Flight deals from Las Vegas to Chicago

Flights searched here depart Las Vegas Harry Reid International (LAS) for Chicago O'Hare (ORD), not Midway (MDW). United, American, Delta, Frontier and Sun Country have appeared in EazAir's fare checks for this route. The O'Hare nonstop list dated 1 Sep 2026 includes Las Vegas, served by American, Frontier and United; schedules change, so read the stops on every result. At LAS, American and Delta leave from Terminal 1, United and Frontier from Terminal 3.

LAS asks domestic travelers to arrive at least 2 hours before departure, with extra time during major conventions. Its five checkpoints split three in Terminal 1 and two in Terminal 3, and wait times are posted on the airport's website. LAS says repaving in the airport connector tunnels is reducing lanes until about the end of December 2026, so the drive in may be slower. Uber and Lyft have no designated drop-off area and use the departures curbs.

At O'Hare, rideshare pickup is on the upper level: orange poles 2A to 2G at Terminal 2, with an indoor waiting area between vestibules 2A and 2D, and green poles 3G to 3K at Terminal 3. O'Hare lists no Terminal 5 pickup, which matters for Delta, since Delta says it uses that terminal. Taxi stands are on the lower-level curb outside baggage claim at each terminal. O'Hare's airline list did not load on 17 Oct 2026, so check your terminal in the airline app.

EazAir's first 21 fare checks for LAS to ORD ran from 12 Sep to 17 Oct 2026, each for the lowest one-way economy fare for one adult, departing 30 days later. Across those 21 checks there were 18 different results; at its highest, a result was at least double the lowest, which came on 14 Sep. A carry-on comes with the lowest American and Delta fares, but not with United, Frontier or Sun Country. Search your own dates, and check the final price, bags and fare rules on the partner site before you pay.

Travel tips

Arrive early for domestic flights

TSA generally recommends arriving at least 2 hours before a domestic departure, more at larger hub airports during peak travel periods.

Pack a mixed carry-on

Keep a change of clothes, chargers, and any essentials in your carry-on rather than only your checked bag, in case of a delay or a bag that doesn't arrive with you.

Ease jet lag on longer routes

On longer cross-country flights, adjusting your sleep schedule a day or two before departure and staying hydrated in flight can reduce jet lag on arrival.

Screenshot your confirmation

Save a screenshot or PDF of your booking confirmation and boarding pass before you travel, in case you lose signal or battery at the airport.

Check in online when it opens

Most airlines open online check-in 24 hours before departure. Checking in early can help with seat selection and, on some airlines, boarding group assignment.
