Cost increases
It seesm some are suggesting that the low cost model has had its day due to fuel costs, taxes, capital costs etc. Clearly cost is all relative. For example, if Ryanair is £50 and BA is £100 and costs rise 20% then Ryanair is £60 and BA is £120 then Ryanair is still low cost. Even if the % rise hits the Low costs carrier more and it becomes £75 to BA's £120, it is still the low cost.
The point is rising costs hit all the airlines
