Good analogy.
This clip is about recent European airline bankruptcies. It shows how euro airlines have seasonality pressures on cash flow more than those in other world regions.

I can understand the arguments for seniority IF airline businesses were stable and you could count on them for a long term career. It was probably ideal when it started during the days of a few state run flag carriers.
But now in Europe we‘ve had many airline failures, and there is little or no bankruptcy protection such as in Chapter 11 in USA. This is the reason I find it hard to agree that seniority is the best system for us. It’s not a case of whinging about “not fair”, it’s about having options for yourself when things go wrong or life goals change.
