I heard about a new travel related startup based in Seattle this morning on John Cook and TechCrunch -- InsideTrip.com. InsideTrip is founded by Dave Pelter.

Quoted: InsideTrip wants to help you find and purchase the tickets for your next trip. However, instead of focusing entirely on surfacing the cheapest flights, the service intends to help you identify those flights with the highest levels of quality.
...
Quality is measured by factors spanning 3 categories (speed, comfort, and ease) and addressing 12 so-called “pain points” (such as number of stops, security wait time, legroom, aircraft type, connection time, and gate location).
