Very beautiful airport with friendly staff, not too crowdy. Has a Segafredo in the area of the gates so you can have a good coffee while waiting for your flight.
You can connect to a Turkish GSM operators for a while since the border is very close to the airport. If you are travelling with a cabin luggage, security will probably stop you and check it..
For those incoming to Yerevan. Cognac/brandy (Ararat Akhtamar 15y, Nairi 20y,apricot/peach/berries moonshine stuff) is cheaper in Airport duty free, than you would find at city's grocery/wine stores
