Flight from Denver to Chicago O'Hare Airport

JoanneFlew with United Airlines-Jun 2026

The runway to gate took a bit of time. So if you have a short layover pay for a seat up front .

AdamFlew with Southwest-Oct 2024

Arriving T5 at ORD on Southwest is often a LONG walk, with no moving walkways going out, to baggage claim / pickup.

BrianFlew with United Airlines-Jan 2024

Big airport. Make sure you have enough time between flights for rest, eating, etc…
