I have flown with dogs of multiple ages from 3 months to over 1 year of age...including one flight from the west coast to the east coast without any issue whatsoever. They sleep the entire time. Other passengers are often surprised to learn I have a dog(s) with me.
If you don't routinely use a carrier I would advise getting her used to one.
Happy travels.
