Yep, this story looks like a cut and paste job since several of these airlines are either history or merged with other carriers!
I agree with the Aero Mexico inclusion, except for Air India and Laker back in the back packing days, I've never had worse International flights than on what used to be Mexico's Flag Carrier when it was Government owned!
I'd question the inclusion of American and United, I've had worse flights on lots of domestic Airlines, especially Delta and US Air!( Im a Million Mile flyer, Retired, but honestly I've only flown once in the past year and that was on Alaska Airlines which was First Rate!)
