Flying a hold

So a holding instruction was issued, and the A320-200 kept going round. I even got to see the Sungai Johor Bridge (Desaru Bridge--about N1.52534 E104.018383) on final approach to runway 20. From the air, the 4km bridge was quite conspicuous, with the large 'A' support and the many cables running from it. Changi Airport was so busy, we were holding for 30minutes. Right after we landed there was another A320 JetStar right behind...

First time being in a holding pattern. Not much airspace in Singapore-- flew over Johor.(all the dense vegetation---- definitely can't be Singapore)
