It took almost 4 hours to collect the luggage from the belt in Lagos. Really pathetic. Flight attendents from Dubai to Lagos were very busy and were not responding at all.

It took almost 4 hours to collect the luggage from the belt in Lagos. Really pathetic. Flight attendents from Dubai to Lagos were very busy and were not responding at all.

I love to travel again and again in Emirates. Keep up the good work.

It went well except at delhi airport they told me that my flight is canceled and only after talking to manager they were able to find seats for me and my wife

I liked the newer aircraft CRJ-550 since it had WIFI and the seats are more spacious.

Food was great. More vegetarian options on menu would be great!

On the DXB to IAD flight, missed the snack between the meals again...

Checkin and boarding staff at Delhi Airport is not cooperative with passengers Their behavior very humiliating . They don’t allow Lap top bag and Ladies’ purse/vanity bag which most of the airlines allow besides cabin baggage and check in baggages. They try to charge extra payment on the pretext of small variations which normally other Airlines staff don’t do. Airline staff should be courteous & cooperative but check in staff of Emirates Airline at Delhi was not so at all.

Overall good but one thing I didn’t understand is why they didn’t allow me to pick my own seat.

I booked the air tickets through Kayak for traveling to India. I wasn't sure how to tackle the ticket booking process but it was so much easy with the Kayak , Surprisingly I even found the Indian branch of Kayak which I used for the domestic travel. All in all , it's most convenient site to use here as well as abroad. I will definitely use Kayak for my future travels.

They transfer passengers by bus in dubai don't put the plane on gate, thats not good very hectic and so many security checks. I Prefer direct flight to usa in future. Checking in crew in india need training. Send us separate email, clerarly mentioning about carry on changes when traveling from india to usa. Or It shd be same as going from usa to india.

The boarding of this flight was total chaos. For some reason, all passengers had to stand in a lengthy line at the gate to have our passports checked for the FOURTH time. No reason was offered for the necessity of the fourth re-check, and when we got to the end of the line, the check was perfunctory. There was little to no crowd control at the gate and in some cases, tempers were flaring. On the other hand, once we got on board, everything about this flight from start to finish, especially the quality of the food and the service, was probably the best I have ever experienced..

One would expect far better service and quality of seats from Swiss. The crew was super cold at best. My wife and I are both Star Alliance gold members and none of them even bothered to come and acknowledge our status and make us feel special. Seat is in need of a major overhaul. It’s simply outdated and the TV screen is far too small. Food and drinks selection was very sub par.

The seat and leg room is small on the 2 seated row. Otherwise, very good crew and service.

The meal was wonderful and strawberry ice cream was a plus.

I haven't flown Swiss in a long time. I was disappointed that after paying $14,907 for 3 business class seats, we still had to pay another $200 for a single business class seat. All the window seats used to be single seats. Now it's every other one and if you want a single seat it's extra. Also, The double seats do not have pods or any privacy. We landed in Chicago after a long 10 hour flight and our connecting flight was on United. Because we do not have status on Swiss, we were not allowed to use the United lounge, even with business class seats. My father is on crutches and we had a 4 hour layover. No lounge was also disappointing. All of my status is on British Airways so I will go back to flying BA. We flew Swiss because my father did not want to go through Heathrow. On a positive, the crew were super nice and accommodating for my father who had recently had hip replacement surgery. Food was okay. I"m not a good person to critique the food, I never like airplane food.

-Swiss airlines online check in app crashed multiple times -Zurich airport does not have very many bathrooms accessible to people with disabilities - closest disability accessible bathroom to departure gate was 1/4 mile away.

Great food - movie selection was good. Plane was a few minutes late but got to destination on time.

It was great! Friendly crew. Good food and service. Great snacks. But one of our luggage did not come to Chicago. Stood at carrousel until the end waiting for our bag and it wasn’t there. Then we had to rush very fast to catch our connecting flight to Cleveland and almost missed it

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

Everything was on time and efficient - expected from a Swiss crew. But the entertainment system was pretty bad - the display was old. Food was pretty bad and a couple of times they started serving drinks and then just skipped past my row (and likely several others)

Seats were very comfortable and the staff too was very friendly.

Good flight. There were a few issues with the flat bed. It was some technical issues. Otherwise everything was good

It was mediocre. Honestly, the flight was late but that didn’t bother me as I had plenty of time. The only thing that bothered me is that the crew never asked to make the beds for us in business class. Maybe the crew was exhausted and that just didn’t occur to them.

On this flight...fine. The one from India to Abu Dahbi, awful.

There was not any issues with the Etihad Airways. Staff was excellent and I love the variety of movies and games that they provided.

i was not allowed to use lounge, although i had business class ticket, and nobody told me my ticket was not eligible to use lounge

Should have had business class line in immigration. Food quality suboptimal

In my opinion, Etihad Airways is a first rate airline except for one important element. On the day before my return flights, when I chose my seats on the Etihad website I was charged an additional $55 (US) in order to sit on the aisle. I was not at all happy about this additional "hidden" charge and I felt cheated.

Good leg room and I picked the seat in last 24 hours. Food was tasty with 2 full meals and first one smaller. The crew as expected courteous and on their toes serving extra water and items in between.

Nothing was good everthing was hopeless especially your staff at indira gandhi international airport india.Everthing has deteoriated

Flight was delayed by over two hours and that meant my connecting flight was in jeopardy but there was no acknowledgement or help from the BA staff

I Keep your expectations to low to middling with BA, or most European/ US airlines these days.

British Airways offers amenities subpar with all other airlines flying internationally. Sharing tis based on my experience with flying at least five other airline between IAD-DEL in the last six months.

Experience was bad. In business class, they ran out of food choices. Luggage was delayed by 2 days in both to and fro flights, ground staff was not helpful, took 3 hours to log the complaint for missing luggage.

Very bad because flight was cancelled and they never informed me i have to wait for three days in hotel to get another flight

Missed food service or not enough food available to serve the passengers. Very poor leg room in economy. Uncomfortable and old seats with some of the seat covers coming off. Lights, entertainment system and call buttons not working for an entire section of the flight between Del-Lhr. Very poor experience overall.

Biz class has a middle seat. 🙄. WiFi only for first class. No free seat assignments. Basically nickel and dime approach. They need to take lessons from Singapore Air and the likes. Never again.

I have not used food or entertainment all other services I used were simply excellent. BA crew is always good in service. The BA Crew at anygiven flight is simply amazing.

The behaviour of Cabin Crew was really bad and they didn't serve food in my 10hrs flight even though I booked my flight food . They didn't treated me well. Seriously inhumane people. Moreover, they have made fun of my religious belief as I was carrying lord Krishna idol with me which is highly unacceptable. Our connecting flight got delayed and for providing the information regarding next flight and other immigration there was no guidance provided at the airport. I am really disappointed with the airlines as they have hurt my self respect as well my religious sentiments during my whole flight.

The only issue we had was damage checked in bags, out of 8 bags only two arrived at the destination. Out of 6 remaining bags one came late at night and it's all broken. Still awaiting 5 more bags to come.

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

We trusted KAYAK and Air India but no one is responds for the lost of baggage 🧳 2 (bags). My in laws are totally lost hope for this kind of situation to travel any more.

Worst International flight I ever had in my whole life time. Boarding is the worst of all and flight experience was also not good. Screens were not working, seats were not comfortable and lot more.

Very good compare to before . Nice food and tv was working

worst airlines I have traveled to so far. There was hair in the blanket and pillow they provided. On my round trip to India, not even once did the entertainment console work, the seats wouldn't recline, Some of the air hostesses were rude and not helpful. Not planning on using Air India till they have new planes.

One of worst flight. No Videos/Movies. The Seats are not good.

No in flight entertainment 2 toilets were out of service Crew was good, food is also good

Seats were broken. None of the entertainment systems were working.

Plane is old. Seats are broken. Entertainment does not work. Food is ok. Flight attendants are courteous and try their best. Take this flight if you get the cheapest ticket. Otherwise, look for other carriers.

Our flight was cancelled due to technical issues. Air India staff caused each one of us to go through nightmare before finally placing us in a hotel by 2 am. I was asked to share a single room with a stranger. I insisted that I cannot share the room as I needed privacy due to my vulnerable medical situation (Heart issues, High blood pressure, High Cholesterol and Type 2 diabetics). Even after explaining my medical situation and the need for privacy, Air India instructed the hotel to charge me Rs 4000 for the room and I was forced to pay the amount at 2 am (roughly $49). Air India should refund the amount I paid for my hotel room, at the minimum. Air India didn't have any Standard Operating Procedure to do what/how/when/by whom under this situation. Mom with babies, Elderly people and people with medical condition like me were forced to wander from here to there and talk to each person right from 10pm all the way till 2am. The Air India staff didn't have PA system to give a consistent announcement, instead they were murmuring on a one-o-one basis with more than 200 passengers. It was a sight of utter mismanagement and lack of commonsense. I will not ever, I MEAN EVER TRAVEL an Air India flight even if it is free, and will not recommend Air India to anyone I care.
