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

Everything was great except the boarding experience. After the check in, they "packed us" in a small area, very hot there. It would be nice to be aware of this, I'd wait on the outside area

Very good from the beginning to the end. Amazing experience

Chaos at the gate while boarding - no clear signs or announcements

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

Fly Dubai takes low cost and thrift to new depths in terms of service levels, terminal 2 is grossly inadequate for capacity and resembles a crowded buss or railway station,, the fly dubai( Emirates) flight is never on time(was 2.5 hrs delayed), and this is not an isolated experience, the flght air conditioning was turned low while we waited on the tarmac for take clearance to save fuel, should say more!!!! The depths! I only fly this airline from a compulsion, emirates code shares for connections to Muscat

They changed the flight time without telling us and were unwilling to help with rebooking because we booked through orbits/kayak

I liked everything: the service, the food, the cleanness. I flew last year with Qatar Airways, so I can compare. Emirates did much better! Especially their meals and service.

Emirates did great! I liked the service, the food, cleanness, and the flight was on time. Much better airline than Qatar Airways I flew with last year.

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 .

Good service. But on flight to Kochi no entertainment except in app. And no working outlets to charge phone.

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!

Was so disappointing. Business class with no TV, uncomfortable seats. Had much higher expectations.

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

It’s a business class ticket but they didn’t give a lounge access

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.
