For sure is there a market for unbundled fares, but who do want as your customer? The one who only buy the absolute minimum for his needs? Or the one is willing to pay a certain amount to get a full product. These new fares are only a price hike for the later.

Give the fact the earning points will be harder and also X% of the orignial customers are going for the light fares and others will go with different airlines, there won t be a Platinum Lounge in HEL for very long (my guess) - and paying a hefty surcharge for normal lounge would also make the new fares less attractive.
