There is no benefit to Ryanair in operating 2 types of aircraft with 2 types of workforce on short and long haul.
The choices are to keep the 2 entirely separate or to eliminate Aer Lingus.
Is there any benefit to Ryanair in retaining the Aer Lingus brand which competes against it on it's own doorstep?
Solution?
Sell the LHR short haul slots; bmi, Virgin and the US carriers will fight it out for them.
Stop the transatlantic routes and return the 330s; return the short haul Airbus fleet and replace it with 737s.
If the pilots and cabin crews won't accept Ryanair T & C's close the whole lot down.
Result? All the Dublin slots passed to FR for expansion, no competition, IALPA left with no boll*cks and the IAA at gunpoint.
