Drink lots of water. Sleep to the destination time, not the original time and clean up after yourselves - the flight staff are already working hard, they should not have to clean up after adults.

Smooth sailing trip, pilots are good. Less amount of food offered but the quality is okey.

Kayak uses scammer sites to steal money from their victims.

When one asks for water because they are dehydrated, bring more then a sip or two in a small cup. Bring them a whole bottle.

Food could be better it was okay. Entertainment seems dated it was something but in this day and age could be a lot better.

Very clean ,flight attendants very professional,nice , Boarding was very easy

The aircraft was massive (A-380) and became crowded with 400+ passengers on board.

Coming back to America was a peaceful flight everyone and everything was perfect

Staff always with a smile and very helpful with my mom who has mobility issues.

It was all perfect and very pleasant for such long flights

The crew was amazing and really nice. The OS on the entertainment system could use an update, though. It felt old and outdated but had anything you'd need to keep busy. I usually never use it anyways, but that did stand out.

Check in at the desk was very slow pus Security, although not Virgin issue at JFK was a nightmare. 50 minuet wait no time to explore airport and get last minuet gifts. total wait 1.5hours

Food has been disappointing in both legs of flight to india

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.

Great crew - old style upper class seats on the older fleet now feels dated

The crew was excellent as ever on Virgin. The special meal was poor unfortunately. More significantly when we arrived at Manchester Airport there was no air bridge provided and we had to exit the plane down a rickety stair case. This is unacceptable for a transatlantic flight. Whilst I understand that this is the airport’s fault at the end of the day the airline is responsible for our transportation and needs to do something.

Super friendly and helpful staff, from check-in desk to cabin crew.

Following a paid seat upgrade for enhanced comfort, I encountered an unacceptable odor in my assigned area. It took three hours for the crew to relocate me, and the replacement seat was unacceptably close to the lavatory, offering no improvement.

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.

Weren’t even given earphones to use the entertainment system

On time. Friendly and helpful flight attendants. The plane was clean. Having a wine available would have been nice.

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

Nothing to complain of, the only reason I am not giving better marks is that I am used to flying with ANA and they are the top.

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

The ticket was last minute buy so no concerns about the pricing this time, but the crew in general could have been more accommodating, helpful.

Food no variations only beef of chicken no veggie meals

Excellent experience however older aeroplanes used by China Eastern Airlines.

I was surprised and appreciate that they actually served a hot meal on such a short, early morning flight. The check in and boarding was hassle free and most of all my Alliance Status / Code Share was recognized and the revelant courtesy was extended; other than some needed attention to detail concerning the cleanliness of the cabin, and some unnecessary aggressive wording their safety briefing, it was an overall pleasant flight, and I would certainly fly with them again.

For the price we paid, we had a really good flight. The seats and bed (business class) was extremely comfortable. I have no complaints. The crew were very attentive and helpful. They spoke English and there were no misunderstanding although their English wasn’t perfect or fluent. You will never go hungry as there was ample food and drinks but their food for mediocre. The entertainment was limited to older movies and the wifi didn’t allow you to access some Social media. Apart from the above, it was a very pleasant flight. Would highly recommend them.

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

We were cutting it close on our connecting flight and notified all staff at departing gate and flight attendants. From the start, we were told to check in with the international transfer desk by everyone, except for one lady who wanted to argue the time difference that was already taken into account. We also asked if we could try to exit the plane first (our family of 4 and 8 others on the same connecting flight). They just told us to check in with international transfers. We landed and had very little time to make our next flight. We were not offered any assistance or communication to the receiving gate. We ran all the way to the international transfers gate only to be turned away. I think we could have made it if we were allowed to exit and a call was made to other check in counter. After that we spent 6 grueling hours with our kids trying to rebook a flight. No food of any type of compensation was offered besides a dirty hotel room. The ladies with China Eastern at the Shanghai International counter were rude an unhelpful. We were directed to 3 different counters and waited before they said they forgot about a hotel. It was a long, miserable day. I believe this could have all been avoided.

You’re in the three parts of my life, the China Eastern air crew remembered and wish me happy birthday. I was given pastries on two different occasions and a complementary drink. The stew is wish me happy birthday and gave me a birthday card. Everything was first class. Thank you.

It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-

I will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.

Flights were delayed and due to a checked hand luggage bag by an overzealous gate agent in Berlin I missed my ground connection costing me another £80. Food was cold and bland, I honestly expect better from a national carrier operating out of one of their major hubs.

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Missed our flight to London and we were put on coach seats to Munich.

Seats were terribly uncomfortable! Couldn’t sleep! I paid for good seats when scheduled with Lufthansa, got crappy mid-section seats on Air Canada!

No refreshments apart from a bottle of water. No pillows. No entertainment. Flight delayed by 52 minutes.

The seats are much too narrow and the arm rests are hard and awkwardly high, resulting in shoulder cramps. I am an average sized person ( definitely not overweight). The seats are a similar size to car seats with the added discomfort of incorporating hard plastic arm rests, that force average height individuals (I'm 5 ft 7 (f)) to hold their arms uncomfortably for several hours. The seats are much too close to the ones in front and behind making it extremely difficult to allow fellow passengers to get out, especially when the seat in front is declined. The leg room also necessitates knees banging into passengers backs for the entire flight. This used to be a quality airline who now offer mediocre service for premium cost, coupled with charging exorbitant prices for basic needs, like a seat, or luggage. Blatant and unabashed gouging of clients.

Another 35 min delay landing No apology no communication or acknowledgment about this

Try to humanize onboarding and take AI out. It's embarrassing and useless

Another excellent flight and overall experience with Lufthansa. Long flight in a wonderful ambience. Thank you to our outstanding crew.
