Arriving via a flight: It takes awhile to get through customs, and then security. A guard saw us and called for "familia" to come through before others (not sure if it was because we were foreign or because we had a little one, but I appreciated it). Took forever for our two bags to arrive. It is crowded and chaotic, and the smell of smoke is constantly there in the building. Baggage claim, security, and customs are all one place in the terminal we were at (2). There was also a desk to stop and turn in your medical paperwork, but we somehow passed it and no one stopped us. I went back and submitted the form before we left just in case. Upon exit, there are lots of locals packed around the gate. Luckily, our driver showed me where to get the money exchanged (I had to go back inside the airport, to the check in area to do so). We did not see any food or ETECSA (WiFi) when we arrived. Best to book a driver in advance so you do not have to deal with the crowd or try to negotiate pricing (or have to burn cash- we did it all online before leaving home).
Departure on a flight: Upon driving up to the terminal, we saw a food kiosk and the WiFi kiosk at the far end of the terminal. No wonder we didn't see it when we arrived. Check in was easy, but they only check in the flights one at a time, it seemed. They were not accepting people on the later flight yet, just the earlier flight. We were not allowed (by the vendor) to buy a bag of coffee because she said security wouldn't let us bring it through. Easy to get back through customs and security. On the other side are some shops for souvenirs (not much though), and duty-free alcohol and cigars. The food was sad, and despite putting napkins with our sandwiches, we were not allowed to have more napkins even though the little one knocked a drink over. We also couldn't get napkins from the bathroom, as toilet paper was all that was there, and they wanted to charge for hand towels (and there is no seat on any of the toilets there, which is customary in many public places). Not a great way to start or end the trip.
