I had purchased my ticket in Havana earlier in the week; it was en e-ticket, and so I was surprised at the delay, 25 minutes at check in, whilst the official went to a back office and wrote out a paper ticket! I queried this and was told that the worldwide disappearance of paper tickets had not yet taken effect in Holguin! The national terminal used this time for a flight to Havana with Aerocaribbean. Everything as before, but two tips for travellers. In the departure lounge was a small counter selling drinks and basic refreshments; it accepts only CUP Cuban pesos, the national currency, as opposed to the CUC convertible peso. Therefore, foreign travelers returning to Havana on an internal flight requiring refreshments need to obtain some CUP in advance of their flight. I would not recommend unofficial currency exchange with fellow Cuban passengers within the departure lounge.
