I wish they would just get rid of those planes altogether. They really are garbage. Every single day, 85%(being generous) of those flight have maintenance issues on them. It is NOT rare that they delay a flight for hours, switch planes, only to find out that THAT one is broken also, then switch to ANOTHER plane that they ALREADY KNOW is broken....then, 5 hours after the whole ordeal started, cancel the flight. The other night we had one get 1/3 of the way there only to have to come back. They "fixed" the problem, sent the plane back out, and wouldn't you know it? It came back again!
At some point, you've gotta ask your self "Are we really doing a service to these people by doing this to them?"
It's downright embarrassing sometimes.
