Take for instance this find over at the blog Boarding Area, which recently dug up some old ads from between 1953 through 1970. That’s when United Airlines offered flights for “men only,” where wealthy businessmen could enjoy complimentary cigars, cocktails and a full-course steak dinner in the exclusive company of other men (besides the stewardesses, of course).

According to Boarding Area, these flights were operated in two routes, New York to Chicago and Los Angeles and San Francisco. Flights would leave at 5 p.m. in each of the four cities, six days per week, excluding Saturdays.

Here’s how United’s ad copy pitched it:

Relax after a busy day on this special DC-6 mainliner flight. You’ll enjoy the informal, club-like atmosphere. Smoke your pipe or cigar, if you wish, and make yourself more comfortable by using the pair of slippers provided . . . take off your coat, and stretch out in a deep, soft Mainliner seat. Or, enjoy congenial company in the lounge.

Take advantage of may special services on this flight. Closing market quotations are available and you favorite business magazines. If you’d like do some some work, your stewardess will arrange a table for you.

Eat your heart out, Don Draper.
