Fly with an airline that allows early online check-in so that seat can be chosen free of charge. Always allow plenty of time at the airport and travel light with few bags.
BarryFlew with British Airways-Jul 2024
Check if there are seats at the rear configured as 2-4-2. The extra space on the aisle is very good to have.

They need to take training from emirates or Singapore airlines, it’s premium in pricing but poor in standards

They need to take training from emirates or Singapore airlines, it’s premium in pricing but poor in standards

Boarding crew at the gate mostly were being difficult. But one on board much better experience with crew and service!

Good. However the passenger in the search next to mine kept coughing. When we landed in Dallas we had to pick up.bags instead of going strait to the destination (which passengers do in Atlanta)

Although I am a lifetime Gold Premier member on another airline association, I was placed in a inside passenger seat on both legs of my journey from SFO to HKG and onward to NRT. However, i was lucky enough to have befriended two other passengers (who were related) in my row (row 62) and therefore was kept entertained with conversation for a large portion of the overnight flight from SFO to HKG. Normally, on a Star Alliance carrier, I typically can have the seat of my choice (aisle seat) and also a Premier seat (wider and longer legroom). I was a bit disappointed that no recognition of my Gold Premier status was acknowledged by Cathay Pacific on either of my flights on Sept 26-27. The food was actually very tasty unlike the typical economy class menu. Also I appreciated that the dinner drinks were served first (prior) to the main meal on the HKG to NRT portion of my flights but drinks were served AFTER the meal had been distributed (less appealing for thirsty passengers). I was happily that there appeared to have ample cabin space for most everyone's bags ---although I did have to pay more than $400 in extra baggage fees as I had brought 4 bags with me Overall, I was impressed by the diligence and professionalism of the flight crew.

In between two meals period they're not providing something like banana / cup noodles or bugger. It's really fell sad that I was asking have to wait for 3 hours for second meal. (breakfast)

The crew are timely, friendly and professional. I was very impressed.

They overbooked the flight and reassigned my seat. To add insult they lied that my assigned seat was broken and promptly gave it to someone else

Boarding was good and efficient, however since this was a late flight I spent most of the time sleeping so can't express any further opinions

See previous answers. Also food options limited, entertainment difficult to use and did not work properly, lay flat bed is quite big but very hard and uncomfortable

Would have liked working outlets on the flight. The first meal was very bleh, the second meal was a lot better so overall okay meals

The flight from Zurich to Montreal was not a good experience due to 3.5 hour delay

Really BAD check in experience. My bag was left in Geneva and I have not received it yet. I have been in Stockholm 5 days without clothes to change. The flight was good but very unhappy with the post service support.

Everything was fairly easy just hard when you get to Heathrow not know your Gate number until an hour before but otherwise really everything great. Did not get my texts in time though to do me any good but that is why I still like everything the old fashioned way and print everything out.

I purchased a one way business class ticket from Geneva to Miami but the check in agent said I had an economy ticket and later upgraded to business class. This was not the case, I had a single business class transaction. I was forced to pay for my second checked bag. I am unsure of why this happened. But I won’t use Kayak again for business class tickets.

My luggage did not make the connection and 4 days later I still have not received it.

I have no complaints. The crew was attentive, pleasant and heloful

So disappointed, the flight from Zurich to Sarajevo was delayed for two hours for no reason, they were also shifting gate several times prior taking off

Delayed flight… caused the missing of my connecting flight in Zurich. Had to wait 10 hours in airport for new flight which was also delayed by 1 hour. No apologies and minimal compensation.

Flight canceled Terrible Post flight management Kept in airport 1 hours with promises of transport but none came

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Weren’t even given earphones to use the entertainment system

Very friendly and attentive flight attendants, good food service. Seat was comfortable. However, the in flight electronics were poor. The screen froze repeatedly; the controller died; the headphones are a hit or miss; the wifi wasn't usable. Very scarce communication before the flight (no email reminder). Almost impossible to understand in-flight communications (audio was very poor).

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

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

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.

Communication between the captain/crew and the passengers needs to be improved.

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!

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 real problem is that the WIFI for a westerner is terrible. To not be able to properly use Instagram, Whatssap on such a long flight makes the flight miserable. The flight attendants are all like busy bees, efficient.

While boarding at PVG, there was a ticket checking by the gate, then there was another ticket checking right at the bottom of the escalator, which created quite a dangerous congestion. Don't understand why the duplication?

The only personel that smiled at all were the flights attendants. Desk agents, lounge people none of them had a smile or even a hello. They were like dealing with dead fish. Again flight attendants were good. All other personnel looked like they didn’t want to be there or help.

Super surprised with the entire experience. Business class is incredible. Flight attendants around the world could learn customer service from these people. Simply fabulous experience all the way around.

Excellent experience however older aeroplanes used by China Eastern Airlines.

Flight was delayed for more than 3 hours, food was mediocre, seat didn’t recline

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 landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

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.

I ordered a drink, but never got it. I ask what type of drinks they had and they could not tell me and there was not printed copy that I could find that is usually on most airplanes. They served dinner and never walk back to see if any need a drink or anything afterwards until they served the snack just before landing.

Check-in wait time was quite long (understaffed for the volume of customers), but energy and hospitality of flight crew was great!

I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

Flight held at gate for other passengers. We ended up being late and missed connection

Should have more cosmopolitan food choices - too many Indian dishes - the only entree not Indian was lamb which I don't eat

The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.

Worst thing: Luggage took forever to get at LAX despite priority bags. Best: Flight attendants were great!

It was my experience w Kayak that was negative. I’m never using kayak again

Ticketing was a bit misleading. Was not immediately apparent that the tickets included no check-in luggage allowance.
