Time travel back to circa 1960: the building the service the ambience is completely mid-20th century. Check-in is completely disorganized - there was no line for business class you simply had to shove aside others on the line while shouting "business class". Business class lounge looks exactly like a not-too-classy bar from Eastern Europe in the 1950s. Shops are like souvenir shops at a cheap tourist site. But it is not a very busy airport so you pass through everything fairly fast. Fun in strange sort of way. They are building a modern airport for UB so you better go now if you want to experience it before the airport is retired.
