Checked Baggage line up was long but moved quickly, rest of the process, boarding, crew was excellent

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.

Virgin changed the flight to an Alliance flight. Smaller plane, tea coffee and water the only refreshments available and not sure what happened to the extra money I paid to sit in a selected seat with extra leg room. This is obviously a regular switch as it happened on our flight there and back. Do not recommend.

Late boarding, late departure due to weather and slow boarding, packed 5+hour flight, only 2 toilets for main cabin, tight leg room, no free food except tea, coffee, and water, arrived 75 minutes late.

Cramped, crowded flight, with no complimentary food except coffee, tea, or water.

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.

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.

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.

Boarding was smooth after a 25 min delay. Notification of delay could be more efficient and change in boarding gate was not notified on the flights board or app.

Excellent. Shelley was very attentive and caring regarding my sister who required pre approved oxygen during the flight. Shelley checked up on her regularly throughout the flight and made her feel more relaxed and comfortable.

American Airlines was their usual junk service — but at least it got us down to LA. I was more irritated that while they codeshare with Alaska Airlines in Seattle, they could not out our flight on one of these, opting for one of the small SkyWest operated American Eagle flights — and causing a 14 hour layover. Which I accepted due to a $2000 difference in airfare — that said it was irritating for a flight that usually would have cost around $100 extra, if that.

nothing to complain about w/the food, and professionalism of the crew. i just cant stand being on a flight for that long of a time.

Everything was great from the staff to the seats and food. The plane was timely taking off and landing.. I couldn't have asked for a better experience (especially on such a long flight)

Good communication regarding any updates time of flight and flight delayed. The fight was delayed by two and half hours at eleventh hour. That was unexpected, especially when you international passenger.

The service was excellent. The quarters were a little cramped in Economy, and we had to exist there for 18 hours.

It was very nice. I will try to fly with Qantas whenever I can.

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

We lucked out. The passenger who was supposed to be in our row changed her seat, so my husband and I had 3 seats for the 2 of us. We were able to stretch out a little which made the trip much more tolerable.

We paid for business class seats for the comfort that comes with that but couldn’t use the bathroom as it was full all the time.

Flight was cancelled about 1.5 hours before departure. Replacement flight provided scheduled 1 hour later. Late boarding, late departure and arrived Melbourne nearly 2 hours after originally scheduled.

We arrived early and finally made it to our gate almost an hour after.

The reason I don’t fly United. No in seat entertainment for a long flight and inconsistent WiFi and entertainment available from my device.

We were delayed 3x and because I didn’t purchase my tickets directly from United Airlines I was told I Have to take care of it myself so I called Underpricer and they helped me but before I changed my flights I took the risk of sticking by what my tickets were and was lucky to have gotten on the original all flight with only 15 mins before take off. not sure if I will do this again

The flight was delayed so the people from a late connecting flight was able to still make the connection.

HORRIBLE WITH THEIR WEBSITE!!! WORST WEBSITE IN THE WHOLE AIRLINE INDUSTRY

The planes are so dirty! Food crumbs and finger print smudges, Dust over the vents and carpet stains. It’s disgusting.

Everything good until we waited for jet bridge at SFO. Then pilot gets on speaker & said it won’t reach plane- too short, need to go to different gate. Then 5 min later, adjusted plane/jetbridge & all ok?!?

Gate got changed about 4 times. Very confusing and very crowded. If you don’t have wifi to help get updates, you can be in deep trouble.

Did not even get on board. Was told I needed an esta agreement. Was not aware of this when I booked the fare and not told about them

David went above and beyond to make our flight the best that it could be

Other than being delayed 5.5 hours and having to get a hotel because I missed my connecting flight, it was an okay flight. No in-flight Wi-Fi or entertainment.

Flight areas delayed 3 hours , train in the airport didn’t work

Flight attendant walked away once they landed and we were forced to wait another hour after an already 3hr delay.

No overhead space so all carryons were checked. No internet.

The flight was on time and everything went very smoothly.

A thousand choices for movies and nothing to watch. I avoid 'R' rated shows and others with violence and sexual content, which results in a handful of flicks to view and I have them already.

I think I paid for an extra legroom seat and to be honest, there was not a lot of space available for my not very long legs. The flight was totally full and the staff did everything possible to meet the needs of all passengers. My only concern was for the size and spacing of my seat.

Flight was on time Crew was not. very friendly I paid for premium class and It wasn’t too much different from coach

Two issues. The plane was old and dirty. The armrest looked like an old car that had the vinyl rubbed off. The Seats in these aircraft are about as hard and uncomfortable. I want to tour Italy for a month and I want to buy a one-way ticket to Thailand but I will not sit in the seats these planes have. It is seriously stupid how hard they are.

The meals were mediocre and the alcohol selection was poor. I enjoyed the selection of movies and other entertainment.

Service was excellent, but they ran out of food options by the time they got to my seat (row 36).

The idea of needing to go outside in the winter to board in icy cold temperatures is totally a non starter for me. Seats were very uncomfortable though the leg room not too terrible. Attendants were nice

The experience was good. Flight was on time. Liked how they offered to accept carryon baggage for free before as I was checking in online.

3 hours late departure with no explanation. $160 luggage fee (two passengers) for less than 1 hour in the air!

Flight was delayed by 45 min. No problems. Everyone took it in stride.

Crew was friendly and helpful; cabin seemed roomy even in economy class.

The flight attendants that assisted me were exceptionally nice, kind and helpful

Something wrong with the plane so had to deplane and waited over 2 hours to finally leave

AC needs to update their fleet. Too many mechanical issues, dated planes and too many delays

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.
