Hey there - I would definitely recommend Air Help. They are quite professional, answer immediately in any questions you may have and not to mention that the 50 euros per year for unlimited coverage of trips was almost too good to be true. Only 1 disruption during the year and it pays automatically the subscription - up to multiple times. Unfortunately, as predicted, their revenue model was not great for them and they just changed from unlimited trips to.. only nine () trips!! which is quite disappointing to say the least. At the same time, they doubled the price for the annual subscription. So, if you are asking me about if they are professional and correct, the answer yes. If you are asking me about if it was a great deal, the answer is again yes. If you are asking me if now, it worth it, honestly I don't know. (One solution / idea is to register only flights that are prone to delays / cancellations, for example the latest flight of the day of a route that will have accumulate all delays of the delay.) I hope I was helpful!
