Hmmm....looks like the IDR strengthen against the SGD for 2019.
Indonesia domestic flight air ticket during CNY 2018 was about 1.9 juta for 2 way,today its like around 3.25 juta.
Lion Air used to not charge extra for passenger bringing more than 7kg on-board (for hand carry bags),Jan 2018 they start to impose extra charges.
CNY time, horizon ferry ticket going to Batam cost an extra S$12.00 over the regular S$48.00...i believe hotel room wont be low too (which is why i book them few months in advance).
Looks like Hang Nadim price is going up,not a good sign.
Update as of 13th Jan 2019 :
Horizon wont be charging an extra S$12 for the CNY 2019 ferry trip to Batam Harbour Bay,as according to the Horizon Ferry counter staff/s at Singapore Harbour Front. Just updating.
