I remember the BKS days and HS748´s departing for Heathrow, Amsterdam and Belfast but never hourly to Heathrow, though I recall a press release stating how successful the route was and the hope then was for an hourly service! On one occasion and only my second flight ever at that point I booked a return to Heathrow for 6 GBP´s as I was under 21. To my delight it turned out to be a Viscount on lease from Channel Airways.
On another trip back from London the flight almost landed at Yeadon, but due to severe crosswinds we aborted landing and headed for Manchester!
My earliest recollections were Dakotas heading out over Guiseley for London so the Leeds London route has some history so sad to see it apparently ending. Hopefully a Flybe service to Gatwick might start.
