Each year the website The Points Guy comprehensively examines U.S. airlines, crunching data in everything from on-board amenities to route network, on-time performance to value of frequent flier programs and more.
The verdict: Delta is No. 1.
In a special report this week, TPG ranked 10 U.S. airlines on 11 criteria, drawing scores from hard metrics such as canceled flights, customer satisfaction and percentage of customers involuntarily bumped.
Concluded TPG: "Delta was the big winner, with 92.7% of planes arriving on time, the largest network of lounges and cities served, and several other strong suits."
Delta beat out Alaska Airlines for the top spot, with Southwest No. 3.
Scott Mayerowitz, Executive Editorial Director at The Points Guy, told Forbes, which covered TPG's report: "Delta was ahead of its competitors in some key investments, and that is reflected in our rankings."
