I've read numerous comments about Ryanair's "unsustainable business model" in this thread, and how they are about to go bust.
Quoting from Michael Winner's paragraph in today's paper:
British Airways loss over 12 months: sterling 401,000,000
Virgin Airlines estimated profit same period: sterling 68,400,000
Ryanair's estimated profit same period: sterling 260,000,000
Unsustainable business model, anyone ?
