Beginning of the end for multilateral interline?

[PAXboy]

Thanks ExXB for the more detailed explanation. My experience in commerce tells me that:

• Company A: perceives they can save money by a certain action and break with the past.
• Company B: follows, being 'relieved' that someone else has broken the line first.
• Companies C~X: follow.

Wait for between 10 and 15 years.

• Company Q: sess the possibility to introduce a feature that will bring a customer service advantage. They promotes it as if it had never existed before
• Company J: follows, not wanting to be left out.
• ... ... ...

The cycle continues ad nauseam.
