I’m more likely to trust LP’s back of the envelope calculations than the Daily Mails I’m afraid.
Using the DM’s stats would mean that, even a simpleton like me can see that if the cabin is conservatively 20 pax light the flight runs at a loss! And IMO that makes the figures horse hockey.
I’ll add, that the fuel surcharge,if memory serves me right, was an additional cost based on the excess cost of fuel, not the whole fuel bill.
But I’m happy to be corrected
