Flight from Chicago O'Hare Airport to Hong Kong

CFlew with Cathay Pacific-Oct 2026

Okay on boarding for both airlines. Hong Kong requires a lot of walking to make some connections, but that is the airport design with moving walkways.

LionelFlew with Cathay Pacific-Mar 2025

We chose a long layover in Hong-Kong on our way to Indonesia, on purpose (22h), and were able to do some well worth sightseeing.

DarylFlew with Cathay Pacific-Jan 2025

They are strict with carry on and they weigh it upon check in.

Verified travelerFlew with Cathay Pacific-Nov 2024

First flight to hkg but been to asia many times. Most airlines have frequent beverage service to combat the dehydration that comes with a long flight.
