The Best and Worst U.S. Airlines in November

Fewest Customer Complaints

Southwest — 15 total complaints, 0.16% per 100,000 enplanements

Southwest has long been king among airline customers for its customer service, and passengers still love LUV. Keep a close eye on the impact of a number of new fees on customer satisfaction; Southwest has added a $40 early boarding fee for passengers who want a guarantee that they will be among the first group to board the plane. Still, as long as “Bags Fly Free,” LUV should retain its popularity with frequent flyers.
