The late departure Of two hours waitresses, immature, and gossiping

It was upsetting that the flights were canceled but that was due to weather. I did not receive any vouchers for food or a hotel stay when I was forced to spend the night in Montreal. I was also upset when my seat was changed many times.. The plane seemed old with a non-functioning screen and loose side pockets.. All in all in need of updating. On the positive side, the staff in areas was friendly and helpful.

The flight got canceled multiple times and we had to drive their to reach midnight for our next morning interview. Poor and unriable experience. Now have to ask for a refund since we didn't need their rescheduled flight three days later.

I love flying with AC. I love that they have power outlet and free messaging wifi for aeroplan members.

Nice small trip, No food included in ticket, but beverages were for free.

All of our flights got delayed. Fll-Montreal delayed due to technical issues. We got transferred to a Fll-Toronto flight, in Toronto flight got delayed 5 hours causing us to miss our connection to Amman. We are now arriving to Amman 24hours later

In flight wifi that I paid for was very slow and at times didn't work at all.

Flight delayed two and a half hours from Toronto to Calgary Philadelphia to Toronto we were listed as standbys !!! Very concerning

Flight delayed at the last moment Hill next day and havé to drag at Hotel at our cost and bec day was again delayed 4 Times because no crée and no pilot

Flight schedule could be better. Leave Montreal early in the morning and return from LAX later in the day
