Ryanair = Southwest!
I can't see it happening somehow. If EI and others can't make money on the low fares they have I simply don't see Ryanair doing so.
Can they improve aircraft utilisation I doubt it on long haul. Would they offer a business serviceor Premium product doubtful. Flying 737's in Europe holds more potential for the time being anyway.
Ryanair are good at winding people up though just look at their current advertising.
