Since I started covering aviation about a year ago, I have been impressed at how devoted some travelers are to their favorite airlines. Many fliers love airlines as if they’re sports teams. (I get the connection, as both airlines and teams tend to disappoint a lot of people.)
This means, of course, that there is a considerable market for all types of memorabilia. See that American Airlines advertisement above? You can buy it on Amazon for a mere $23.95 plus shipping.
Incidentally, can you imagine any current airline running an advertisement bragging about its engines?
