You nailed the problem! 20 more seats per flight and we wouldn't be having this conversation. And this is not just about PIT...every employee should realize that their non-rev 'travel benefits' aren't worth anything, because you can't use them. Tell prospective employees to go to work for Delta, at least they have big airplanes and are not afraid to use them.
The crux of the issue is that the company doesn't care about the commuters. Actually it is fairly obvious that the company does not care about their employees at all. They have been told they are 'cost items', not human beings.
The company could care less about you - that is the prime directive every employee should have engraved on the back of their eyelids.
The truly frustrating thing is that when the co. closed PIT, they knew they'd have 1400 commuters and they gave that zero consideration, putting all the responsibility on the backs of the employees. Then they downsized aircraft and reduced frequency. Oh, by the way, all in a down real estate market - with no provisions for house purchase or moving expenses. Sheesh.
