It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

It's kindof ridiculous that your system is even asking me about this since my flight was canceled and I wasn't rescheduled.

You was on strike and I had to get another r flight and you did not give me my money back

Bad service as well. Another 3hr delayed flight from chicago to Charlotte.

the seats aren't the most comfy -- too little padding and I could feel whatever the passenger behind me was doing. Otherwise, it's all good.

Just kinda of a bus ride … we could do better. Delay in the flight :(

Terrible. 3 missed flights and 24 hours delayed with lost bag and promised $100 compensation from United and absolutely nothing from them…

I can't say as it was cancelled and rerouted to Toronto. I had an unexpected 10 hour layover there. A new delay every hour, Flights overbooked. Misinformation given from registration to help desks. A long exhausting day of travel on the way home.

flight was delayed 6 hours for weather, then cancelled because of the crash in toronto, but none of the links to cancel or rebook my flights are working

Air Canada is the worst airline I have ever flown. They lost my luggage, cancelled my flight, refused to pay for a hotel, charged me for business class even though they changed my flight to economy and there is no process to get someone on phone. Would not recommend Air Canada to my worst enemy.

Minimal food offered (crackers). Had to clean the seat with a wet wipe because of dried food.
