Answering a question posed earlier in this thread by 0524, you might be thinking of Highland Express. They were a one-747 airline that launched a JFK-GLA service in the late 1980s. Lasted less than six months.
Alternatively there was British Caledonian, a really lovely airline that competed with BA using Gatwick as a hub and adopted Scottish tartans as a brand motif. I believe they flew JFK-MAN for awhile, but I'm not sure. BA ate BCal in July 1987.
