I have been through Baku airport twice first in August last year and again in July this year in and out both times. Frankly my experience has been a lot better than most of what you see from other comments here: yes it's not a great airport in terms of facilities despite all the space the bureaucracy is not all too transparent or efficient either and you have to watch out for scams and extortion but during all my visits I have met neutral or even friendly staff at passport customs and check-in and no attempted requests for bribery. Upon arrival the visa procedure (for Westerners) is a bit odd: first get a stamp at the passport desk then back to the visa desk and then through to the passport desk again. Some people were not aware of this and queued up at the visa desk first and were then sent to the back of the passport queue first and then again the back of visa queue so that it took them an hour extra to get through. I was advised to sit at the front of the plane on my way in and pre-fill the visa application form in order to be at the front of the passport/visa queue; in reality I was all the way back but in the end this didn't make any difference as the people who were at the front still had to wait just as long as me for the luggage to arrive. Do bring your two passport pictures with you if you don't want to pay 10 dollars (or euros although that's worth 50% more) for them at the airport. The triple security checks at check- in are just a joke as I managed to 'smuggle' both a pocket knife and a bottle of water in my hand luggage through all 3 of them (I found out afterwards). I do suspect that my relatively good treatment may have to do with the fact I was flying European airlines (BA and Lufthansa respectively) on both occasions if that can be useful advice for anyone. In my opinion this airport is not as bad as most others in similar countries.
