@Chloe I am flying by a Turkish company . I hope it fits 🙏
Our friend told us to avoid them as they are more hassle than they are worth and at the airport parents having to slowly pull their kid along looks harder than just having a rucksack or normal suitcase with child wrist strap. We have a baby jogger, toddler goes in it with baby in carrier or toddler walks alongside with wrist strap and baby in it :) thoroughly recommend. You can take it all the way to airplane steps and request for it to be waiting for you at the other end!
I literally just posted about Trunkis in another group, and someone said they don’t fit! But I did read online (easy jet website) that the standard size ones do?!
