As said previously, some Comair FAs recycle the cans which DGS throws who-knows-where.
Comair also recycles tired old Delta/NW executives by implementing the unique "Run Comair for a year" program.
Comair is currently leading the way in whole-aircraft recycling by sending a large percentage our aircraft to other Delta regionals.
In conjunction with Delta's new eco-friendly "ComairGreen Initiative", many of the aircraft Comair still has on property are involved in the "It burns less fuel when it's sitting still" Jet-A conservation program.
But best of all, Comair has started a fantastic new recycling program designed to save Gigawatts of electricity (sim time) and thousands of pounds of paper (training manuals)...
The new program allows Comair to fill First Officer positions with already-trained Comair Captains rather than having to hire and train low-time pilots off the street.
It's the green thing to do.
