Great question Maren and I'm big on Airport blogging partly because I have an Airports blog: www.QuickAid.com and partly because I think we tend to forget that it's about the journey as much as the destination. I've started to *enjoy* longer waits in Airports because they often tell you a lot about the country or region. In Thailand, for example, Bangkok has a beautiful airport with some amazing interior design, shops, and statuary. PEK Beijing is also a new and gorgeous airport that tells a lot about the "new china" in terms of it's size and architecture. I think travel bloggers should blog a lot more about airports, helping other travelers find the best restaurants, shops, and experiences in these amazing intersections of cultures, peoples, and planes.
Here's a sample post about an Airport:
All that said I think Airports could do a LOT more to offer information and experiences. For example only a handful of Airports offer the great regional travel information we'd get at a welcome center for a city.
