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.

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

Jain veg meal I opted was super in taste but there was no sweet/desserts with it. I was a big missing in the meal...Please add some sweets to end the meal with 😊

The meat-and-rice combination was a good idea, but the food could use some improvement. The meat looked a bit mushy and almost like ground meat, which wasn’t very appetizing, and the flavor was just average. Other than that, everything else was great.

Weather delayed arriving flight and even though I made the connection, my luggage did not.

Great! Internet is below its competition. Poor connectivity quality and speed.

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

It sure why I’m being contacted by kayak, wrong info provided which resulted in quite a bit of confusion. I booked with experien, why am I being contacted by kayak?

Terrible airline both Swiss and Lufthansa that are part of the same corp. stay away if you can

Close was excellent. Comfort was very good. The food was marginal.

Great flight. I didn't watch the entertainment. I used my iPad the whole flight. But, staff was great, smooth flight, comfortable seat (business seat 7A) and food was really good (I'm a vegetarian).

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.

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

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

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).

Overall, excellent: check-in, boarding, service, and food. The Business Class seating is a little less private and spacious than the world's premier airlines, but still very good for a long haul flight.

Your staff was exceptional. Could teach the other airlines-rules on etiquette, and service. Excellent landings on flights, carried out by your pilots. Only complaint is long delay on return flight in Beijing, onto Vancouver.

Worst than I expected, crew was not attentive, meal was as disgusting , they didn’t even drink selections as they would to other passengers. I felt discriminated

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Food & service very good next I will pick up again

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.

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 !

Basic long haul decent price but U pay for what you get. Over 5hrs of transit and terminal was pretty bare with nothing much to do except the lounge

This was my first time ever flying China Eatern and it will not be my last. I was very satisfied with my whole experience and trip. Thank you very much and until soon.

I was traveling alone with an infant, so the crew was incredibly helpful. Both the international and subsequent domestic flights were impeccable.

Excellent! I had read some negative reviews but I found out that it was not all was not true! The staff was courteous and helpful. The flight take off and landing was nice & easy. The food was good! I asked for a second and I got it easily and without an attitude! All was wonderful!

Excellent experience however older aeroplanes used by China Eastern Airlines.

Delay in off-boarding due to customs at SFO... pilot announcement should have come earlier so passengers don't clog aisles.

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.

Couldn’t fly since they wouldn’t issue a boarding ticket. Something to do with not taking the departing flight since it was cancelled due to weather. No notice or anything about the trip being invalid. The app made it seem like I was all good for it. Never trusting travel agency

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.

Delayed departure, even more delayed arrival, 40+ min waiting on runway before going to gate - horrible Also didn’t get a single bottle of water all flight

Boarding going from seated area to standing outside and then boarding the stairway seemed unnecessary. Drop the standing outside part.

Check in at bcn was a nightmare. In-seat screen did not work, asked for help twice but was not able to use overhead light, watch the safety briefing, watch entertainment or monitor map

Over sold! Never again. Got bumped even though I checked in and arrived on time with all my documents in order. Wasn’t even offer food/drink voucher for the next flight that was 6 hours later.

The flight was canceled. It was very troubling because the rescheduled to Air France was two days later. I incurred two days extra of hotel, was not able to get a boarding pass until I reach the boarding desk at the airline. I don’t know what happened British Airways, but I was very disappointed.

There was a delay on departure. Seat configuration is horrible. BA should not fly this confirmation any longer until the new seat conjugation is installed. Your competition is beating you. Food was poor to average. Not many choices. Arrival was delayed at the gate due to another plane being at the gate. You would think after the delay at the departure, BA and ground control would figure out how to ensure you passengers wouldn’t be late and running to their next connection. Overall, BA continues to be very low on satisfaction. If I had an other choice, I would choose another airline.

Due to no fault of the crew or airline the flight left late but more than made up for it once we lifted off. Captain announced the delay was due to the plane was being worked on. Very friendly, helpful crew, who seemed to enjoy their job. Seats were very comfortable and appreciated headphones and the blanket/pillow in Business class. We were seated in the last row of Business class and they ran out of choices for the meal, however the Flight attendant was able to obtain a chicken dinner from another section.

We missed our connection because they loaded the plane wrong. And had to fix the weight and balance

Check in desks at Bodrum we’re not labelled properly to the point we ended up queuing at the desk only for the signs for business and economy to be put up later and we had to move lines to go into the economy queue. By the time we got to the front, we ended up be ushered to the business queue anyway to get checked in. The flight left on time but then we had to circle the air for a good 15 mins and then when we landed we had to wait to be taxied for another hour. Our baggage didn’t arrive but nobodies did but were told after an hour of waiting that no more bags would be delivered to all passengers had to fill out a form to get their bags delivered. Could have told us that a while ago. Very poor communications

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