Average fares are hard to compare. For one, LCCs and regular airlines are using different airports and at least the LCCs in europe are only covering certain high traffic routes. I would love to know where they got their numbers from and whether they include any additional fees (airport, luggage etc.).

Also note that "Cheaper airports / landing fees" was calculated in the image to amount to 6% of the savings of LFAs. Only covering certain high traffic routes is a good point, and doesn't seem to be mentioned.
