I am looking to fly my pets (a labrador and a cat) to the UK next year from Brisbane and have been collecting some quotes. And I have to say, I have am a little confused by pet carriers - I have been quoted different sizes by different companies. Jetpets in particular have said I should use a PP90 crate for my labrador, which seems quite big... And Aeropets recommend a PP60, which seems only just big enough... These are both recommendations based on renting/buying the crates through them. Does anyone have any experience with crate sizes? I'm starting to think I should buy one and use my own judgement on sizing.
