Please tell me that how far in advance I should be at the airport . And after dropping off by taxi at airport, where should I go for boarding, I mean the exact directions towards domestic boarding counter. I am first time travelling from KLIA to Langkawi and not aware of the lvarious counters / locations of the airport. It's a big airport and I am afraid being a new here, I shouldn't miss my flight if I take too long searching for the domestic flights counter. Mine is Malaysian Airlines. I appreciate your help. Thanks.
