In a bad year for travel, no one airline had a particularly good year. Blame staffing shortages, bad weather and big crowds. Airlines are ranked by seven equally-weighted metrics covering flight cancellations, on-time arrivals, delays, involuntary bumping, baggage handling and complaints. Southwest Airlines landed in the third spot despite December’s travel chaos. That’s because baggage handling and complaint data won’t be available for a couple months. #airline #flights #planes #delta #southwest #aviation #wallstreetjournal #wsj #thewallstreetjournal
