I believe SN should be offering a premium product for people who can afford it, and a bare minimum product for those who can't, but at rock bottom fares.
A two-classes (or even 3-classes) product: ryanair class, LX-class, and yes, if you want, something in between, some economy premium (economy with flexibility and food).
You will say, SN already has such product, being B.business, b.light and b.flex, but I believe they should take them to the extreme. And take example on airlines that make money.
I'm glad that someone else also feels this way.
I think that SN needs to adapt its hard and soft product to offer a more exclusive business class at more or less the same fares as now and indeed go ultra-lowcost on the last rows of B.light. In-between, they can keep the B.flex as a flexible economy offering, with the possibility to upgrade to business class with miles when available or to the highest milers when the economy class is overbooked.
I think that such a move will have premium people going out of their own way to fly SN even for intra-EU.
This way, SN will be leading the market instead of catching up with it and become the quality carrier of choice for travel within Europe. It's a move that will require significant investments, but I think that the impact on SN's financials and brand will be significant, short- and long-term.
The way I imagine it is:
2 rows of 4 seats on A319/A320 and RJ100, on the Q400's optionally 2 rows of 3 seats.
