Best Time to Book and Travel

Best booking window: 1–3 months ahead for domestic travel, with many experts recommending around 40–60 days for this route.

Best travel periods:

  • Shoulder seasons (April–June and September–October) offer good weather and lower crowds/prices.
  • Avoid peak summer (July) and major holidays if possible.
  • Chicago’s fall (especially September–October) is beautiful; winter travel (Nov–March) can be cheaper but carries higher risk of weather delays.

Choosing Between O’Hare (ORD) and Midway (MDW)

Factor O’Hare (ORD) Midway (MDW)
Size & Crowds Very large, busier Smaller, often quicker through security
Flight Options More airlines and frequencies Primarily Southwest non-stops
Distance to Downtown ~17–19 miles northwest ~8–11 miles southwest
Public Transit CTA Blue Line (40–45 min) CTA Orange Line (20–25 min)
Best For More schedule choices, international connections Simpler experience, good Southwest deals

Many travelers prefer MDW when flying Southwest because it feels less overwhelming and the train ride downtown is shorter.

Essential Tips for a Smooth Boston to Chicago Flight

  • Arrive early at BOS: Plan to arrive at the airport 2 hours before domestic departure. Logan can get busy, especially during peak hours.
  • Download the free FlyLogan app for real-time flight status, navigation, and ground transport info.
  • Consider TSA PreCheck or CLEAR — both airports are busy and these programs save significant time.
  • Baggage: Southwest includes two free checked bags. Other carriers may charge for checked luggage on basic economy fares.
  • Track your flight and set up alerts. Weather at either end (especially Chicago winters or summer thunderstorms) can cause delays.
  • Allow extra time for security and walking at ORD — it’s a large airport.

Ground Transportation at Both Ends

  • Taxis and rideshares (Uber/Lyft) are readily available but more expensive.
  • Logan Express buses serve suburban areas.

From Chicago airports to downtown:

  • ORD: CTA Blue Line train runs 24/7 directly from the airport to the Loop (40–45 minutes, ~$5).
  • MDW: CTA Orange Line to downtown (20–25 minutes, similar low fare).
  • Taxis: ~$40–60 from ORD, ~$25–40 from MDW (plus tip).
  • Rideshares are convenient but watch for surge pricing during bad weather or events.

  • Fall: Generally the most pleasant and reliable weather window.

Always check the forecast and flight status the day before travel.
