Going to Bali in 8 weeks(28th Aug)for 2 weeks(return 11 Sept)we have already paid for our trip, but we are thinking of staying an extra week.I don't believe we will incur any penalty from Garuda if we change our return date now.I understand that you do incur extra charges if you try to change your flight while you are in Bali.
Any advice on this would be appreciated.
