We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 4¼ hours):
- United Airlines — O’Hare is a United hub, so it flies the route frequently all day with the widest schedule.
- American Airlines — O’Hare is also an American hub; frequent non-stops and good connections beyond Chicago.
- Delta Air Lines — several non-stops daily, a solid full-service alternative to the two hub carriers.
- Frontier — the budget option, usually the cheapest headline fare; bags and seats are priced separately.
With four carriers and around 25 non-stops a day, there’s almost always a flight within an hour of when you want to travel — and the competition keeps fares low, especially if you’re flexible on times.
When to book & how to save
- Book 3–8 weeks ahead for the best domestic fares; this route rarely needs months of lead time except around the holidays.
- Avoid the peaks: summer, Thanksgiving week and late December are the priciest — shift by a few days if you can.
- Fly midweek: Tuesday and Wednesday departures are usually the cheapest, while Friday and Sunday cost the most.
- Compare budget vs full-service all-in: a Frontier basic fare can beat the majors, but add a carry-on and seat and it sometimes evens out — check the total.
- Consider Midway (MDW) as an alternative Chicago airport if a budget carrier prices lower there, though O’Hare has the most LAX non-stops.
Arriving in Chicago
Most flights land at O’Hare International (ORD), about 27 km northwest of downtown. The easiest way into the city is the CTA Blue Line train, which runs 24 hours from the airport to the Loop in about 45 minutes for a low flat fare (around $5). A taxi or rideshare to downtown typically costs $40–$60 and takes 30–50 minutes depending on traffic. Some budget flights use Midway (MDW) on the south side instead — check which airport your ticket lists, as they’re on opposite sides of the city.
