I had an episode of anxiety over very minor turbulence which I sometimes get and both ladies who happened to be on duty were very reassuring and sympathetic to me. I had my 6 year old daughter also on the plane who is not anxious at all, so I was able to speak to one of the staff in French so as not to transfer my anxiety to my daughter who doesn't understand French. This was great. Over half way through the flight they gave me some earphones and suggested I watch a movie. This helped so much.

Todo estuvo realmente bien con una excepción.

Cuando abordé el avión me di cuenta de que el espacio sobre uno no es necesariamente el espacio designado para su maleta de mano, ya que uní puede guardar su maleta en el espacio sobre otra persona; sujeto a la voluntad del pasajero o la disponibilidad del espacio en el compartimiento. Creo que cada pasajero debería llevar su equipaje de mano justo sobre su asiento para evitar desorden, mal entendidos o que se pierda equipaje de mano entre la confusión.

The seats were old and uncomfortable. The plane was old and had the drop down video screens. This was terrible- we couldn’t see the one closest to us, only the one further away. But any words on the further one, we couldn’t read. The staff on the plane were rude and made us seem like we’re a bother and unwelcome. We were scared to ask for anything.

Flight back was OK but flight to Orlando was not. Travelling with s 94 yr old man in a wheelchair. Everything at Pearson is not conduscent to travel with a handicapped person. Poor layout, poor assistance, non caring people, long distances,, and final straw was air canada started boarding without calling for handicapped first. We had to stop them and then fight our way up the aisle with people all in the way. Terrible, just lousey. 3 and a half hours before flight we arrived and didn't even have a chance to get some lunch before flight. I give Toronto and air Canada the worst possible rating of any airport or airline I've ever dealt with. John O"Hearn

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
