Re: Pleasant Hawaiian Holidays and American Trans Air

Does this bring back memories. My first flight over to Hawaii was on Pleasant Hawaiian but my recollection is I was on a Pan Am Jet. Sometime in the Early 1980’s, I flew on a 747 with a Pleasant Hawaiian livery on it. I recall a green and yellow color back then. Are they still in business?
