Eeeeek! That’s bad but remember that being efficient doesn’t always fall to the a/c that burns the least amount of fuel or pays the least for its FLT crew.

Now if you’re talking about only moving 37 PAX then yes the CRJ/ERJ/737/A320 and all others are not as efficient as the Q. Can you imagine how inefficient a 747 would be with only 37 PAX on board going between DEN and DUR?

Now let’s think about moving 30 or 130 or 230 PAX and how much of a premium or not are those PAX willing to pay? Many other factors must be included; do you see what I’m getting at?
