Zinc Flyte Mini or Samsonite Dream Rider or Trunki?

[Niye]

Hi 👋 We're flying long distance in Nov and DS will be nearly 2. Was thinking of getting him his own suitcase, one which could also be helpful around the airport. He won't go in pushchair anymore and enjoys walking but but little legs will tire. Can't work out which of the three is better. Each has its own merits. Wondered what your experience has been with any of these products please? Thanks in advance 😃

Has anyone taken a flyte scooter case on a TUI flight recently?
We’ve bought one as an upgrade to the trunki now my daughter is a bit bigger and it’s deeper than the dimensions for TUI hand luggage.
It’s purpose is clearly to take on a plane so can’t see how it wouldn’t be allowed but didn’t want to have a meltdown and charge at the airport because we had to put it in the hold. Thanks!
