The accused were identified as Jaspal Singh, 35, and Charandeep Khaira, 36, who had come to New Delhi from London to attend a marriage ceremony in Jaipur, said Deputy Commissioner of Police (Airport) Sanjay Bhatia.
Their breathalyzer test indicated they were drunk, he said.
On March 29, while they were on the flight, they asked the air hostess to get them some food. When she took some time to respond, they got irritated and started making lewd statements, police said.

At the same time we urge our passengers to draw a line of ethics while flying and using our services so that it does not cause inconvenience to either the airline, supporting staff or our valued travelers," Air India said in its statement.
