Air Australia
From Tardis Wiki, the free Doctor Who reference
Air Australia was an airline which serviced at least Heathrow Airport. On the day that the Fifth Doctor, Nyssa and Tegan Jovanka landed at Heathrow in 1982 — immediately following Adric's death — the airline had to temporarily suspend operations due to inclement weather. (TV: Time-Flight)
Behind the scenes
Though there has been an Air Australia in real life, it did not exist until the 21st century, which means that this Air Australia must be regarded as wholly fictional.
