Very comfortable flight. I appreciate the announcements were also in English.

Everything! To start with, seats, food tray table, entertainment console all are broken! Imposing duty free baggage fees for $250 as a surprise penalty cannot be appreciated! Airlines should be responsible for transferring the checked baggages to the connecting flight. Having customer go through the transfer is painful considering the travel tiredness! No soft drinks served on flight is another crumble!

Aircraft interior was in bad shape. Dirty and seats were torn in places. Entertainment system was not working and did not work through out the 14 hour flight! Several passengers had the same issue.

Boarding pass was not printed at the first port & connecting flight didn’t let me go and have wait 10 hours to get next flight.. the reason we pay more money for shorter hold time and get to destination early! Very poor service 😕😕

I did not like any thing . One of the worst flight in last 22 years of my foreign trips. In Average I have 2 trips from US to India

the arm rest was broken. Completely broken. We had three seats and all their screens were not working so I was alone on a flight with 2 little kids and no screens for them to stay busy with. it almost felt like the flight was in that shitty a state that it may not even be able to land. Will never travel on that flight again…..never

Very unprofessional staff, bumped us off from our flight and kept on lying to us with different excuses.

All the electric device ( TV) was not working. It was a very bad experience in the long flight it’s hard to sit almost 15 hours.

No kids meal. While checking in online, no way to select meals.

Food quality and selection very poor from chicago, prabably the vendor is in comparable and needs to.be taken care off. Some toilets filthy but it appeared mostly on passenger's negligence they do not use and keep it clean. Planes are too old and in bad shape erc.
