Best and Worst Airlines in the US

my favorite Virgin America cabin

Based on Airline Quality Rating (AQR) report, here are the best to worst airline in the US:

1. Hawaiian Airlines 
2. Air Tran
3. JetBlue
4. Southwest Airlines
5. Continental Airlines
6. Frontier Airlines
7. US Airways
8. American Airlines
9. Alaska Airlines
10. United Airlines
11. Delta Airlines

Of the 11 airlines listed above, I've flew with Air Tran, JetBlue, Southwest, Continental, US Airways, American and United. Based on my personal experience, I have to agree with this report. In fact, I like Virgin America too, but they're not on the list, wonder why.
