Per jrl767: 4. Fill in the blanks on this 1964 advertisement: A ______________ is a quiet bird. So quiet you can think. Or talk. Or listen to the Champagne fizz. Or even sleep, if you don’t mind missing the party. If you demand the full Audubon definition, a ____________ is ____________’s own special version of the great new T-tail ___________ fan-jet.

As long as we’re on the subject of color, how about this ad being color-focused: Yellowbird, Northeast, Boeing 727

Nice guess, J - as with YVR's, it fits nicely into the script. Alas, the airline in question was not Northeast, however. But - the aircraft was a 727. And - the airline did fly to destinations where sunshine played a big part in visitor enjoyment.
