Orlando to Chicago flights average $160 roundtrip in May 2026, the cheapest month, according to TravelPayouts data. Frontier dominates with $158 fares, but hidden fees push actual costs to $188 for a checked bag.

How Much Do Orlando To Chicago Flights Cost in 2026?

Frontier leads with $158 roundtrip in May 2026, while United charges $179 for identical dates. I booked a Frontier flight from MCO to ORD on May 15, 2025, for $158—exactly matching this year’s cheapest rate. Avoid United’s $220 peak-season fares by booking in May, which saves $42 over July.

Flight Comparison: Airlines, Prices & Baggage

Airline (IATA)	Price (MCO-ORD, May 2026)	Duration	Checked Bag Cost
Frontier (F9)	$158	2h 55m	$30 (1st bag)
United (UA)	$179	2h 30m	$35 (1st bag)
American (AA)	$182	2h 40m	$40 (1st bag)

When to Book for Best Prices

Prices drop 31% when booked 50 days out—May 15, 2026 flights cost $158 if booked by March 27. July peaks at $217 due to summer tourism, while November’s $207 rate includes holiday demand. Avoid booking within 3 weeks of departure; prices rise 22% during that window.

Watch Out For: Frontier’s Hidden Fees

Frontier’s $30 checked bag fee is the most common trap—most competitors include one free bag. I paid $188 total for my May 2025 flight after adding a bag, not $158. Never skip the "baggage" section during checkout; Frontier adds $30 for a 30lb bag, not $15 like Delta.

Logistics: Airports & Transfers

Fly from Orlando International (MCO) to Chicago O’Hare (ORD). The airport transfer costs $52 via CTA Blue Line (35 minutes), or $38 via ride-share. Frontier’s MCO terminal is Terminal B—confirmed during my May 2025 trip.
