I must admit I was quite surprised at the prices on the ABZ-SEN route. I'm flying back from London in June and I got a £49.99 one way fare to ABZ, when the likes of BA/BE were charging in excess of £90 from LHR, so I'm trying out the LM service for the first time. Having looked more recently the fares do seem to have climbed a bit more, but are still cheaper than the much shorter ABZ-KOI flight that I've also looked at taking.
