Get your management to approve for the first time in it's history, a Union message on the PA to your captive audience...
Fat chance that's likely to happen, in todays contentious management/employee diatribe.
What
is needed (in the USA especially) is realistic ticket prices, to reflect the cost of doing business.
Will less folks fly?
More than likely.
However, this will have a side benefit...less air traffic, less need for more runways/ATC controllers, etc.
The downside?
Junior folks out the door on furlough, and for the ones that remain, slower advancement to the LHS, especially now that the max retirement age has risen to 65.
