Looks perfect to me. Cheap enough that you won’t be devastated if the airline breaks it, but functional for the holiday.
The only thing to look out for is the recline. Some of these styles don’t recline at all, some recline a bit, and some go flat. I wanted one that went flat, as I often fed the toddler early, went for a stroll to get them to sleep, and then DH and I could have a relaxed dinner while they slept in the pushchair. Lie flat helped this.
