Air conditioning was out for about 15 minutes that made it uncomfortable. WiFi went out halfway into the flight. Flight was about 45 minutes late.

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.

Good service, friendly staff. Food was average for airlines and the seats were small.

Flight delayed, missed connection, had to stay overnight. Next flight instead of our business class we were booked on the very back row. Second time this had happened in 2 months.

Due to the long delays and rescheduling boarding was horrible. However, the gate staff and the flight attendants went above and beyond to remedy our frustrations. They were able to handle every potential harsh situation with Grace, compassion and coolness of head. Kudos to the MIA Gate A12 and night crew of flight 1572 YYZ to MIA.

I liked nothing about this particular flight. Not only it was initially delayed for two hours due to late arrival of the plane, but the flight attendants were also very late to show up coming from a hotel (based on the announcement made by the gate agent). They did not arrive on another late flight, so why couldn't they be on time? Total disrespect of the passengers!! The plane itself was cramped and the seats super uncomfortable. To top off the poor experience, my video screen did not work. To summarize: flight delayed for 3 hours, cramped and no entertainment (for me).

They kept posting delaying flight due to maintenance issues from incoming arrival flight since 10am, the flight is supposed to depart at 3:45pm, after kept delay until 12am, they finally said it’s canceled. What were they doing for the last 13 hours? After 2am, they still don’t find hotel where we can stay. terrible experience!

lounge was the highlight - seats weren't that comfortable - it was a full flight but no complaints

The flight was delayed multiple times. I had to buy a new tickets (4 tickets) for my family for a total of $5200 cnd And missed thanks giving with our family. Very very poor and disappointing service.
