Even though I was disappointed by not being able to get the boarding passes from Delta for Aeromexico’s connecting flight to Bogota, I had an agent greet me after customs in Mexico to issue the boarding pass so I could use the transfer flight line. Excellent service throughout the entire trip.

Confusion over my boarding pass at the Delta terminal in Detroit.

Good clean aircraft. Fairly comfortable seats. Even had a power outlet in my row. Not too bad for an aircraft from the late 70s.

for some reason, i had to pay to gate check a bag. It didnt seem like anyone else did while boarding my flight.

Nice, professional crew.

I have a dog in the plane with me. None of my flights offered to make me board first. It harder to move through the aisle by myself with my pup in her carrier and my personal effect . Some nice passengers helped me when they saw I was struggling but O feel that is the crew's job.

Flight Late by Over 1 Hour due to deicing which they should have built into their boarding time schedule and two passenger did not show up causing further delays.

Crew was great cabin service was good, entertainment was good

Start loading at 10 takeoff at 11:45 late because of loading luggage. Maybe if we start loading at 11 we would not have to sit ther for so long

No much..

To start.. due to your company combining two out going Toronto flights in Vancouver and then being late off the ground in Vancouver because if that we missed our connecting flight in Toronto to Ottawa. This in turn made us miss a very important appointment in Ottawa. I’m sure the company loves that they saved money by combining those flights however you flunked the test with me. All the corporate could care less about me missing my flight after they look at the bottom line but I will be taking my $1600 plus money elsewhere in the future because of the aggravation, frustration and I don’t care attitude that your company has provided me. I’ll I want to do is get back to Vancouver in my return flight hopefully put most likely on time with my two girls and forget that your company does exists. Thanks for the headaches and goodbye..

I liked the fact that all the movies food and beverages were included in my Plus seat.

This was my first time booking a PLUS seat and never realized that row 2A seat sucks. Its a bulkead row seat that is by the window. This seat was worse to sit in than any other seat on the plane. This seat is located were the plane starts to curve in toward the front of the plane reducing the seat width, I have a 33" waist and it was tight. The arm wrests in this row don't come up as they stow your table, as well the leg room is only as good as a regular seat because of the bulkhead location. So FYI do not book this seat on a long flight.

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

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.
