Ryanair Personal Bag - will this be ok?

[AlltheFs]

Flying with Ryanair soon, we have 10kg and 20kg hold bags, on the plane we can have 3 40x25x20 personal bags.

DD’s childs backback is fine, one of our rucksacks is bang on but one is 5cm too wide at the base (but tapers). Will we get away with this if not stuffed? Really don’t want to buy another bag as we don’t use them normally.

It’s DD’s first flight and early in the morning so I want to avoid a Ryanair row (absolutely loathe them but only flight option).

I'd use it if it's not packed fully it'll stuff under the seat fine.

Don't overfill, they won't usually check anyway

I flew to Ibiza in April with Ryanair with just the small personal bag as luggage. No one checked going out or on return and the flight was fully booked.

I would agree with pp ,just don't overfill so it can be squashed into their measuring box should they wheel that out.
