Ryanair CEO Michael O'Leary is considered eloquent. Even if he has played less Punch and Judy in recent years, he hardly ever saves with criticism of airports, authorities and competitors. He is also occasionally active as a "prophet" and predicts bankruptcy for other airlines. Seldom was he really right.

During a Eurocontrol event in Brussels, the Irish manager made another verbal blow. This time he focused on what he saw as the bureaucratic European Union. This is supposed to be the reason why there is still no uniform control of the European sky. There have been repeated advances for Single-Sky, but so far these have always silted up.

According to O'Leary, more efficient flight routes would mean that about 20 percent of the aviation fuel could be saved. It follows from this that carbon dioxide emissions would also decrease. With more efficient control of the airspace, according to the Ryanair boss, the proportion of delays could be reduced by around 95 percent. However, the bustling Irishman did not mention that the vast majority of unpunctual departures are not due to air traffic control, but are homemade by the airlines for various reasons.

It is hardly surprising that Michael O'Leary is not a fan of the proposed taxation of kerosene. A few weeks ago he admitted in a media talk that took place in Vienna that he assumed that it would come and that we would have to come to terms with it. He has high hopes for so-called SAF fuels.

The main criticism of the Ryanair boss is that he assumes that the tax revenue from the taxation of kerosene will not be invested in the development of alternative propulsion systems. SAF fuels should be made tax-exempt or at least favored so that there is an incentive for airlines to refuel. Ryanair wants to convert at least 2030 percent of its annual requirements to alternative SAF fuels by around 12,5.
