Had a chance to visit the Dublin Airport yesterday.
Bike lanes and signs directing one to the bike parking facilities were everywhere.
There are even Bike Lanes right up to the hotel entrances!!
In terms of bike friendliness, this looks like an air facility that ranks at the top for bicycle access. I know Portland and Chicago are both excellent in this regard. However, I could not find a list that compares the world's airports. Is there such a thing?
