The grieving actor, who lost his 16-year-old son Jett earlier this year, remained at bay while director Tony Scott, co-star Denzel Washington and the rest of the team promoted the remake of the classic 1974 action thriller.
Travolta revealed he was grateful to have such colleagues and their support while he tries to cope up with the tragedy.
"It was a labour of love to work on this film with the producers Todd Black, Steve Tisch and Jason Blumenthal, the director Tony Scott, and fellow cast members Denzel Washington, Luis Guzman, John Turturro and James Gandolfini..," Contactmusic quoted him as saying on his official website.
"Tony, Denzel, Luis, John, James and Sony Pictures stepped up without hesitation to help promote this wonderful film, and their unselfish efforts have allowed my family the additional time to reconcile our loss."
Jett Travolta died after suffering a seizure during a family holiday in the Bahamas in January.
