What do I think?
someone has to pay the $9000 an hour operating costs.
Micheal O'Leary must be a leprachaun if he hopes to have his passengers fly for free
OR
To check your bags in will cost $100 instead of being free
To ride the airport shuttle will cost $50 instead of $10
To stay in the hotel will cost $250 per night instead of $200
The hire car will be $120/day instead of $100.
And to parody the credit card advert,
The look on the punters faces when they find out how much their free airfare really cost, - priceless!!!!!!!!!!!!
