Well we know that SAS are reorganising themselves as they’ve suffered in the current climate, and are in the process of disposing 21 of its MD-80 fleet.
It seems that Allegiant Air was in the market for some aircraft, and thus have brought 18 MD-80’s.
These veteran aircraft are currently on the ground and are between 19 and 25 years old, so they’re easy money for SAS to make with a total sale value of 200 million Swedish Krona.
This move sees Allegiant boost its MD-80 fleet to 52 units, and SAS reduce its MD fleet to 24 units for intra-Scandinavia use (although knowing SAS, they’ll be be on Intra-Europe routes faster that you can think)
