I used this airport flying Iberia to/from Madrid. The arrival service was fast efficient and pleasant - no queues baggage delivered quickly and the immigration officer even welcomed me to Colombia! Departure was another matter. At about 3pm when most of the flights to Europe are checking in the departure hall was so full it was almost impossible to move. When I checked in with Iberia they explained that I had already paid the airport tax on my ticket but I'd have to get an exemption stamp from the airport tax office. This meant another queue for at least 30 minutes; but if I was willing to pay the tax for a second time I could have done so immediately. This just seemed to be a way of extracting extra cash from people willing to pay not to stand in another long queue! Once I had finally checked in things improved and there was little queue at immigration or security. However shopping and catering options are limited and be warned that once through security there are hardly any shops or cafes.
