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.

Cabin crew on our flight showed lack of any customer service gruff and acting annoyed if you asked anything and I mean anything Example a man on the seat over dropped his beer on my husbands blanket We asked if we could switch out blankets cabin crew Said. No we don’t have any extras OK well can you take the wet one Cabin crew looked disgusted and annoyed Took it no OK or yes just a growl

Quick flight. But cabin crew were very noisy and talking too much, especially when we were seated at the back of the plane trying to sleep through the night .

My ticket was for Premium Economy and all the seats were taken, I was placed in Economy class and I’m looking for a refund.

Unfortunately delayed 2 hrs due to faulty tyre.. which had to be changed, but better safe than sorry.

The delay was an issue. Other than that. Every thing good

Hi vergin Atlantic service was good but the flight ticket agent travel up charge me extra 57 pounds as a airport charges, actually I refuse to pay but they say if I not pay £57 then they say you will not be able to travel from Heathrow to goa ,so for me there was no option and it was just 3 day before my departure so i paid, so please look in to the matter. And I have a receipt of £ 57 as well .thanks

Staff didn’t check cabin well for landing seemed more interested in chatting to each other. Food was poor and differed from pre order.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

Comfortable as it can be for a basic economy seat. The TV screen on my 15 hour international flight went out after 1 hour or so and it never worked again. The food is very high in processed carbs and sugary items.

A three (3) hour flight should have meal service in First Class, not just potato chips!

We had a 90 minute delay due to equipment failure that was detected just before we took off. United rebooked my connecting flight.

Everything was perfect except the pad at the top of the seat back. It pushes my head forward into a very uncomfortable position and it is not removable.

Boarding in Paris was a nightmare for us. Why passengers have to get checked luggage tickets and then to go to counter to get luggage weight and send to the conveyor? We counted 14 security and airline checks before getting in the plane. We will never again use United or travel to France, neither stop by IAD airport.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

Ridiculously slow disorganized boarding, ended up 35 min late and people missed connections

Really solid flight! The in-flight entertainment screens are not very touch-responsive in the way that of other airlines’ are, which was my only issue. But otherwise we had good food and drink offerings and the flight attendants were very welcoming.

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

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

Boarding and crew was great. Flight was cold, need layers. Deplaning was hard. We had to take stairs off the plane and I was separated from my travel companion because we were not seated together and they would not let him wait for me to get off so we were forced onto different shuttles.

Check in and boarding was easy, crew was cheerful. Not much to read or do on the plane and our neighboring passengers were talking loudly so we could not sleep. But overall good. Great coffee.

Flyplay is the only way I travel to Europe. Had a 15 hr layover in Iceland. Normally this would suck, but I regret a car and saw the black sand beaches, several waterfalls and sky lagoon. And finished with lamb at cafe Loki.

did not get the seats we had specially paid for

This is a no frills airline. You cant expect much for the price. Low cost flight, clean, nice staff. That's all I need for the price. If you want more, book with another airline and pay more. For Europe trips, PLAY is the ONLY airline I use

Misleading instructions for check in. Although I did virtual check in and was instructed to head to security, once I was at security, they told me to go back to Play ticket counter and get paper tickets. Also, beware that Play doesn’t participate in TSA PreCheck. I didn’t know that, despite entering PreCheck info when I purchased the tickets. I wasted time in the TSA PreCheck line as well. So we had two setbacks at check in.

Amazing! The food was great! Best airline meal ever. The crew was so nice and pleasant.

The plane was crowded, seats narrow, legroom practically nonexistent. The entertainment feature didn't work for my row and nobody was able to/interested in trying to fix it. This was a direct contrast to a very comfortable Lufthansa flight I'd taken from RDU to Frankfurt about a week earlier.

Connection time and departure time were both changed to cause undue stree on older people who cant run through an airport

The plane was 3 hours late. What more can I say?!.. This, plus my horrendous experience of the second leg of my trip in where the plane had to be boarded (off and on) without escalators.. but not-covered outside regular steps…!! No… this is my last flight with Lufthansa!! Never again!

We were delayed so long that I missed the next flight. I should’ve arrived in Catania at 4 o’clock and arrived at 1 AM. The late departure was due to a water leak due to a dirty filter, according to the flight staff, and that seems like something that should’ve been taken care of before the flight. It’s too simple of a mechanical problem to make you miss the whole day.

Paid for aisle seat and got a middle seat in back. One of the more uncomfortable flights I have been on. Impossible to get a refund.

Problems checking in. Charged for bag which was to be included. Repeated trials with in line check in process

Flight from Washington to Munich it was disappointing. I do not get the seat for what i pay. And the crew were rude with people which speaks other languages than german!

Delay before takeoff, ran out of protein options for the meal served, waited on the tarmac upon landing for and hour, waited in corridor for people mover for 45 minutes and still waited at baggage claim for over 30 minutes. This was after Lufthansa cancelled our flight to Frankfurt. Will definitely be my last option when booking overseas flights.

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.

Boarding is not controlled as groups called was not enforced

The plane was clean. The crew were lovely. Food was good - but seat 1D is a poor location. - the crews cupboard is right near your feet and they visited them frequently swishing the curtain from the galley onto my feet everytime also creating a swish of cold air each time & then slamming the door.

Horrible food and uncomfortable plane. One toilet was out of service.

Business class is fantastic! Lie flat seats, great meals, privacy, and lots of nice amenities!

Flight to Seattle was fine. We were delayed getting into our gate. The connection time was short and they make you go through security again which was slow.

The crew was great, the food was great, the seats were torture. I just could not get comfortable. Too narrow, too close to the seat in front. I felt guilty about reclining my seat and resisted but the people in front of me did not feel the same way. I thought both coming and going that the discomfort would conceivably be enough to prevent me from going abroad in the future. Will it? I'm not sure - but it will definitely be a factor in my choice of travel.
