Strange you should come up with all these great revenue enhancers when we are actively looking for means of increasing the ancillary revenue and saving on operating costs.
One of the issues under consideration is charging the equivalent of "corkage" on the food and drink you bring on board as we have to pay to have it removed: think of it as your contribution to the environment rather than a charge.
The other one we are critically examining is the introduction of a "green charge": it has nothing to do with the environment of course, but since you lot love to whine about "hidden charges", we thought that a charge for flying Irish as a "green charge" would give you endless hours of entertainment. Aer Lingus may also introduce this charge.
Our efforts also extend to reducing the costs at arports: we are now carrying metal trays to asssit in in the speedy disembarkation of passengers of reduced mobility as the lift off can often be time consuming and traumatic, not say expensive.
