AIDAcosma in the ARD Check: Cost Trap and Climate Dilemma in the Canaries?

In February 2026, the SWR (Southwest Broadcasting) scrutinized the cruise giant AIDAcosma for the ARD network. Presenter Johannes Zenglein thoroughly tested the Helios-class ship on its popular Canary Islands route. The focus was not only on the relaxation factor but primarily on the question of whether the ocean giant lives up to its advertising promises. The result is a compelling look behind the scenes of mass tourism at sea, showing that those who book here should know exactly what they are getting into.

Especially regarding costs, a second look at the bill is worthwhile. The tempting starting price of 899 euros for the week quickly turned out to be merely an "entry ticket" during the test. As soon as one leaves the included buffet paths, the cash register rings: whether for specialty restaurants, wellness access, or a simple coffee in between – the incidental costs add up significantly. Including the expensive, cruise-line-led shore excursions, the travel price had almost doubled by the end. The conclusion: Without a substantial buffer in the holiday budget, the supposed bargain trip quickly becomes expensive.

The AIDAcosma also sails in choppy waters when it comes to the environment. While the modern LNG propulsion ensures that hardly any soot or sulfur oxides are blown into the air on either port or starboard – allowing port cities to breathe easier – the NABU (Nature and Biodiversity Conservation Union) warns urgently about so-called methane slip. Since unburned methane escapes, the climate footprint of "Green Cruising" is significantly worse than often suggested. Those standing at the railing breathe cleaner air, but according to experts, the climate is hardly helped as long as fossil LNG is in the tank.

Life on board resembles a floating small town with over 6,000 people (guests and crew). The report makes it clear: Those who like hustle, bustle, action, and efficient travel are in paradise here. However, those seeking peace and solitude will be disappointed. The ship is a perfectly optimized system where density and noise are part of the concept. In the end, the AIDAcosma remains a technically fascinating amusement park on the sea – ideal for sociable people, but a challenge for anyone seeking true silence.
