economy plua has a reasonable amount of room, good food for breakfast, nice movies in flight.

they canceled our flight to hanaeda and instead had us take an hour later flight to narita which is a 1 1/2 hour $30 bus ride away which they don’t pay for. this caused us to miss our connecting flight to Asahikawa, the last flight of the day. The connection time allowed was not nearly enough even if the plane had not been an hour late and there are no flights to asahikawa from narita. yo have to transfer to hanaeda. remind me not to fly United to Tokyo again as I’m pretty sure the flight was canceled because it was not full enough. Even the narita flight with all the hanaeda passengers rebooked on it was not full. So i suspect this may be a relatively common occurance on the hanaeda flight.

Service, boarding, pilot capability; all positive things with no complaints. And yeah, I got the whole can of soda.

As a tall fellow of 6'3'', Seats on united are very close together and knees are constantly under pressure from the seat in front.

Our Delta plane was brand spanking new. Everything worked and the inflight entertainment system was fantastic with many movies to choose from, free headphones, games, tv shows, etc. The crew was polite and the seating at least as comfortable as expected for a 4 hour flight.

The restrooms in the rear of the plane were remarkably small, even by airline standards. I'm a somewhat larger person and I fit, but I know a lot of people who would literally not be able to fit on the toilet without touching both of the sidewalls or risk getting stuck in there. The boarding process at San Jose Del Cabo was the most ridiculous setup I've ever experienced. There were numerous flights boarding out of the same gates and at least 3 or 4 lines for different destinations forming on a ramp just outside the gates. There were guys with signs trying to herd people into the correct lines and then loading the people onto buses which took you out to the planes. The planes were loading from both the front and rear doors and people were getting tangled up inside because of the haphazard loading process. Very easy for a person to end up on an incorrect plane!!

On time departure, actually got to Cabo early.

The seat in front of mine had a broken reclining lock mechanism and the passenger kept trying to switch from recline to sitting up and it wouldn't latch in the upright position, so he kept jerking the seatback up and down for the entire 4 hour flight. Also the rows were so tight, and seatbacks were so close together, that the reclining seat in front of me was 6 inches from my face.

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.
