I know this is a sweeping generalization and all… But I’ve been a commuter my whole airline career. I regularly Jumpseat on AA flights and have only run into 2 odd balls out of hundreds if not thousands of flights. I’ve jumped on Delta a couple dozen times and I’ve had either odd or downright awful experiences 5 or 6 of those. Most seem to be centered around the 75/76 fleet. All the times I’ve been on the jump of the 717, 73, or old Mad dogs it was a good experience. So I dunno, Delta sure seems to have some odd balls in proportion to other carriers.
