Didn't look in detail but fair enough.
If you do the Maths with an aveage of 50% loads during summer (we know it was up to 80) and an average of 700 passenger (based on 50%) per week with fares averging 100-150 return VLM pulled in up to 100,000 per week. Possibly closer to 150,000 peak season.
Easily to see lot of money to be made.
