The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.

The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀

Plenty of leg room, temperature was great and staff was excellent. Would do it more often.

Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.

Great. Very smooth. Plenty of information. However, wish they would give out a menu in advance of making a dinner choice like other international airlines. The flight attendant says chicken or pasta and there are details about ingredients or spices requiring the passenger to ask which requires the flight attendant to answer many times. So easy to solve this problem. P

All fine save for the abominable catering. Really gone downhill. We found it all inedible.

Late flight caused a missed connection, had to be put on a later international flight without my requested vegan meal.

Half the bathrooms assigned to economy were out of action

The crew members were great. The food was good. Entertainment was average - Could use a wider and better selections of movies and series.

Flight was cancelled after 3 1/2 hours. Support for rebooking was overwhelmed. Lost first class tickets and to fly economy.

Seats! The eternal problem in economy. They are like stones!!

Everything is good except the seats are tightened no rooms for the legs,

The plane's pilots, including the captain himself, thanked me for the flight. I know it's just marketing, but it was really nice to see these people. It's a great idea. Airplane food is never "good," but the entire crew and flight organization were top-notch. I really liked Delta, and I think I've traveled all over the world, and that was something new for me. Maybe even the old planes, the B767, but next time I have a choice, Delta will be my first choice. Thank you, a satisfied passenger :)

It was a great experience. The only thing I would have changed was that the bathrooms were never cleaned and they got very dirty.

It was an OK flight with below mediocre service by their flight attendants

Wasted a lot of time trying to find the CDG lounge - it was not next to the connecting flight gate like the Air France staff said.

The only reason the overall rating wasn't "excellent" was due to problems in claiming luggage. The bags are delivered to the main area (Cinta 35) for domestic passengers, but to a DIFFERENT ROOM for international arrivees. After waiting 30 minutes, someone (who didn't appear to be from Air France or the airport) told us to go to another area. There we found our bags, which appeared to have been awaiting us for a while. We had to go through a bag check before leaving the airport. If we had been alerted to this possibility, or better yet, been to go directly to Cinta 34, we could have eliminated quite a bit of waiting.

I did not get my baggage at my final destination..poor coordination with connecting flights with partner airlines (Saudi airways). Also the food was very mediocre.

Not great , just ok . I expected better food but it did not deliver . Flight staff was ok . The guy at the drop off bag counter was the only saving grace in this whole trip . He was pleasant, friendly and very helpful . You couldn’t ask for a better assistance from him .

Food could have been better especially the breakfast. Overall it was a good flight

Great staff great experience, made a 2 hour delay very bearable

I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼

Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.

Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.

Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,

Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.

The crew was very good. However, the equipment was a bit dated. Some of the electronics were not working. To top it, three bags didn’t arrive with me. Two of them were delivered a day later. I’m still waiting for the third bag, I was so looking forward to this virgin Atlantic flight, but, I am disappointed.

My only complaint is that the pocket in front of me was ripped and my things, like iPad and airline magazines, kept slipping to the floor.

Flight delayed yet again. Crew apathetic and unhelpful re affect on connecting flight.

I think Virgin is one of the best flying experiences, especially from/to the UK. The staff are so helpful and fun, the food is good, seats comfortable, goof entertainment and great value. Check in and boarding is pretty pain free. I also find that the other passengers are generally so kind and considerate than when I've flown other airlines.

The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Old plane, food not that great - lacked taste. Crew was nice but strict.

Terrible airlines, kept lying to me about the fact that my connection flight was cancelled. Left me hanging until last min. NEVER AGAIN

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Upon departing and landing, the man seating in front of me had his seat leaning back. Taking off nobody told him anything. Landing someone from the crew said something but the passenger ignored him and nobody followed up. Felt a bit unsecured. If this that is some of the basics are missed, what else was overlooked?

On time, reasonably comfortable for economy, decent food. All in all a very good experience.

Every flight got canceled or delayed. Customer service was awful.

Nothing to answer your questions appropriately. It was just a 2hrs flight from London Heathrow and we were served a cup of tea only. So the questions about food aren't relevant and also, there's no entertainment on these short haul flights. Overall, the flight ✈️ was okay.

SAS is very good at service, the lounge was great, and flights were on time. Boarding is fast and efficient!

Flight & service all top notch but online check-in a poor experience. Clearly a glitch on their website which prevented completion via my Android device. Also no easy way to provide this feedback to the airline so they can fix it!

Flight is delayed by more than an hour without any reason, the jet blue gates kept changing every 20 mins and there is no proper communication. No ear phones provided in flight, there is a screen with entertainment but what is the use, I have earphones but the console has outdated audio connections, no usb C or bluetooth, they are living 15 years behind

Horrible. Flight was cancelled, jet blue app not working to rebook, no phone number available to call Jet Blue, 400 ish people in line for the help desk, stuck in Boston for 2 more days had to book new flight with a different airline and still not sure if I will be able to get any refund.

Flight was cancelled, no support at JFK even though it is their main hub.. wait times on the phone was very long

I liked the punctuality, the crew, and overall the whole flight

Separated a pair of family members(father and teenage daughter) on all legs of the flight that were booked together, just to create an upsell. Food was horrible and only catered to vegetarians and gluten free crowd. I’d rather give more of my money to another straight shooting airline.

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

When I agreed to give up my two seats because of overbooking by the airline, I should have been offered some sort of reward or credit towards a future flight. I was not. It was not until the next day when I mentioned it to a Jet Blue employee that I was advised to call 1-800-JetBlue. So here I am, having done Jet Blue a favor and I had to do the work to find out if I was going to get a credit. Such service

The food took two hours to be delivered to my seat, when I'm on an overnight flight I want to sleep asap after take off

Flight was fine, price was good but food onboard was abysmal. I was on there for breakfast and lunch and dinner 845am EST to 845pm GMT and all I got was a yoghurt parfait, fruit and a piece of cake. Later snacks included an ice-cream brownie and a pizza twist. I was hungry by the time I landed and the airport amenities were closed. Not happy.

My TV was broken that was the only bad part. The rest was great.
