Westbound flights often take slightly longer due to prevailing headwinds. There are dozens of daily departures, with the first flights often leaving as early as 5:00 AM and red-eye or late-evening options departing around 9:00 PM. This high frequency makes it easy to find a schedule that fits your needs.
Nonstop vs one-stop options
For the fastest travel, ORD to MIA nonstop flights are the gold standard. However, travelers looking for lower fares might consider one-stop options.

Passengers can choose between Basic Economy, Main Cabin, Main Cabin Extra, and Domestic First Class. Their Boeing 737-800 and 737 MAX 8 aircraft are the workhorses for this corridor.

Spirit and Frontier (Low-Cost Carriers)

Cabin classes and seat tips
If you are flying a legacy carrier, try to book Main Cabin Extra or Economy Plus for additional legroom, which is valuable on a three-hour flight. On the 737 aircraft, exit row seats provide the most stretch-out space, though they often do not recline fully. If you prefer a quiet flight, avoid the rows near the galleys and lavatories.
Departure Airport Guide: ORD
Terminals and check-in
O Hare International Airport (ORD) is a sprawling complex. American Airlines operates primarily out of Terminal 3, while United occupies Terminal 1. Delta and most international or low-cost carriers use Terminal 5. Always check your terminal before arriving, as the Airport Transit System (ATS) is required to move between the domestic terminals and Terminal 5.

The CTA Blue Line is the most cost-effective way to reach O Hare from downtown Chicago, taking about 45 minutes for a $5 fare. For those coming from the suburbs, Metra North Central Service provides weekday trains to the O Hare transfer station.

Parking and rideshare pickup
Rideshare services like Uber and Lyft pick up at the Upper Level between Terminals 1, 2, and 3, or at the dedicated zone in Terminal 5. For parking, the Economy Lots (F and G) are the most affordable, connected to the terminals via the ATS shuttle train.

American Airlines occupies the North Terminal (Concourse D), while most other domestic carriers use the Central Terminal (Concourses E, F, G). Baggage claim is located on the lower level. MIA is a large airport, so expect a fair amount of walking from the gate to the exit.

From there, you can catch the Metrorail Orange Line into Downtown Miami or the Miami Beach Airport Express bus for a direct ride to the beach.
