Had bad experience this time. Didnt like the seat comforat at all. Additionally, this time Emirates came up with crazy seat arrangement where part of family were placed in different seat and this happened with lot of passengers that day on the flight. I think they did this so that next time we buy seat and pay more. The Indian food was the worst. I booked for Hindu meal well in advance and told at the ticket counter as well but got the regular food. Good bye Emirates, will try Qatar or European airlines next time.
