They are getting in quite a mess. Today 3 hour + delays due crew shortages leaving them at the mercy of big eu261 claims? Take a look at the arrivals and departures board.
On the back of the drag curve with pilot numbers? No longer a matter of simply replacing the leavers, but needing to think and anticipate those that are likely to leave. Still they persist with unattractive 50 and 70% deals like hagglers at a boot sale with little understanding of a changing job market.
Intensive in house type training in the peak season? Maybe a bad idea when it pulls valuable resources from front line flying.
Large fleets of older aircraft. Maybe not such great value for money when spending large sums recovering casualty aircraft, chartering short notice stand in cover and propping up the operation with king airs and biz jets shipping crew and engineers about.
