This airport has come along way in the last decade. The Latvians are a very stern humorless and xenophobic bunch and Soviet style customer service is still the rule so don't look for a warm fuzzy experience but all in all for an old soviet era airport its not bad.
Looks fairly modern but lacks good places to eat. Often extremely crowded and nowhere to sit down. People were just sitting on the floor.
Customer Service / Information - arrogant, dismissive, and limited awareness of how public transport from/to the airport or unwilling to divulge information . YOU ARE ON YOUR OWN. Rest of staff / officials helpful and cheerful. Do you homework BEFORE going to the Airport and you will be OK.
i gave such ratings as passenger of the flight HY-101. We stayed in small area as priseners.
I spent a few hours waiting for a bus and I felt bored... not even an Internet spot exists in this airport. In general it's confortable...
