Last week I saw a Mesa (Skywest?) 175 RJ flight from the Terminal B RJ gates to LGA. I was somewhat surprised scope limitations did not prohibit that route from being an RJ. Is it allowed because LGA is technically not a Hub? Or can they do anything they want with RJs so long less than a certain amount are flying?

Either way I was frustrated it was one less New York overnight in our system, and my 50 seat RJ to podunk regional airport is often broken, late, or weight limited forcing me to buy the one way rental car home. I wish the 175 was going to my podunk regional, not LGA.

Rant over...
