The plane (looks like a night club inside), the staff was really friendly and helpful.

Arriving to LAX, we needed to claim out luggage and move to a different terminal (which wasn't that bad). However, for some reason, we couldn't do check in via the kiosks and waited for 45+ minutes(maybe 6-7 persons ahead of us) and only 1 person handling full check in, though they had 5+ persons handling the luggage check in). Also, our TSA pre wasn't part of the reservation (didn't matter too much, line was really short).

The delay in the beginnning caused a bit of anxiety that we might miss our connecting flight which could've resulted in a missed cruise

Mediocre 2.0

Connection flight from LAX to Seattle was dropped off of booking completely. When Delta was able to fix the changes in Sydney Australia they put my husbands ticket as a standby instead of putting him in an assigned seat and reported that they couldn't fix it that we would have to wait and get to LAX before the changes could be made again. There was a one and a half hour flight delay from LAX to Seattle. From Sydney Australia to LAX entertainment system didn't work the whole entire flight, they were screaming children the entire flight, and Delta had double booked seats on several different people. There were no apologies and no compensation for any of the incidences.

Plane was nice, first time I'd been on an Airbus

Charger port was between and below the seats. I didn't think there was one but I heard the passenger behind me say where it was. I pulled out some literature about the plane and read where it was located but since I couldn't see it and could only feel it I was never able to plug my cord into the recepticle. I was very disappointed. I am 6'5" tall and weigh 250lbs. Leg room was cramped. Plane left late

Nothing.

I waited in baggage check-in for two hours. I finally got to the desk and the woman at the desk said I was actually ten minutes too late. The only reason why I didn't opt to check-in my own bags was because I have to have them check my military ID. She told me to take my bag and see if they could check it in at the gate. I finally run to the gate after waiting 20 minutes in the security line. The woman at the gate says I'm too late and gives me a new ticket. I was going to have to wait 6 hours until the next flight to Seattle. I go to the new gate and of course it was already crowded with another flight. I ask the lady at the new gate if she could hold my bag while I walk around and maybe go to the USO because I refuse to pay for 2 meals at the airport, they are way to expesive. I just wanted to wash my face, use the restroom, and maybe get something to eat. She says no. I could go back and check my bag in. So lug my bag all the way back to the check-in counter, wait in line, walk across the street, and finally get a chance to relax at the USO. Worst flight ever I will never fly Virgin America and again and they don't care about their military.

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.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
