The good things first, the indonesian people are nice, Jakarta has a lot of things going on so you won't be bored.
Now working for lion: I am sure you already know what's all there is to know.
Keep in mind about the new dgca rules too, they don't want a lot of foreigners flying in Indonesia.
110 is what will be shown on the computer, expect to fly over 110. As you do your schedule expect them to be deleted so they can make it legal on computer.
You will be flying 5 days on one day off.
Jakarta is not a cheap place to live if you are an expat. A decent apartment in a decent area will cost around 700/800 usd. If you eat out expect around 70/100 usd esp if with company.
