According to Sata, the Azores Air Pass is not available in the US, but that it can be purchased once a visitor arrives in the Azores. Beyond that, I can't find much information. Our plan is to visit several islands, and line up most accommodations in advance. Is it feasible to wait until we arrive in the Azores (May/June) to book and purchase our inter-island flights? Any idea about the cost of the Air Pass and it's particulars?
