Not so good. Flight was departed 2 hours late from DC and we missed our connecting flight from Dubai to Mumbai. Our flight Dubai to Mumbai got delayed by three hours. Once we arrived Bombay airport we didnot get all our luggage bags. We were missing two luggage bags so found out that our those two luggage bags are coming in different flight. First they gave us wrong flight information in which our missing luggage coming and wrong phone number to whom we should reach out. I spent hours and hours at the airport to find out our luggage bags. After four five hours later and hectic time at the airport to get our luggage bags. Overall poor communication with emirates staff at the airport and no one is helpful.
