I do understand that time have changed when one compares the old fashion "state owned" airlines and the new wave of LCC operators. Companies like SAS have heavy and expensive overheads all over. LCC operators are mainly simply flying between A & B. You are also right that these operators are now able to offer even better T&C deals in order to get enough pilots for they fast growing business. However, you will usually work harder for your living with them without too much of extra benefits.
One could not even dream of to set up an airline like SAS or other "flag carriers" for todays competitive market. And obviously pilot unions are trying to do their best as long as they can with existing operators. But how long these airlines are able to keep competing is anyone's guess. Aviation start to be a transport job without the glory of the past.
