My closest is the "delight" of NCL. However, prices and all, it was just last week I returned through LBA with Jet2. The Wednesday morning flight down to ALC and back the following week. Other than a Go Around with the weather on return (to which I must say the crew handled perfectly), as soon as the plane was on the blocks the stairs were there, straight in and up the escalator, and through the border in no more than 5mins. Reclaim certainly less than 10. It really must depend on the handlers - in my case I must say the same, self-handling was spot on.
Leeds' facilities really aren't that bad - compact yes, but grim not at all. The terminal was clean, plenty of windows on the way through and down to the gates. Must have been some time since you were last through
