Lars Thykier , the CEO for the Association of Danish Travel Agents and Tour Operators states:

" I would like to encourage all airlines that want to survive in the long run to make sure that their fleets are as sustainable as possible at all times. Because consumers are going to have higher demands on future air transport, including low or no generation of CO2 pollution, and a minimal amount of noise. Only by investing in air transportation that do not cause pollution will the airline industry be able to survive as a transportation product."
