It's between 3 and 4, and it's a nice way to fly international.
It's much better than the old terminal. The facilities and airport staff are very nice.
The security control is efficient and the queues are well managed. Additionally, there are power points to charge cell phones and other devices after security.
There are many duty-free shops and restaurants, so you can eat and do some shopping to pass the time before leaving the country.
After the renovation, things are much better inside with lots of shops and places to eat. It's always busy, but the facilities are very nice.
