I have this carrier for just transporting to the vet, etc. Works well across the board, though I do want to get the larger model for Rowan. I love how light it is and how compact it stores. However, the protective film was sewn into the seams and that made it quite the hassle to peel off cleanly. That's my only complaint.
For long drives, I got my hands on an old King's Cages finch breeding cage, but I haven't actually been able to put it to any use, yet.
I wanted the largest cage I could possibly fit in my car and this thing spans the entire back seat, with the added bonus of its solid sides serving to both keep direct sun off Marii and to contain his mess from getting into the cushions. He went on a handful of roadtrips with me before 2020 and I was anticipating more, but I'm sure you know how that story ends. Eventually I want to replace the front panels with something more practical and without the stupid guillotine doors, but that can wait until it's at least feasible to travel again.
I don't have any proper hotel cages for my parrots as I just leave them with the bird sitter when I travel.
