The pair left for Jodhpur early on Thursday.
Dressed in a striped, white kurti and palazzo, paired with a colourful leheriya dupatta, the soon to be bride Priyanka was all smiles as she was spotted with Nick, who sported a white shirt and faun pants paired with a tan jacket.
The former beauty queen's mother, Madhu Chopra, and actress-cousin Parineeti Chopra were also seen at the airport along with Nick's brother Joe Jonas and Joe's fiance and "Games of Thrones" star Sophie Turner.
The couple has hired a few helicopters to take them straight to the venue from the airport.
There will be two different style weddings, one Hindu and second Christian. The ceremony and festivities will be a private affair with only the family and some close friends.
The Mehendi and sangeet ceremony will be held on Thursday at the Umaid Bhawan, where Nick will perform a medley of his songs and Priyanka will be performing a few of her hit dance numbers.
The pre-wedding event will include a haldi ceremony on Friday. A cocktail party has also been organised for the two families, relatives and friends before the big day.
Their wedding ceremony officially started with a puja ceremony in Mumbai on Wednesday.
