Having originally envisioned the co. to operate between N. Ireland and England; The name ‘OneFifteen’ actually comes from the flight time between Belfast City Airport and Southampton Airport. My drop off and landing points. (1h15m) But not only that. I was born in ’75 which in minutes is in the same as the flight time :1h 15mins. Want more? well, there’s an incredible coincidence involved but you’ll have to ask me ;)
