Boarding in New York was smooth and well organized. However, the boarding process in Dubai was less convenient. Passengers were asked to board an hour before departure, but after that we had to wait in another area that did not have enough seating capacity. To make matters worse, the flight was officially delayed by an hour, followed by an additional 45-minute delay while on the aircraft. The food was excellent and exceeded expectations. Seating comfort was decent for Economy Class, and considering the fare category, I have no major complaints. The entertainment system was outstanding. Being able to watch a FIFA match live during the flight was a completely new and enjoyable experience for me, making the journey much more engaging.

The flight was literally cancelled by emirates and you sent me to a scammer website of Underpricer.com for the tickets who still has not provided a refund for one ticket. Kayak has gone seriously downhill. If you are going to redirect people to a site then ensure they are reputable and not untrustworthy scammers. Am never using kayak again after this experience. And update your algorithm or whatever so you don’t send out auto emails checking on flight experience of cancelled flights due a literal WAR!! also I have complained about underpricer and nothing from kayak. So disappointing

Difficult to find some food option for gluten and dairy allergy. May be a fruit salad would be better

What a great trip . From check in to the upgrade we received a big shout out to Cleverson who was able to help us navigate the whole process super patient and was just one of the best customer service experiences we received in a very long time . The amazing staff on the flight who went above and beyond to make sure we were comfortable amazing food and service if you have te opportunity to upgrade it's a must and well worth it.

in today's time, an airline like emirates didnt serve drinks as requested, Excuse was full flight.

I lost my lock from my luggage, I don’t know someone took something from my bag.

Very good ..nice comfort..crew service was good..and no delays in time ..they always on time..

Food was not great. Crew members were created hassle with attitude at the gates and wasted my valuable time. I have been traveling in Emirates airlines many times. Over all not happy flying in Emirates airlines this time. Seats are very small and not comfortable. Seats looks like very very old and congested. It would be nice if they fix these kind of issues. I hope my next trip will be hassle free and comfortable journey in Emirates airlines. Thank you.

Everything was perfect... especially air hostess were excellent in attending people.

The non-veg food was horrible,esp chicken. Flight got 2 hrs delayed in Dallas,Texas.I missed my connection flight&waited 8 hrs.I got really sick& hospitalized soon after I landed.I traveled with someone who have sciatica nerve problem.Wanted to lay down in the empty reserved seats in while the flight was in air,the crew chased us out of the empty seats. Until the flight landed those seats was useless for anyone.

All good. Over four hours flight if provided snacks like Qatar Airways would be better

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

The Qatar Airways staff pre-boarding and also on the flight from Dallas to Doha were incredibly mediocre and arrogant. Consider retraining these individuals Other flights were ok.

Worst air experience in whole life . Boarding and checking was hassle as they did 3 times. Crew team was clueless about passengers need. Despite of passengers raising hand , they were resetting the program

It was good no problems made it on time for the next flight overseas!

Not impressed. Only allowed one carry on on such a long flight.

INDIGO connection is extremely bad.. will never book QATAR flight with Indigo connection.. I spend more money on Qatar flight to get better service but Indigo connection is worst than local flights

Qatar said few times that the luggage will be at the final destination but they were wrong. Please check where your port of entry is at the destination. This is where the luggage would be. The food was terrible.

The Crew was Very Nice but the food was Very Disappointing - the seats were Very Uncomfortable

The screen was not clean.It had stains of previous customer .Also the toilets..My daughter got urine infection. Not happy with the cleanliness of aircraft.Also requested multiple time hot beverages but not served at all sighting disturbances. Request on behalf of every passenger please sanitize and clean as we stay for 15 plus hours..

The flight from Houston to Chicago was delayed, causing us to miss our connecting flight to Madrid, losing our Rental Car booking in Bologna taking alternative travel routes to get to our initial destination in Pizza by the 15th. We got the notification of the delay as we were traveling the 3 1/2 hours from Corpus Christi, Texas to Houston Texas for the initial flight. The delays hauling luggage all over Milan‘s Central train station to catch trains to get to Pizza the same day resulting us arriving in Pizza at 2 AM leaving us no time to rest as there was a 9 o’clock checkout time the next morning. The first 72 hours of the trip with nothing but headache, a knee injury from the excessive walking and a delayed car rental replacement, which ended up costing significantly more.

The ground crew members at check in counter were courteous. The boarding was seamless. Flight departed as scheduled. Service on board was great

The seats seems abit small and the reclining is too much, the seat in front of me came back too much and made it uncomfortable for me.

IAH to Istanbul was outstanding across the board. The flight from Istanbul to Male was good, not great.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

Good food and wine. Some of the Guy who are in charge to board Passengers on the plane couldn’t use the word “Please” to direct them drop their hand luggage to be loaded on Plane bcos he said the inside storage may not have enough room for all.

Four of my family members was settled in a different seats. I paid extra $200 dollars for 4 seats just to be all together, but they settled us on separated seats. After a lots of time they put us 2 and 2. My kids are 9 and 13 . How i can leave them alone???

Temperature in plane in both segments was warm. Otherwise, great experience

Love that they had a bassinet for our child during the flight. Thank you for that big time.

Awful , hidden charges for the luggage was a very awful thing, very much a scam , booking the flight thinking the luggage was included was definitely a scam , then the girl that was taking my luggage Ayrlease the airport was an absolute awful , telling me if I don’t have money to take my luggage with me I can just throw it away , how professional, NEVER AGAIN .

Connection booked by Etihad was delayed and upon arrival to counter they closed it and denied boarding although there was still 15 minutes to go . Manager Karen was very rude and did not want to listen seems there as overbooking and canceling boarding was the only solution..

Doubled charged me for luggage and lost $520, dug much into my travel budget.

On time and no hassle luggage policy (2 checked in and 1 cabin bag)

i have book the flight with baggage. and i have paid $800.00 for the baggage. when i contacted to JUSTFLY Costumer Service they told me that my baggage was included in the booking. then why i have to pay. i am going to file a complain against it. $800.00 is not at all small amount

They lost the baggage and said it was deleted from the system. I had baggage tag so was able to file the complaint but there was no PIR number and update so far

Very disappointed to not have lounge access The shorter flight seats were uncomfortable

Dear Team, I purchased a full travel package that included 2 checked bags through you and JustFly. However, when I arrived at the airport, my ticket showed 0 checked bags. Since I was traveling internationally to India with 2 bags, It was a $200 per bag at the counter, which was extremely disappointing. For an international trip, why would I ever choose a no‑bag option for only $20–$30 less? This seems like an error in the booking process, and I am requesting clarification and a resolution. I have called JustFly and on phone for 1 hr :53 min and they couldn't help till I show some kind of proof etc which isn't possible but besides that love your service and using it for years !

Good one but just notice that you have to ask several time to get water or coffee .

It was fantastic. The flight from Chicago to Abu Dahbi was fantastic. The crew, food and service were amazing. Everything was handled by the crew member assigned to us , Nicholas, was usually done before we asked for it. Highly recommend Etihad!
