I'm russian. I don't have a Schengen visa and I don't have an opportunity to get one now.
I want to buy a ticket Mexico - Brussels - Morroco of tuifly.
Normaly, if I had a single ticket , I wouldn't need a visa to do a transfer in Brussels without changing an airport, even though I didn't have a Schengen visa.
However, the route
Cancún - Brussels - Enfidha doesn't exist at the website of tuifly. And kiwi.com does have such tickets. This implies that probably there'll be 2 separate tickets, of the same airline.
I'd buy them from kiwi.
The email support of tuifly told me that they couldn't give me an answer about me being able to board a flight, by email. Only in the airport, when boarding, would I find that out.
Question: will I likely be permitted to board a flight? How to increase my chances for this particular route?
