Southwest's hub. Budget domestic carriers and some Mexico/Caribbean. Orange Line to downtown, $2.50, 30 minutes. Smaller and less soul-crushing than O'Hare.

Chicago to Europe — Eastern Europe Is Your Secret Weapon

Underrated transatlantic market. Particularly strong for Eastern European connections that cost a fortune from other US cities.

What You Should Expect to Pay (Round-Trip)

The Airlines Worth Knowing

LOT Polish (Star Alliance) — Direct ORD to Warsaw. This is the route. Often $400-500 round-trip in shoulder season. Warsaw is a gateway to everywhere in Eastern Europe — Wizz Air and Ryanair will take you anywhere from there for pocket change.

Icelandair — ORD to Reykjavik. Free Iceland stopover. Solid connections to Scandinavia and the UK.

Turkish Airlines — Via Istanbul to everywhere. Excellent value for the Mediterranean, the Balkans, and honestly most of Europe. Istanbul itself is worth the layover.

Aer Lingus — Direct to Dublin. US preclearance in Dublin means you skip immigration when you get home. That alone is worth something.

Chicago-Specific Moves

LOT Polish is the cheat code — Chicago to Warsaw is consistently one of the cheapest transatlantic routes from the US. Use Warsaw as your Europe entry point.

Midway for Mexico — Southwest and Spirit from MDW often undercut ORD pricing on Mexican destinations.

Brutal winters, aggressive deals — Airlines price aggressively in January and February to fill planes while Chicago is uninhabitable. Take advantage.
