This morning's AJC has an article about airlines using fewer RJs. Here's the link:

Interesting info:
A Delta 50-seat CRJ-200 made by Bombardier takes 19 gallons of fuel to fly each passenger 500 miles. Fuel usage drops to just 7.5 gallons per passenger on Delta's 160-seat MD-90s over the same distance.
So while the bigger jet burns more fuel overall, it's more efficient.
While I knew larger jets are more efficient in this regard, the actual numbers are interesting to know. Thought others might find it interesting, too.
