Ten itineraries came back. The nonstop ran 4 hours 15 minutes. The connections ran 9 hours 7 minutes to 9 hours 37 minutes, so a single stop cost about five extra hours. Only one connection undercut the nonstop, and only by a few dollars. The other eight cost more and still took twice as long. That one cheap connection is the problem. The fare list above runs cheapest first, so it takes the top row, and a nine hour journey is the first thing you see on a route where the 4 hour 15 minute option costs about the same. Check the journey time beside each price before you pick. Fares move daily, so treat this as the shape of the decision rather than today’s number.
All ten. Nonstop and connections alike. That’s one search on one pair of dates, not a statement about who flies this route, and it’s worth knowing before you assume you’ve seen the whole market. Run your own dates in the search above and see what comes back.
The search covers both, and you shouldn’t treat them as the same airport. They sit on opposite sides of the city, roughly 25 miles apart. Work out which one you can actually reach before you start comparing fares, then search that airport on its own by entering ORD or MDW in the box above instead of Chicago. A fare that saves a few dollars and adds a long trip across the city has not saved you anything.
No. In our 27 October 2026 search only one of the nine connecting itineraries cost less than the nonstop, and only by a few dollars. The other eight cost more and took more than twice as long.
About five hours. On 27 October 2026 the nonstop ran 4 hours 15 minutes and the connections ran 9 hours 7 minutes to 9 hours 37 minutes.
Whichever you can reach more easily. They’re about 25 miles apart on opposite sides of Chicago, and that gap often matters more than the fare difference between them. Enter ORD or MDW in the search above to price one airport on its own.
Every itinerary our 27 October 2026 search returned was Frontier. We only name carriers we’ve actually seen in our own results, so run your dates above to see which airlines come back for them.
We don’t have enough observations on booking lead time for this route to give you a number, and we’d rather say so than invent one. Compare a few sets of dates in the search above instead.
