United Airlines
No one likes big airlines.
The latest survey results from the American Consumer Satisfaction Index (ACSI), which looks at hundreds of big companies, show that telecom companies, airlines, and social media sites are most likely to frustrate people.
In defense of these industries, no one notices them when things to well, but people get outraged when they lose service or get stuck for hours at an airport.
On the other hand, these industries often have customers locked down and don't have to worry about making them happy.
