The leg 5 preview sure implies that the flights next week are not provided.
They are provided if you go to the designated travel agency.
the fact that there are so many production-provided flights, but it's because the Malaysian legs weren't planned and they had to have provided flights to and from Malaysia. Hopefully, teams will HAVE TO FIND THEIR OWN FLIGHTS from Sri Lanka to Rome, and throughout the rest of the race. For the first HALF of the Race, teams have been provided flights
Leg 1 (Los Angeles to Guangzhou) Two provided flights (standard for Starting)
Leg 2 (Guangzhou) No travel, as teams stayed in Guangzhou
Leg 3 (Guangzhou to Sabah) Two provided flights
Leg 4 (Sabah to Kuala Lumpur) Three provided flights
Leg 5 (Kuala Lumpur to Colombo) Provided travel agency, still provided flights
Leg 6 (Colombo to Kandy) Teams most likely traveled by train.
