According to Ryanair policy:
What you CAN bring on board
All passengers are entitled to bring 1 small personal bag on board which must fit under the seat in front of you (35cm x 20cm x 20cm). Examples include, handbag, laptop bag, and a small back pack.
I'm afraid for my MacBook's safety, so I want it to be with me.
Can I bring it to a cabin? Maybe someone has own experience.
MacBook Pro 15" size is
38x27x2.5 with its bag and I don't want to place it under the seat...
Thanks in advance!
