First of all, I am glad KLM finally has an app!!! Basic functionality but it feels a lot like an iPhone interface into the KLM website. Id recommend to take a look at the apps from Delta and Air Canada which are truly fantastic! I am looking forward to future releases with better graphics, more functionality and innovation. Again, glad KLM finally launched an app though (about time!).
