they had to land at Dulles instead of EWR and had no one to help all of the stranded travellers the crew was rude and not helpful as well

The layovers / connections were too short and too long. I SPRINTED to make the connection from OSL-JFK and then SAT for over 6 hours from JFK-BUF. I don’t mind a longer layover more than I want to RUN to make my next connection

Our vacation started with horribly, 48hr prior to departure SAS airline cancelled our return flight giving us little to no alternative options.

The layover was very long. Other than that, great trip so far

Elderly traveler with disability was bumped from extra legroom to economy with little legroom. He couldn’t bend his knee to fit in the seat. Very uncomfortable for a 7 hour flight and will be reported to DOT. Then the food was disgusting. Boiled chicken with boiled rice and steamed veggies. 3 slices of carrot and one broccoli. We couldn’t eat it. No salt or pepper provided. Disgusting.

Payed $140 xtra for seat arrangement Did not get the preselected seats neiter outbound nor inbound. Absolutely not worth the xtra money

Gate agent in Atlanta refused to let me take my carry-on on the plane even though I met weight and size requirements and the plane was half empty. My ticket clearly stated that I was entitled to one carry-on and one personal item. Will not fly this airline again.

Flee premium economy. Very comfortable absolutely a better seat more recline, wider, and more legroom. Flew Business, which was lie flat comfortable with decent food. In P E Basically the screens audio hardly works and the selection although 90% in English is very limited. Wi-Fi did not work both ways across the Atlantic. It was “broken“ very efficient operation. The app was great. Notification is fine. It was just the entertainment and the food in premium economy was lousy airline food. But yes, I would fly them again in PE or business if they were going my way.

not good missed my connection SAS did not leave me anywhere near enough time to make my connection. Ended up adding about 10 hours to my travel day

Boarding was chaotic and the flight left late but arrived at a decent time. This may have been because of the sxsw festival that was going on.

Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

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

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

The crew should demonstrate flexibility by moving a screaming infant to its own seat with 1 parent

If I could fly Virgin Atlantic airlines to every place, I need to go, I would. Leaving Heathrow through the special virgin air entrance, security is completely white glove service. I love this airline. From ticketing agents to flight staff everyone tries to make it a wonderful & happy flight experience. I wish other airlines copied the positive culture of Virgin Airlines.

The thing thy call a pizza was atrocious. Do not eat it. The seating is as usual for economy an experiment in cruel and unusual punishment that they aren't allowed to do to prisoners but you get to pay for it.

Didn't make it to this flight as we sat on the tarmac for 1.5 hours.

The crew was first rate. They allowed me to switch my middle seat to an isle seat and it made my flight home so much more comfortable.

Everything went very smoothly I loved having the earphones and the blanket and the staff was just super friendly

We traveled with my 90 year old mother and she was well cared for by everyone from the wheelchair attendant to crew. Greatly appreciated!

The free WiFi was great so I could stream movies during the flight. I would like to have movies available instead of on my device. Thanks!

I was pleasantly surprised and enjoyed the services of the airline since flying is not my favorite thing. My goal was to be with my brother's family in Manchester after his death. All staff was helpful, the food appreciated since I selected an overnight flight. Every aspect of the experience was comforting. I plan to return to Manchester in order to attend my brother's funeral in October and hope that I am able to find a reasonable priced flight. Thank you

Very good except for the boarding process which was more hectic than it should have been

I would definitely use a Linus again, the price was right, the service is excellent. No delays. Wish I had a direct flight from my hometown Detroit.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

I like crew. They are friendly. The flight was delayed to take off for 1hr and that caused panic at Houston Airport to catch connecting flight due to security check delay. If it has reached on time I would have sufficient time in collecting bags and security check

I hated the FRA Airport. Confusing signage, including the path to Immigration and Security It seems that the airport grew haphazardly over the years. I have been through multiple WW Hubs with much better experiences.

The seating arrangement by having privacy screens would have been more appealing. If you sit in the business class, you pay for extra comfort and privacy. Other than that, the service was excellent and the staff very professional.

Great experience. Flight was on time and reached destination on time

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

I had handicap and pre board due to a recent broken arm, was made to find my own help placing carry on baggage in the storage above. My tv and entertainment unit did not work correctly, requested help and it took 30 minutes to get help, she did not fix it or come back to see if it was fixed. I went to her a second time and she did another reset, still did not fix.

Did not fly HOU to SAT as flight was cancelled.

Had a plane! Have a plan! Have my luggage! 10 hours of travel turned into 50 hours. Good Lord!

God food! Although some of the snacks were not to my taste. Nice amenities in premium economy made for a comfortable flight. The pilot was able to make up about half the time we were delayed in the ground (we were delayed over an hour before takeoff due to a shortage of tugs) Nice movie selection for entertainment. We were last to board the second leg of our flight due to.complications during transfer from the first flight of our trip, but did manage to board in time. We really enjoyed the video presentation for flight safety. Hilarious gets your attention! Really nice, sufficient accommodations for overhead storage, didn't seem crowded or jam packed. I enjoyed being able to track the flight on my monitor. I was disappointed that there wasn't free WiFi during the flight, I thought that was a complimentary service but you had to pay extra. It felt like we were nickled and dimed on that one.

Very comfortable flight and simple and directed one way and back. Amazing price.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

food options were terrible. for a 10-hour flight, there should be 2 decent meals. Also, flight attendants should come around with drinks more than just at the meals.

Good. For a long flight. The comfort of the seat could be better. Also, the food was « normal » plane food. Not indian plane food unfortunately! Everything else was smooth and great.

My seat cushion was poor. The cushion was compressed and was uncomfortable for such a long flight.

There might be more food options for people who can't eat so much starch/sugar/bread/rice. Meat, cheese, walnuts/pecans for snack, maybe jerky or other kinds of meat-based snacks would be better than bread and rice and sweets. I had an extra chardonnay, which was fine. The entertainment was great.

what would have been better would have been that my booking not been canceled by the system and had I been informed that the booking had been cancelled by the system I could have immediately rebooked and not found out that there was an issue when I was told by the system that I needed to book in. It would have also been good if either the booking agent or BA or anyone been in anyway useful. In the end I had to rebook a flight at an additional cost of $350. So no I'm not impressed by BA any of the other parties involved.

Flight was delayed but my previous flight was as well so It worked to my advantage. This was my first time in first class. I don't think they ever stopped feeding us. The seating area was very spacious and comfortable. The attendants were wonderful, warm, friendly and very personable.
