The entire process was excellent! The economy sits are a bit snug so I'll have to be sure to purchase premier or business class next time but, other than that, food, service, attendants were exceptional. Gate agents and ticket agents too!

Short flight so no entertainment, turbulence so no food service - overall flight as expected

All was good, the only thing was it didn't run on time.

The staff and crew on board were excellent. Business class however, was very weird. I thought we would have individual pods, but the way it was set up was unexpected. Not very private and If you wanted to lay down, you had to have an entire bed made up for you by the crew, rather than how Delta one works where you could just lie down whenever you feel like it. It was a 16 hour flight. I chose not to have my bed made, and that turned out to be a good idea because everybody who had their bed made had to wait for the crew to roll up their mattresses. So strange!

Food was not good. We asked for Muslim food and it was weird tasteless type of boiled veges.

Crew were pleasant, happy to be there and were a joy to be around. Entire operation was professional, well thought out and ran like a Swiss clock.

Couldn’t request a vegan meal somehow but I noticed other people getting them

They announced food service but then never came around. We also couldn’t land so kept trying to get to runway and then had to come up and go around happened like 3 times and cause the child next to me to start throwing up

Good food and entertainment options. Great Staff that were all welcoming and caregiving.

The recline on the seat in front of me came back so that I was staring at the top of the man’s head in front of me the whole trip. He refused to bring his seat back up twice every time he was instructed to do so and only relented when he had a tray of good in front of him. And then right back in my lap!!! Horrible man!! I complained to the staff multiple times, but no one would address the issue. Otherwise, it would have been a perfect flight.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Do I need to repeat my complaints about my lost carry on bag?

Noice cancelling headphones would be better since it’s a crowded plane And kids behaviors are unavoidable

More facilities to transport to the gates......felt too much walking distance

Just happy I flew Qatar Airways awesome no wonder they are #1 in the world right now! The food was just delicious, very courteous, professional crew.

It was good no problems made it on time for the next flight overseas!

It was a really long flight from Doha to Philadelphia and it was overall a good one. The one area that I would comment on is that there is a lot of single-use plastic and disposables in the meal service for American Airlines. It would be great to see more circular options in the meal service to reduce the amount of waste.

Suddenly Flight has been change by Qatar and there’s no information is there of us from Bom to Doha and counter person is behaving like Qatar owner next I will not buy Qatar and I will not suggest anyone to fly in Qatar

The crew was fantastic and the over flight was perfect as well.

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.

For a red eye flight it is pretty uncomfortable. They provide nothing in the way of pillows, etc.

2 hrs + delay! Times kept changing, Onboard menu was half depleted, Entertainment wifi was N/A Overall very frustrating flight and I never slate Virgin.

Virgin Australia passed this flight onto Alliance, so my rating and comments are based on my experience with crew, aircraft and available options. Alliance only offers drinks which consisted of tea, coffee and water, free of charge. There was no on board entertainment. The aircraft seating although narrow accommodated my 6 foot 2 body with little discomfort.

When the flight is full out would be good to allow the use of the front toilet as well as the rear. Otherwise it was an uneventful flight.

When I made the booking I was not aware I had to book our checked baggage separately. As we had no checked luggage booking, I had to pay A$120 per bag (total 2 bags) so you can imagine I was not pleased. I am an experienced traveller so something needs to be done to improve the booking app,

Toasties not available (only GF option). Hot drinks not able to be served No usb charging port

Flight departed in time and arrived on time, no issues at all.

Boarding took place at the front and back. Weight of luggage was unclear and cost an arm and a leg.

The flight between Canberra and Coolongatta passed very quickly and was comfortable. The crew were very efficient and helpful. The boarding process is a bit slow and not done by rows. Overall, Virgin does a fairly good job.

Left late after one day delay. Even after we were called to board we stood in line for 30 minutes. Seemed disorganized.

They opened my checked bag and even though my lock was tsa approved, they loose my lock and left my bag just like that. Incompetent people, very upset about it. I’ll try to avoid traveling with united

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

Luggage management is poor, my missing luggage is still lingering.

Short and everyone communicated with me about the changes every step of the way.

Crew was good. Check-in and boarding was terrible. Family wasn’t seated together. Online check-in wasn’t available.

Airline staff was good the checkin process was ok but the plane itself was very bad the comfort was worst it was worst and the most stiff 5 hours of my life i felt claustrophobic

Flight got canceled after a 2 hr delay followed by the to crew timing out. No help with hotels, crew were rude, only help was via an online chat. Got rebooked for a non-direct flight 48hrs later. They could not have cared less regarding how this could create a medical emergency. They refused to give us access to our luggage because it was stuck in their transit area and had to remain their to be loaded on our next flight…so we have the clothes we have in and nothing else. They told us to “go buy clothes” ignoring the fact that Munich shops are all closed on Sunday. We were told we could get refunded for our expenses BUT one crew member told us it would be wise to spend as little as possible as it will “take forever to get your money returned”. I’ll never fly them again.

We left 3 hours late. Of 4 flights on my trip, 3 left at least 3 hours late and one flight was canceled

Brutal as can be … delayed by 24 hours then delayed and hour on the tarmac then delayed three hours in Chicago, screaming child behind me kicking the seat for the better part of 10 hours… couldn’t be worse

United did not permit online check-in from home as document scans were not getting uploaded. This should be fixed their app

Cancelled flight had to fight for a hotel voucher and lost my upgrade. Not great business.

Our flight was delayed by almost 1 hour, and this negatively impacted our experience. Everything else was OK.

dont advertise liquor drinks you don't have. begin flight on time. instead of an hour LATE. OVERHEAD BINS ARE TOO SMALL TO FIT STANDARD CARRY ONS

Ok, a very small soda in a small glass was all that was served. Pitiful. Comfort seat was not, no legroom at all would not recommend comfort class, not worth the extra.

terrible delay then had to change planes then delay again

Flying Air Canada was pleasant and enjoyable. The United portion was lacking.

we missed the flight because the preceding one was late. air canada said that because it was caused by air traffic control they would not put us up in a hotel, so since the next flight we could get anywhere near where we live is to san francisco tomorrow morning, two senior citizens are having to spend tonight in the food court at vancouver airport. NOT HAPPY.

5 day of cancellations and errors. Several days due to weather and several due to broken planes. Nightmare

The baggage handlers at Toronto did not load anyone's baggage onto the jet. We sat at the carousel in Pittsburgh for a half hour before anyone told us.
