I am applying for a Turkish e-visa as a Vietnamese national. One of the requirements listed on the website of the Turkish e-visa is that I have to fly to Turkey with an approved airline: Turkish Airlines, Pegasus, Ajet or Onur Air. On my e-visa it is stated that I satisfy the following:
I have a round-trip ticket with Turkish Airlines or Pegasus Airlines.
At the moment I have booked one flight with Turkish Airlines: Istanbul-Amsterdam. I wish to book another ticket, Amsterdam-Istanbul. Does a separate booking with Pegasus, Ajet, or Turkish Airlines constitute a round-trip ticket, or are these considered to be separate tickets? And does this depend on the airline that I fly with?
