VOY is short for Voyager, my nickname during my inspection days when I inspected/audited/evaluated thousands of hotels and airplane companies worldwide. Also as a Trekkie since over 50 years, it's my favourite Star Trek show.
KAY is merely how you pronounce the last letter of my family name, starting thus with a 'K'.
And here I thought Felix stood for:
Fantastic
Energetic
Likable
Interesting
Xenial
