Build the journey from San José
Use the actual San José departure airport and compare complete connections rather than isolated flight sectors. If a proposed ticket connects through Panama or a European hub, check that routing as part of the complete itinerary. Confirm connection time, terminal changes and whether the airline sells the journey as one booking.
Transit and the Turkish arrival
A connection through the United States, Europe or another country can involve its own document requirements even when Türkiye is the final destination. Check these with the responsible authorities. Confirm whether the arrival is Istanbul Airport or Sabiha Gökçen, and allow time for the onward ground journey rather than using the landing time as the tour start.
Plan for the actual passport
Check the official entry information for the document used, travel purpose and intended dates. Published historic stay limits should not replace that check. Describe the available days in Türkiye separately from the international travel days, so a Cappadocia or coastal extension has a realistic place in the programme.
