Lesbos, Greece CNN  — 

If you have the right passport, it only costs around $36 to buy a one-way ticket aboard a ferry from the Turkish coast to this Greek island in the Aegean Sea.

The ferry completes the journey in about 45 minutes.

The going rate for Syrian refugees, however, is around $1,350 per person. That money has to be paid in cash to smugglers who shove passengers out to sea on board inflated rafts packed full of dozens of migrants.

Joseph, a Christian who fled Syria to Turkey with nine family members less than two weeks ago, says he was loaded onto a seven meter raft carrying a total of 62 passengers.

Joseph, who did not want to reveal his full name for fear of reprisals against family members still in Syria, crossed the Aegean with his family Wednesday night. All together, they spent the equivalent of around $14,600 for the dangerous journey.
