It's wonderfull to say LCC's are a great innovation and it's gives you more money to save on the land content of your holiday.However,how many $10 fares do you think each aircraft has?
Have you tried to fly at short notice on our LCC's? You might get a fright at the ticket price.As well it might be OK to travel an hour or two but how would you go flying to London or LAX on a LCC?
The same applies to Tiger and the news that they will charge less than $10 to fly Perth to Sydney.Initially there might be a large number of seats at that price but the airlines could not continue to do that.
Another aspect is the profit generated by LCC's.If mother QF wasn't here would J* make a profit or would it be more like it's sibling J* Asia.
