An airport official said the aircraft was called back to the parking bay at the time of taxiing.
A source at Jet Airways said the couple was travelling with four big-sized suitcases.
"The checked-in baggage (suitcases) was in the name of Anita Goyal. The baggage was also offloaded, which delayed the flight by more than an hour," the source added.
The flight was scheduled to depart at 3.35 pm. After deplaning the couple, it took off after 5 pm.
Naresh Goyal could not be reached for comments. Response to a query sent to Emirates was also awaited.
The specific reason for stopping the Goyal couple from taking the flight could not be immediately ascertained.
The airline stopped flying from April 17 due to an acute liquidity crisis.
Earlier this week, Hinduja group had said it was evaluating the opportunity to invest in Jet Airways.
In April, Jet Airways officers and staff association president Kiran Pawaskar had written to the Mumbai police commissioner demanding that passports of Goyal and other directors of the airline be impounded as staff had not been paid salaries for several months.
