A few days ago I read an article in BA's onboard magazine about a twice-daily flight up in the Orkneys that's scheduled to take only two minutes! Anyway, it got me thinking -- if that's the shortest flight in the world, what's the cheapest? I called BA, but the rep on the phone was annoyed by the question and couldn't give an answer. Where could I find out? I don't care where the flight begins or ends, but it needs to be eligible to accrue frequent flyer miles in a major program, and it needs to fly frequently enough that I could fly several round trips in a day. (Executive Platinum on a shoestring budget, here I come...)
