Ok, but no entertainment. Left late, but made up most of the time.

Ok, but no entertainment. Left late, but made up most of the time.

May be it is not an ITA issue, but the bags took long time to go out.

Good. But there food was poor quality and 95% of movies didn't have English subtitles

I thought they had rebranded themselves in every aspect but it was quite the opposite. The food was terrible the service was sub-par. Overall it was not a good experience.

Service from staff was poor, food choices were limited. Air plane was not clean or hygienic and seemed like not cleaned for days. Seats were uncomfortable.

service from stAff was barely there , food choices were limited. AirPlane was not clean and seemed like it was not cleaned for days.. Seats were very uncomfortable.

I paid for premium seats and the last minute they changed the aircraft for a bigger one, they bumped me to another seat which was NOT at all comfortable for an 11 hour flight, will fight for a refund!!

The landing was catastrophic. I was very scared. I thought it were my last lminues. Pilotes should be more experienced

ALL services were good. An announcement should’ve been made at the end of the flight that filling out a customs form would not be necessary anymore for USA travelers entering Philadelphia.

The flight was smooth, the premier economy seats were comfortable, the flight crew were excellent. The on board food, however, was AWFUL. I suggest bringing your own food on board.
