Transportation Minister E.E Mangindaan has said that the number of people traveling to their hometowns during the annual exodus this year will exceed 19 million, a 3.83 per cent increase on the same period last year.
"Careful preparations need to be made because the number of travelers is increasing," Mangindaan told reporters in Jakarta on Wednesday as quoted by Antara news agency.
He said airlines would see the largest increase in travelers compared to other modes of transportation.
The number of air travelers is predicted to reach 4.1 million people, a rise of 11.48 per cent from last year's exodus.
According to the ministry's air transportation director Djoko Murdjatmodjo, five domestic carriers Sriwijaya Air, Nam Air, Lion Air, Indonesia AirAsia and Garuda Indonesia have prepared extra flights during the Idul Fitri holiday.
In the seven days before and after Idul Fitri, which is predicted to fall on July 28, the five airlines will add 903 extra flights, to both domestic and international destinations.
Meanwhile, people traveling by road, rail and sea in 2014 was projected to increase by less than 3.5 per cent in 2013, he said.
Travelers using private cars, motorbikes and public buses, for instance, are expected to number 5.59 million people, only a 0.9 per cent increase compared to last year.
"We predict that the peak of the exodus will occur between three days and one day before Idul Fitri and the peak of the returning wave will be four days to five days after [Idul Fitri]," he said.
