Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

The staff on the plane were attentive and friendly. The frustration with the cabin crew was that we were served second to special diet people. And, we were in economy section. The boarding staff was mediocre. Got scolded for requesting to sit with spouse on 14 hours long flight home. Was told they cannot break up families for us. Didn’t understand how we were denied sitting together as we are husband and wife. After many words of exchange, we were accommodated. Cleaning crew did a horrible job! Bathrooms were unsanitary or dirty from beginning of flight! Didn’t expect sparkling as its economy, but did except decent.

Headwind delayed our flight which wasn’t the airlines fault

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Food could have been better. Too many passengers getting up and down all the time.

Overall experience was good but what really impressed me the most was the care the flight attendants took of a sick passenger who was sitting in front of me. The flight attendants would come and check on her quite regularly providing her support and comfort. Brilliant service!

Only answered OK and poor as there was no entertainment and I didnt have any food

4.5 hr international flight. We got a glass of water. Ranks up there with Ryan Air, Easy Jet, Spirit and Frontier. Expected better.

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

Very good… seems the virgin staff particularly in the lounge and in flight exceeded expectations.

I liked everything about the experience but would have liked some free snacks!

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.

Being told why we delayed three hours and not even given an apology by someone. Not a word. Not my airline of choice ever.

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.
