"stepping on others necks" is an unfortunate side effect of the system we work in. Asking someone on a completely different list to "take it for the team" for your(family's) sake at the expense of their own is simply unrealistic.

We all dodder on about how stupid airline management is but is that really true? They created this system and I think they saw it for what it truly is.
