This is an OK airport. It's got Ipads everywhere. They are free to use and are enabled with free wifi. You can order food and drinks from the ipads and servers will bring them to wherever you are in the airport.
That is the only thing good about it though. Otherwise it is cold, dark, messy, and unorganized. The floor staff are rude and unhelpful. The best advice we got was from some random construction worker at the arrivals floor.
I also think that it is ridiculous that the airport "closes"? So when there are issues and bags need to be rechecked, customers have to wait until 4 am when the airport reopens. My friend and I were delayed severely here and needed to recheck our luggage. They told us they couldn't do anything. So we were stuck at the arrivals area with our bags, we couldn't even wait upstairs by the gates. That's ridiculous.
