These four-engined flying boats were used primarily by Pan American Airlines in the thirties. The "Alaska Clipper flew round trips from Seward, Alaska, to Honolulu, Hawaii. Service was superb, with one flight attendant for each four or five passengers, fine wines, sirloin steak dinners, and so on. Seats were spacious and comfortable, and decor was top quality.
