Airline reviews

The Premium economy class is not the same as some other airlines because there are no economy seats on these planes. Basically you’re getting an economy seat that’s a little wider. The seats are not that much more comfortable. The service and food experience is similar to economy class on other Asian airlines. There aren’t enough toilets for the entire plane therefore we are forced to share the business class toilets that are closed off with curtains.

Good flight. The food was served a bit late, hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

I commend the flight attendants on our SFO-SIN flight who went above and beyond to provide us with extra snacks and food. This type of service makes the flight experience personal and awesome.

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

They close their counter so early. I had internet issues so I couldn’t check In online . I would have made the flight but their counter was closed 5 minutes before we arrived. No way of contacting them even though I had the confirmation number and tried to check in the night before on someone else’s phone. I tried calling their customer service with no pick up. Horrible experience, I’m very unhappy with them. I hope to never fly with them ever again. It costed me almost $900.

Transfer within the same terminal and lots of facilities at the airport.

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

Nice selection of movies and TV shows. Plane was generally nice, not the newest but nice nonetheless. However, Emirates should have cancelled the flight, as hardly any flights flew out of Dubai at the time. Flight delays and cancellation was poorly communicated and passengers were left guessing and to their own devices on what to do. Connection desks were staffed too thinly, there was one desk with more than a hundred clients and just one poor lady. When I had my flights rebooked, I was told meal vouchers can be scanned using my boarding pass, nope. Was told to comeback for my hotel voucher, none. Had to book my hotel voucher the usual way through Dubai Connect despite having been told twice to comeback to the counters twice.

Worst ever. No assistance and communication from Emirates crew. No visibility of when the flight is flying. Couldn’t understand if we can go to lounge to take rest. Emirates system at a certain point said flight is not operating and suggested to take the next flight and in few minutes it suddenly opened the gate for boarding. unsupportive and rude crew. Worst experience ever. Flight was delayed by 5 hours so need the compensation for that.

Flight from Dubai to Zagreb very bad cabin crew. Bad food

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

Had the salad which tasted awfully spat it out but still got food poisoning 1 after running to toilet crew would not let me sit near toilets I was stuck in window seat

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

More space all around is practically essential on long international fights, and Emirates definitely delivers. But food selection and taste was only average. Otherwise, the flight was smooth and the cabin crew service was fine.

I bought Business class ticket but they treated me like economic class. No lounge allowed at check inn I have to take stuff out while other passengers have more than 25 lb in bag. Because I bought tickets from other than airlines . It’s discriminations from airlines to passengers.

Meals was mis-served inspite of selecting vegetarian food! I was served non- veg in both flights ie., IAD to Dubai and Dubai to Hyderabad. Staff was not that friendly

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

We bought the business class tickets. The check-in staff and onboard crew were excellent, providing commendable service throughout. However, it was disappointing to find that China Southern Airlines does not have a lounge at SFO. Instead, passengers were provided with a $35 per person food voucher, which fell short of expectations. Furthermore, the quality of the onboard food left much to be desired, marking a significant decline compared to our previous flight experience in 2019, prior to the pandemic.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."

For the price we paid, I couldn’t complain. Was good value for money. Service was excellent but food was mediocre. Crew were excellent and spoke English. You will never go hungry. The food was ample but was mediocre. Entertainment limited and wifi doesn’t all allow you to access some social media. The best part was comfortable seats and bed (business class) with a screen to close out the rest of the cabin.

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.

Cheapest option from Gatwick £400 cheaper than Emirates and Qatar. Entertainment no where near as good as Emirates and Qatar, but saved £400 so all good.

The flight was cancelled without any reason. But the next flight to Shanghai has to be cancelled to pay penalty.

Gatwick London-Shanghai -Bangkok.. Would have liked entertainment screens, but I know these planes are not that new. Cheap flights at the time of booking, Emirates wanted double so you get what you paid for. I would fly again with them, but if Emirates was the same price I would go with them.

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.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

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.

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.

I couldn’t select my seat until I checked in at the airport. Extremely difficult to talk to a customer service representative. Also, the gate announcement doesn’t appear until less than an hour before boarding.

They over sold the flight and I was not able to board. Had to buy two tickets so I would not miss my connection.

Wonderful service and very comfy in the bulkhead in Economy Plus! Delicious food.

On the flight from Venice to London even it’s short, 2 hours 20 minutes and mostly people are on vacation, it’s ridiculous to change money for the cup of tea or coffee. Also it’s to much to charge 80$ for 1 piece of luggage

Flying economy is like being packed into a sardine can.

The BA team at Sky Harbor is deplorable, full of unnecessary attitude and poor communication. It seems like every member of the team was looking at another to solve the problem, instead of taking agency to do so themselves. I saw no less than 6 altercations with the same gate agent where he threatened to revoke the passengers boarding pass for asking a wildly reasonable question, something as simple as where the cue to board was. I’ve complained to BA before but it seems this isn’t an issue for them, which is very disappointing

Boarding poor in London,ok in Chicago. Don’t like Heatrow/terminal5

It was very good. We got a late start by about an hour and a half. However I worked rather have that than crash. It was purely mechanical. They had our tickets ready when we came off the plane in London for the next leg. The only mishap was when we got to Lisbon my husbands luggage made or bit mine didn't. All was not lost because I did finally get it 2 days later. I was really pleased that they c made the effort.

Business lounge in Naples is very spartan with poor food and not very comfortable. Late departure from gate, ride bust then wait on runway for 30 minutes. Almost an hour late departing. Business class was middle seat empty. We exit row do reasonable comfort. Service was friendly and prompt but drink offerings limited with some selections requiring extra charge.

Liked that my American Airlines status seamlessly transferred to BA so luggage check was free. Flights were on time, boarding quick. Wish they didn’t assign connecting gate so late at Heathrow.
