Delta Air Lines (DAL) achieved the top score overall, a significant leap from its sixth-place spot in last year's list. The Atlanta-based carrier got top marks for the fewest canceled flights and most improved customer service.

The worst offender for mishandling luggage is Southwest Airlines. But the saving grace is that the airline charges no fees for the first two bags unlike its competitors, said Hobica.
As a result, he said, "they handle the most bags."
