I wish I could give food 6 stars! Best airline food ever! They partner with delta for USA domestic flights, if outshine delta in every way!

I was really worried about being on a plane for 14+ hours, but it was great! It was very comfortable with plenty of room. They also had the best airline food I've ever tasted! I will fly virgin Australia again!

Everything was absolutely wonderful. No complains here!

The plane and flight attendants were just great. The food was great as well.

My grandmother had a terrible experience getting from check-in desk to the plane. We were made to feel she was an inconvenience due to her disability. She wasn't provided a wheel chair service in a timely manner, attitude when asking why service was so delayed, and it was not acceptable that she had to walk from the bus to the plane, having to walk up the platform to the plane door. I really think Virgin Australia should educate their employees on how to accommodate those who are less able bodied.

I was traveling for medical reasons and the Delta crew took great care of me, made sure I was at my connecting gate on time, and even put me in a better seat on the plane. Not sure if that was a coincidental upgrade, or intentional, but it was perfect.

I dint know i needed a chinese visa to travel to shanhai, My flight began on denver then seattle and from seattle i wasnt able to fly to china. I received no help at all, all they did was cancel my booking not received any kind of refund and i got stuck in seattle, i had to buy new tickets to go back to denver after losing my flights and not getting a dime back, this is unacceptable!

Everything was excellent , no complaints at all. Staff friendly and efficient,food was pretty good , wine nice good flight .

Not enough good new release movie selection was very average/ poor. Your boarding from LAX could be improved. You have two signs about Premium and economy lines for boarding! These are not obvious . There needs to be a staff member or two checking people as they arrive in a line to check they're in the correct t line . Otherwise people don't trailer until they have been in the wrong line until the reach the top of the line . Leads to frustration even before the flight begins! Otherwise great job everyone ! Thank You !

Boarding is an issue. Please have more staff in the early stages of boarding to make sure people go to the correct lines . It's not immediately obvious and leads to frustration . I wasn't too bothered as I worked it out quickly but I could hear many others expressing their frustration around me . I was disappointed in the movie selection. I wanted more new release movies to choose from . Cabin crew friendly and polite . Love the wine ! Put up with being cramped .. would love more leg room but overall very happy ! Thank You everyone involved !

Again, cabin crew is friendly and no last minute gate changes,

The food was gross, which could be a just a cultural difference in food tastes. There were no functioning USB charger ports on the return flight even though the ports were present. No wifi, which is a first. Most airlines I fly on these days always have some type of wifi. Lastly, the 'touch-screen' on the seat for entertainment barely worked. Buttons didn't work no matter how much you touched them. There was a delay and the selection of movies and tv were pathetic. I will not be flying Qantas again.

Nothing, they didn’t care about you or to help, the llady was so rude and unfriendly, this situation ruin my whole trip

I call in advance to paid the fees for baggage, I call Aeromexico because was the main airline for the fly, but Delta at Seattle made me paid again the fees for baggage’s even by phone they said that I didn’t need to paid. BE AWARE AND CAREFUL BECAUSE THE LADIES IN THE FRONT DESK didn’t even look the paperwork that you have in hand, they only want to charge you saying that your payment thru Aeromexico didn’t help you in the 1st fly. How this can happen when Delta and Aeromexico are two subsidiary one of another ?

The people and the service were top notch. I fly on numerous carriers and overall AirNZ has been my favorite, hands down, primarily because of the helpful kind friendly staff.

Disembarking down onto the tarmac, and being made to stand out there for about 5 minutes (supposedly for safety's sake) while another plane was being pushed out from the next gate, all the while breathing in the choking nauseating jet exhaust fumes while our own plane was idling.

There was a lot of confusion for people trying to use the kiosks to check in. Finally a representative stood by the machine and told people not to bother, just queue up for the desk to get boarding passes and drop of luggage , which took for ever. Once on the plane the seats are very cramped.

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:

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.
