Singapore Changi Airport began construction of their Terminal 4 (Jewel) back in 2014. The target completion date is set at early 2019.
If everything goes well, we can eagerly look forward to the grand opening of the Jewel very soon. I am also certain it will be a huge fanfare. Recently, I also saw the promotional video of Jewel (re)surfacing on my Facebook wall. I would like to share them with you here.
