Hello, let me explain you the situation.
I'm 15 years old and I'm travelling in a few days with my older brother, who's 18.
I booked a ticket as an adult because I couldn't booked a ticket with my brother, as he'll return earlier than me (I''ll stay 2 weeks, while my brother just a week). Still, in the return I won't be UNACCOMPANIED because my mother and sister will visit me so they will return with me.
SO, IN BOTH FLIGHTS I WON'T BE UNACCOMPANIED.
The problem now is that I can't check in online because when I complete my real age (**/10/1996), the system doesn't allow me to continue.
What do I have to do now? Should I put a fake date, so the system allows me and then at the airport explain them the situation or will Ryanair not allow me to fly?
I would appreciate a helpful response as soon as possible because my flight in on Friday.
