Talking about the bottles of water and cost drivers, here at AF, there used to be a time when recourse to such practices as (very) slow taxi and systematic TOGA thrust take-offs would get messages across. No strikes. No media. No
PR. Just engine maintenance reports of costs going through the roof.
VERY efficient, I can assure you !!!
Most cost-cutting actions can be swallowed in these difficult times. I find some are like swearing in kiddengarden and probably require swift and affirmative reaction.
