The airlines are right, pilots should not have to pick between flying a plane that they don't think is safe and having to authorizing refunds for passengers… they should be able to call an airline safety whistle blower line so that an independent safety officer can take a look and ground the airline for not maintaining their airplanes.
Seriously, how can airlines argue against it? They are saying that they will pressure pilots to fly death traps? I think airlines would be ashamed to have airplanes in such condition.
