There are also some other reasons why people are disappointed. For example, if their expectations are too big or even legitimate, but unfullfilled. Like here in Finland. It's pointless to cite you the Finnish-language texts, but I'll translate some opinions from travel forums (from last weekend).
"There is probably no other country in Europe where Ryanair are so slow to develop (as in Finland). They came here in 2003, still just one airport and only 8 routes (from/to the country). To Poland they came two years later; look: 8 airports, 70 routes already..
And in another thread:
"We want them in Turku
"We want them in Helsinki
"Helsinki? No way. They couldn't afford the high airport fees in Vantaa.
And here is a good point of the discussion:
"They will certainly refuse to pay such fees here. But you know what? It's actually one of a very few airlines that could afford to pay these fees. Contrary to many others.
