Bedsted,
You are obviously a very good caregiver to your dog and have posted great advice. My dogs get stressed on a 8 hour car ride. Never had to muzzle my dogs, did not consider the need if crated in flight. Just wondering why the carrier may want to and the dangers of doing so. My wife is insistant on placing food and water in the car, they rarely touch it until we meet our destination and sometimes for hours after.
