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.

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
