I am flying internationally from a balkan (non-EU) region to a EU region.

While booking the flight I omitted one of my surnames. Let's my name is F S1 S2, meaning a first name and two surnames. I indicated on the flight ticket F S1. Does that cause any issues? I thought about changing it to prevent any issues but it costs me 70€ if I want to do that change.

Have you had any experience regarding this?
