Get to the airport early if you don’t have Pre-Check!

IanFlew with American Airlines-Apr 2026

Lately ORD airport struggles in general often having ground stops. Construction extends travel back to airport so allow 2 hrs. Over past few months, experienced far few delays on United than AA.

Dr. JosephFlew with American Airlines-Jan 2025

Be very vigilant about the weather both in Chicago and in Dallas. Adverse weather in either area can affect the trip.
