The Houston–Chicago route
George Bush Intercontinental (IAH) to O'Hare International (ORD) covers about 926 miles. Nonstop IAH–ORD is often on the schedule, about 2.5 hours airborne over 926 miles. This page is a US-market guide in USD — not a ticket and not a live calendar.
For IAH–ORD we show about $69 on the low end and around $115 as a more typical one-way economy total, USD, last reviewed August 2026. A $69 one-way is a sale-shaped guide, not a fare you can screenshot and demand. Taxes, bags, and seats change what you pay on the seller site.
Search IAH to ORD on Azurovia, compare airline-direct and travel-site totals on the same flights, then finish with the seller. We do not ticket. Keep their confirmation for changes.
Distance and time IAH–ORD
Great-circle distance IAH–ORD is about 926 miles. Block time on a nonstop is typically near 2.5 hours; wind, routing, and which runway you use still move the clock. Connections on the same city pair add layover time on top of that flying.
IAH and ORD typically share the same standard-time offset (America/Chicago). Daylight saving can still split them for part of the year — check the local times on the itinerary, not a screenshot from last month.
When IAH–ORD has a nonstop, that is usually the cleanest product. One-stop options still appear — they are worth opening only if the USD total is materially lower after you count the extra ground time.
Airports for Houston to Chicago
Both ends are in the United States: George Bush Intercontinental (IAH) to O'Hare International (ORD). This is not an international itinerary, so the usual domestic bag and ID rules apply at the seller. Alternate metro airports can still beat this pair on price.
IAH is the only origin code we list in this metro. On arrival, MDW (Chicago) can price differently from ORD. A cheaper nearby airport only wins if the transfer still fits your plan. Search with “include nearby airports” when you want those codes in one results list.
