Hyderabad to Chicago via Delhi with Air India. In November 2015 I flew from Chicago to Delhi. That time my experience was pathetic.
The staff were lousy, seat was uncomfortable, the table was cracked, 80% of the inflight entertainment system was not working and the toilets were smelly. This time I had to book my tickets with Air India ( no other option was availiable) and I felt a good change in the customer service and the aircraft itself.
The crew was quite attentive this time and were happy to serve. They were smiling and friendly. The seats were quite uncomfortable but the entertainment systems were working fine. Food served was good, although the gap between the second and last meal was quite a long. However when asked they offered juice and half sandwich to me. Toilets were clean and after experiencing a positive change I felt that they deserve a good review too.
