6. Which airline had the worst record for complaints?
C. US Airways
The answer is A. United had a total of 162 complaints which worked out to 2.33 per 100,000 passengers flown. Southwest had the best record with just 15 complaints (for a rate of 0.16) and US Airways was roughly in the middle with 66 complaints (1.47). It should be noted that only complaints lodged with the Department of Transportation are counted in this tally; it does not include angry emails and letters sent directly to the offending airline.
7. Which airline bumped the most passengers (from January to September 2012)?
The answer is C. Mesa racked up an "involuntary bumping" rate of 2.49 "denied boardings" for every 10,000 passengers. JetBlue bumped the fewest. American was roughly in the middle.
8. Which airline is the best?
A. Whichever one gets you and your belongings to the correct destination on-time, every time you fly.
That's the only possible answer and yes I do wish I could be more specific!
