General questions about choice of airlines to fly to India

Hello folks,

Following my questions about Delhi airport transit, any words of advice on whether to pick Emirates or United airlines to fly from NY/ NJ to India? I hear about random cancelations of Emirates flights--not sure if people have experienced it on United.

Also would love to hear about anyone who has traveled from NY to Hyderabad--and what they might have used to travel (airline).

Thanks as always
