A few years ago (oh, actually a few centuries ago)working at Gatwick, Laker was running a "Skytrain" to Kingston< Jamaica. Also, just opened was a mono-rail to the North terminal. Sweet little elderly West Indian couple - checked in for the flight. Check in clerk said "Now, get the "train".

Yes, (and this is true - I was working in Ground Ops) they were eventually found at East Croydon, having been sold a ticket by British Rail to Kingston, looking for the "train to Jamaica".

Have a good gig!!
