I flew my dog from Thailand to Uk, was really concerned too. However on picking her up she was fine,excited to see us and happy to jump back in the crate when asked. Worst part no one tells you about is jet lag for dogs, getting woke up at 2 am by a dog wanting walks and breakfast is fun.Took about a month before she adjusted to new time zone.Also be aware of new allergens she hasn't been exposed to particularly grass seeds etc, to start with wash her paws after a walk until her body adjusts.
If you can arrange it get a t-shirt towel or something similar, with the scent of who has been looking after her in the crate.Don't worry about the flight so much, the flight manifest is really strict regarding temperature, placement of crate etc.
As for quarantine, I'm told although it's not the palace we create for our dogs, they are well cared for.10 days will soon go quickly, then you can have your mate with you and get her used to new surroundings.
My own dog is now in UK, as she failed Enchila test, but fingers crossed she will be with us in Cairns come the new year.
