I like Virgin, from their on-boarding experience, to the over-the-top safety video! This flight was pretty easy for us, after a somewhat grueling (and frigid trip). They got us home quickly.

We love everything about Virgin and don’t want Alaska to change a thing. One of the gate agents set us up to check our stroller before they even began boarding. They were so kind and understanding to us as a family traveling with a toddler. I hope Alaska gives priority boarding to families with small children, and to their credit card holders.

Flight itself was comfortable, as usual with Virgin.

Three hour gate delay. Another half an hour on the tarmac before takeoff. Then almost an hour of slowdown and vectoring before landing. Not Virgin's fault, most likely, but it sucked.

Absolutely nothing.

Seats have little to no cushioning. Seats don't recline. Checked bag is a gimmick. You cannot check it in if your fight is delayed and the airport checking machines dont operate after certain time. You will have to carry it on and that means loosing all your liquids.

The flight was delayed 5 hours, and we were offered a $100 voucher that would be emailed to us immediately after the flight takes off. I approached the desk to verify with an employee pre-boarding to ensure I will receive this voucher. She was annoyed with me from the start repeatedly saying it will be emailed after takeoff, which was NOT my question. My question was to verify that the email on file was correct. She had a very hard time getting this to her head. However, it has been over a week and I have yet to receive this voucher. Unless, I receive this voucher I will never recommend this airline.

We regained time despite the delay. Free beverages.

We were an hour delayed. The screen at my seat was broken so that I couldn’t stow it properly it was always out and the brightness couldn’t be adjusted. I really wish Virgin gave snacks or at least had some good vegetarian savory meal options. I am also disappointed to see that Virgin doesn’t give free WiFi for messaging like Alaska does.

The gate agent was funny, the flight crew uniforms were stylish, I noticed the cool lighting immediately upon boarding, and loved the individual screens. The safety video was fun and informative, and I got to enjoy two awesome recent release films. Fantastic first flight with Virgin America!

The gate area didn’t have enough seats, and boarding was a mess. We were in boarding group A but it felt like half the flight was seated before we made our way through.

My first flight was canceled without notice, it was a 1:30AM flight. Had to sleep in the check in area of the airport until we could get our next overpriced tickets that will not be taken care of by their 3 options they give you. This shouldn't have been placed as the cheapest tickets available with out big red warnings that it is only cheap if you have no bags. $40 more would have given me free check in bags and a far better in flight experience on another airline.

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.
