I've got a bit of a soft spot for the 7-3s.

So long as you are not caught up in a delay due to tech reasons, i really enjoy flying on them. There's a certain homely feel and smell about them. I don't even mind the toilets either. They are old, we know they are old, however they still do a good job.

Also fair to mention that i love flying on the Comair 737s. They are even older. There is a sort of dusty smell onboard, particularly when you get one with the old fabric seats. Service and quality of the food and wines, both in Cub and Traveller, is superb.
