Befree - think you are slightly missing the point here. the average fare will not be £812 as not all fares will be sold at the sale price level as like the low cost airlines prices go up closer to departure. If average fare is £100 higher (perhaps 10 passengers a flight book flexible tickets at £1500+ and a number of others book the standard fare) per sector makes quite a big difference to the numbers. If you assume that Ryan/easy average fare is the same as their sale price (£1-10) then under your analysis they would be doomed to fail as well.
Second reading the statement the average cost per sector has gone from 65k at time of ipo to 75k today .....not the huge increase in a 95$ oil world that your past posts have predicted predicted.
Third management stated in release that they expect to make a profit before tax in March....not bad for an airline that has only been going 15 months in a season(winter) when most other airlines (inc successful ones like easyJet) lose money. Also being a PBT figure this will include all head office/marketing and other general overhead costs and is not just breakeven on a per plane basis. The directors would not have put this statement out if they were not confident in delivering on it, as not worth getting in trouble with FSA and like for knowingly misleading the market.
Anyway we will see either way in the next two to three months. However I suspect that with 5000 bookings in last week alone, a strong brand and differentiated product and a cost base materially lower than the legacy long haul airlines and a backer with deep pockets and a record of making money (Reuben Brothers) SilverJet looks more likely to be successful than not.
