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

Charged for internet that never really worked. The food selection was just ok.

My favorite airline when traveling to the UAE. Great food and great service.

Meals were delicious, however I got hungry between dinner and breakfast.

My last few flights with Emirates have always been delayed at least a half an hour. When my layover is only an hour and a half to two hours, 30 minutes makes a big difference. I’m going to check out other airlines.

The entertainment selections are amazing. But the live TV is sometimes spotty. If you’re going to have it, then have it. If you can’t make it consistent, then, perhaps it’s better not to have it. The crew are always cordial when approached, but they seem to do the minimum and sit around, talking to each other in the back of the plane during the flight. I realize that delays are not always predictable, but I missed my flight in Dubai because we left 90 minutes late from Washington. I will say that Emirates took very good care of me in Dubai. But I would rather not be delayed.

Emirates is usually on time, but not this trip. Also, during the flight the attendants disappear unless called upon. Very strange. I have watched the quality of Emirates service diminish over the last five years.

Everything was perfect except boarding . Have to wait @ gate for 45 minutes after announcing boarding ..

Excellent food and beverage Excellent cabin crew Live tv could be better

Flight from USA to Dubai was comfortable. There is some serious miscommunication between the staff who does checkin and immigration staff in India. Air Suvidha rules are enforced here as a requirement by the Indian government and without it not allowed to board the flight. The Indian authorities don’t even bother to check it. Please update either side of aisle. Vegetarian food from Dubai to Bombay was not that great at all. It was cold and chewy. Dubai being a hub can provide better options. Staff is very good and took good care of passengers. Please appreciate their hard work.
