Flight from Toronto Pearson Airport to Chicago O'Hare Airport

BrianFlew with Air CanadaYYZ-ORDOct 2024

Be prepared for a labyrinthine experience traversing the various levels and passages of the Toronto airport. Bring quality walking shoes, as it is likely well over a km in total walking time.

Jo AnnFlew with Air CanadaYYZ-ORDJun 2024

It seemed that anyone who checked a bag was able to retrieve it quickly.

Verified travelerFlew with United AirlinesYYZ-ORDMar 2024

Carry-on baggage sizing for United US bound flights appears to be much smaller than for Canadian flights, which forced me to check my bag at the last minute. So check online ahead of time

Verified travelerFlew with Air CanadaYYZ-ORDFeb 2024

I would definitely choose Air Canada over dirty old United airplanes any day.

Verified travelerFlew with United AirlinesYYZ-ORDDec 2023

The departure time was very convenient with the United.
