This time is good . Don’t cancel flight with out early notice .

10.0 ExcellentAnonymous, Mar 2024BNE - MEL
Read more about Virgin Australia reviews

This time is good . Don’t cancel flight with out early notice .

Very good experience, considering the short flight the meals were served promptly after takeoff.

X class seats in row 3 with the new configuration are very poor in fact I feel 3B and 3E should no longer be considered as X class seat as there is no forward seat pocket available to these seats and greatly reduced leg room due the intrusion of the business class armrests/table module

It was pretty good. Everyone friendly. Like all airlines, the draconian limitations on baggage and weight and not giving even a free soda kind of drags down the experience a bit.

Last 10 minutes boarding they canceled the flight and didn’t organise anything

Estheticly the plane looks great, although the seats are way too upright. If the seats were just slightly more reclined then the comfort level would increase tenfold. I had the stiffest neck after just a short flight due to this. A nap was almost out of the question.

Cabin crew were very professional and welcoming. They certainly appeared to have lifted their game. Congratulations

I know not directly a Virgin "thing" but I hold Virgin responsible for their subcontractors. Had to wait 45 minutes waiting for baggage at PER before the belt conveyor even started. This is unacceptable and hopefully Virgin engages with whoever to pull their fingers out. I realise PER staff are generally slow at the best of times but this was ridiculous. Maybe more seating for those waiting, a cafe in the baggage area for a light meal while we wait or at the very least a troop of dancing girls to entertain the punters while they stare at the conveyor belt start light almost willing it to fire up.

Very poor. Flight was cancelled due to captain exceeding hours. Told to fend for ourselves for 12 hours until a new flight could be done. This meant overnight accommodation in Hobart. Next plane was delayed and no food onboard. No apologies from Virgin. Extremely disappointing.

Flight was cancelled due to a mechanical fault - Virgin rebooked me on a flight 6 hours later so I cancelled and flew with another carrier

There was nothing I didn’t like, prices a little lower would help

BA Airbus A380 BC upstairs had 2 3 2 layout. The seat was comfy but access for those in middle or window seats had to climb over others fest to get to ailse when seats in bed mode. The layout was not nearly as private as other layouts. The staff was amazing as well as the food. Most airline food is average but this was restaurant quality.

Following a marathon flight riddled by delays and changes from Santiago, Chile, my flight to Melbourne from Sydney was on schedule but I was transferred to the next flight. The reason by ticketing and the floor manager was I missed the entry to flight by one minute! That's right, the emphasised that if I was 1 minute earlier I would be on the flight. I asked what was the point them emphasising 1minute overdue and how that helped me or the situation. They didn't care at all. Replying that if it was one minute earlier they would've done something and smirking delivering the information. Australian's do call Australia home, Qantas calls Australian's suckers.

Qantas are unable to service and unfit for purpose, they cannot transport Australians on time to overseas destinations. On top of the inflated ticketing, the Sydney flight to Santiago was impacted because the plane was delayed arriving and then further bungling by Qantas admitting the ground new ground crew in charge of cleaning were not trained. The impact on passengers with connecting flights was tremendous and long ques of frustrated passengers waiting for rescheduling. **Qantas has become the Australian Spirit of disappointment**

I was pleasantly surprised with my flight to LA with Qantas. Although seats were not the roomies, service was excellent.

The service and smooth landing. Food was delicious and the staff was friendly. We arrived earlier than scheduled.

Wonderful crew, good food. Absolutely loved the wine spritz and wish I could buy it!

Don’t like last minute airline change. Not able to choose seat earlier.

Enjoyed the new possibilities of in flight entertainment. Been awhile since I've flown, and that was a nice surprise. Being able to pick from such a variety was personalized and welcomed.

It's only a short trip from Sydney to Melbourne, which i have done many times. The trip met my expectations

Surprisingly easy! I was hesitant to try this, but the cost swayed me. I actually felt like I had less stress than all the taxiing and possible delays that occur with short regional flights where you spend less time in the air than getting to and from the plane..

It was okay, no wifi or entertainment real disappointment. Staff onboard not very friendly.

This flight was delayed multiple times and eventually canceled around 2-3ish. Original take off time was around 10:30am. By 3, there were no other options out of Houston, so stuck in Houston for from 3pm - 11am the next day.

It started with multiple delays, cancellations, re booking, 5 hour lay over and finally on a plane from Chicago to Pittsburgh. Gates, times, etc were changed multiply times. Once on the plane, staff was fine, but built in tv did not work and could not even turn it off. Light at eye level the entire trip, so sleeping was near impossible. No snacks or drinks given.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Only water and pretzels served on six hour flight. Did not see crew rest of flight. No video screens and so no wired audio. Poor sound on plan so did not understand anything said by crew. This is a safety issue. Electrical socket did not retain charging block so could not charge phone. No video screen so could not watch movies. Phone is not a substitute.

It was fine. Flight was on time and arrived at destination with 15 min to spare.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

I paid $380 for my one-way ticket from California to Minnesota. The fair did not include online check-in. I received instructions from their app to check in at a kiosk. At the kiosk, the boarding pass would not print until an actual person came to verify that I had a personal item and not a carry-on item, On the plane, the person next to me was drunk and allowed to continue to order alcohol. United is garbage I’d rather fly spirit.

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

Even though we left CMI late, we mostly made up the time.

Delayed almost 4 hours for a 45 minute flight with no explanation.

Again, multiple delays and I eventually just canceled and drove!

Great crew. We were delayed so that late passengers could get on the flight. Love the bedding in business class. Good food. Great experience.

The CX617 from HK to BKK was delayed more than 1.5 hours.

Horrible - they lied to me about baggage & boarding, even though I specifically spoke to their agents the day before my flight about my issue. When I showed up they did not let me board and stranded me at my airport until I bought a new flight with money I did not have to spend.

All four American Airlines flights I took in last seven days were delayed. Caused me loads of problems, missed meetings, loss of time and money.

American cancelled our flight home. Zero option for hotel, alternative transportation and took 3 hours to find our bags so we could take a 3 hour UBER ride home on our dime. Never flying AA again.

They gave my seat away although it was a connecting flight with them and the flight was a bit delayed.

They ocer booked the connecting flight. My bags took a long time to come out, nevertheless I got to the gate in time to board, but they have given my seat to another passenger. They were aware I was connecting from another flight that was a little late, but they did not care. The customer representatives were rude. A horrible experience.

I liked the early check in. Flight was a bit bumpy due yo weather. Overall, everything went well.

Limited snack options cause the snack vendor was on strike

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

I was appalled to have to pay for just a regular seat when I went to book 24 hrs before my flight! Because it was only an hour flight I didn’t choose a seat from Grand Junction to Denver, but I did for Toronto and had to pay just to choose a regular available seat! In my 60+ years of flying this was the first time I have heard of this. Also, allowing people to bring on “huge “ suitcases, not carry on size, but much bigger, and then a large pack pack stuffed. So they take up all the room in the overhead bins and if we are later boarding, there is no room so we have to check our small carry on. I have already paid for and checked in one bag! I certainly will not choose to fly with United again unless it is the “only” airline available!

on demand entertainment in seat back awesome Check in Kiosk too demanding with endless demand for more information information then says go to counter. Counter agent unfriendly. Do it yourself check in luggage procedure not intuitive, upset employees frustrated the whole procedure.

It was an excellent experience, traveling from Toronto to Denver with United.

Ontime boarding. Almost 1 hour take off delay. We could have boarded slightly later since the pilots were in traffic

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

Fresh fuit or veg snacks would be so great, but there are two good restaurants in Denver airport. Try Etais UDIS or Freshens DIA for nutritious delicious pita sandwiches/ donairs and crepes in Freshens.

Crowded plane but it flew on time and had friendly staff
