we had more than 3.5 hours to transfer to another flight from a different airline and barely made it.
1.5 hours walking and standing in line for the immigration stamp! On the 10 luggage belts our flight was not displayed anymore but we luckily found it by accident.
It was pretty difficult to find out that there is an airport train to bring us to the other terminal. But which one and where? You need local currency or credit card to buy a ticket for going to the other terminal! How stupid! We were able to pay it and had to wait 15 minutes for the 3 minutes ride. Checkin our luggage, security check, migration process & ride another train!
we arrived just in time for boarding. the plane left the dock on schedule, but it was standing on the runway for 1 whole hour, so we arrived very late.
Signs on the airport are very confusing.
But we did never get lost for more than a minute. we had good luck finding everything.
There was no time to eat or drink something.

Hundreds of super-fancy dutyfree shops we had to walk by, but that's not what we came for.
