Flight was canceled in good weather due to mechanical issue. Rebooked to flight to different airport in area that landed 7 hours after initially planned arrival. We had to jump through hoops to get taxi reimbursement given flight landed in different airport at 12:45 am.

Flight was canceled in good weather due to mechanical issue. Rebooked to flight to different airport in area that landed 7 hours after initially planned arrival. We had to jump through hoops to get taxi reimbursement given flight landed in different airport at 12:45 am.

Flight delayed by over an hour…not their fault exactly, but it wasn’t convenient either. Other than that a great flight and STUCK the landing!

Great - i’ve been flying a budget Airlines for the last several times. And this was a breath of fresh air. Enjoy the atmosphere. The complementary drink and snacks, free carry-on. It was a breath of fresh air.

They cancelled the 6am flight around 12:30 AM the day before. I was luckily able to book through another airline. I called for a one way fare refund, the new flight is much more expensive. I lost $$$ in the difference and this caused lots of stress. I intend to take action following my trip, really off to a bad start and I will never fly Alaskan again

My travel mate needed wheel chair assistance getting on and off, and it was excellent. Thank you!

The flight was on time, seats were comfortable, crew is friendly and professional. Nice flight overall. Thanks!

The plane was delayed almost 3 hours. I had a first class seat and there was no food loaded due to the late night departure (no nuts, not meal and no cookie), and the first class bathroom was out of order. Truly a disappointment all around.

Over all it was great. My original flight was canceled but they quickly rebooked me. I was frustrated because I had to cancel my entire plans for the day but all considered, not bad. The crew tried to keep us calm while we sat in the plane for was felt was an hour or so but they could use a bit of a script. The seats were comfortable and I would give it another try.

Having the internet available while flying was great. Better than having to choose from watching movies from a limited selection.

Not able to get boarding pass for domestic connection flight when check in at international airport. I was told I need to get connection flight boarding pass after I entered US. It us very inconvenient.

There were no food or entertainment on this short flight. Friendly staff even before getting on the flight. The seats were snug but it was quick flight

Very friendly staff. No food service and no entertainment. Only 1hr 20min flight

Flight was late, food and drink an extra charge, my carry on is five rows behind me, and the seats are too narrow. Don’t ask me to be happy about it

It was with Link Airways and the Saab 340 jet was noisy and little comfort.

Gluten free options less explicit on business class, but great service

Crew was great but flight was delayed almost three hours due to a technical issue and we had to go back to the terminal and wait for another one.

Virgin has always provided a smooth and comfortable flight. This one was no different. Seats are comfortable. Staff are great. This is my favourite airline.

Check-in was good and efficient, Boarding was quick and easy. Didn't like the entertainment side of things requiring your phone to connect for a screen, my eyes are bad enough to use my phone more than I already do. Trip was comfortable and baggage claim was good. If coffee and tea were free, then why not a soda or juice as well, its not like its an alcoholic drink.

The flight was delayed by 45 minutes, but boarding, actual flight, and crew were great. However, there was Zero free food and only water, tea, or coffee to drink. Everything else was for sale. No onboard entertainment but it was a short flight.

I'll never transit from international through Sydney with Virgin until they improve the domestic transfer system. It's ridiculous that you have to take oversize baggage to the transfer desk to get it activated then struggle onto the shuttle bus (carrying a 25kg, 2m long ski bag and carry-on - along with about 6 others in the same situation) then negotiate the terminal and queue to put it onto the oversize receival bag drop.

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

Uncomfortable plastic seats even in premium economy. No free wifi. Even paid wifi was spotty to nonexistent. Bad food. Much worse than economy on foreign carriers like Qantas.

It was good but only meal served is very less. Meantime good to add rice and chicken in one of meal

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

Horrific. They missed my connecting flight to San Diego. I didn’t get there until Monday at 9am when I had a mandatory court settlement conference scheduled at 6am since we had parties on the east coast. This caused many issues. All because United apparently forgot to hold the doors open until my flight landed that only had a 10 minute delay. This was the last flight to Southern California. So I couldn’t even rent a car to finish the trip. United cannot be trusted when traveling on specific days and times since weather didn’t have anything to do with the delays.

Great. Food going from Australia to the US was better than other way around, but still needs improvement in terms of quality and quantity!!!

Was a pain having to leave the plane and reboard but glad the plane was fixed

Connecting flights were poor,especially in Naples.our Lufthansa air bus was a joke.way too small for that long of a flight.no room at all.couldn’t even get out of the seats to move around or go to the bathrooms.we thought we were getting an actual air bus,double decker.i will never fly that long in a plane like that again.kind of misleading to call it an air bus.we actually had more room on our buses that we used.

Due to a cancelled flight the day before this flight only had 44 people. Best flight ever on international route. Food getting better. Can United provide fruit ex apples and bananas for snacks? Crew fantastic.

Nice crew - very small plane and uncomfortable, with no entertainment options…

We were given an upgrade which provided more seat room and a meal. However seat designated overhead locker space was used by others.Boarding was delayed with part or the delay due to staff assisting diaablef individuals aboard. Personal observation would suggest that 3 individuals rorted the system. They used wheel chair access to the plane, boarding with family ahead of al other passengers, but required no assistance until boarding occurred. On departure 3 “disabled” individuals were seen walking freely near the baggage carousel. One person even assisted with a luggage trolley! The rorting is most likely widespread and not airline specific

Not good with Kayak … There is no customer service number to call ?? We have stuck at Toronto airport but air Canada don’t help because we bought tickets thru Kayak .. Kayak should have customer service number listed for help .. Very bad .. we will think twice to buy the tickets thru Kayak next time.. Ahluwalia

We paid $110 for more leg room. My traveling companion’s knees were right up against the seat in front. Where was more leg room. We feel ripped off. Food,,,there wasn’t any not even a bag of pretzels. As a result, there was very little service.

A 6 hour flt and only offered water twice the entire flight. A small bag of flavored pretzels was offered as well w/ the first round of beverages. The landing was ‘hot’ but I arrived safely. The plane was nice and new and the seats were roomie. I’m use to warmer more generous hospitality but all and all I’d fly with them again but I’d bring more water and snacks.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!

Air Canada didn't properly check the maintenance status of the plane prior to boarding it's passengers on to the plane. A final check before liftoff and we had to switch planes because of mechanical flaps issue.

The entertainment system is very slow. Scrolling through selections is slow.

The food and service were great! The flight was on time and comfortable.
