I have a messy return next week from the Seychelles. I have multiple self-transfers (separate tickets). I realize its not ideal, but player #2 would prefer 4 hour layovers as long as we're in business. Doing DOH-IST-FRA on TK (one ticket) then FRA-YYZ on Condor then later to US. 5 hour layover in FRA. Non-schengen to non-schengen so no passport control but just transfer security? I assume 5 hours is sufficient. Appreciate any insight.

Regards,
Nathan
