Although this is my 26th trip to DR it may be the first regular scheduled flight (all others were charters) when I asked about a tourist card Air Canada says "buy it when you get to the airport in Punta Cana for $10 US" but I have always been supplied one by the tour company with my tickets. If I recall there was some discussion here about getting it after arrival in the DR and the suggestion was that trying that could become a hasle. Any comments would be useful.
