Expect stable service levels with a mix of nonstop and connecting flights; Southwest commonly provides MDW service while legacy carriers may offer seasonal ORD flights.

Arrivals to Chicago in October commonly land at O'Hare (ORD) or Midway (MDW) depending on carrier and routing; expect cooler weather, possible rain, and fall colors in suburban areas.

For late-October travel, add a warmer sweater or light coat—Chicago wind off Lake Michigan can make temperatures feel colder.
Yes—October often hosts the Chicago Marathon, autumn festivals, and sometimes MLB postseason games or playoff-related travel surges which can affect arrivals, ground transport, and hotel availability.

October sees a variety of events that can influence travel between John Wayne Airport (SNA) and Chicago (All Airports) (CHIA). In Orange County and nearby Anaheim, Halloween events (Disneyland Halloween Time, Knott's Scary Farm) increase outbound travel demand.

Check event calendars when planning October flights and book lodging and transfers early to avoid premium pricing.
For the SNA to CHIA route in October, the best time to fly for savings is mid-week (Tuesday–Thursday) and outside major event weekends. Early October often offers lower fares than late October when events like the Chicago Marathon or sports playoffs can increase demand. If you want milder weather in Chicago, early October is ideal; for fall foliage and festival experiences, mid-to-late October can be attractive but pricier. Book 3–8 weeks ahead for the sweet spot between availability and price.
Choosing between direct and connecting flights for SNA to CHIA in October depends on priorities: fly direct (nonstop) for speed and convenience—most nonstop flights are ~4–4.5 hours—while connecting itineraries can reduce cost or provide better schedules. Common connection hubs include Los Angeles (LAX), Phoenix (PHX), and Denver (DEN).
