You can get the better service and more room, easily, by simply paying for First Class.
If you are willing to pay as much as people used to do (in inflation adjusted dollars), you can get the same service, often better.
When the airlines were heavily price controlled and regulated, before 1978, coach class subsidized the premium seats. Now the premium (First Class) seats pay their own way, and constant dollar prices tend to be close to what they were pre-1978.
Agreed. We now have the option to pay and enjoy first class, or go cheaper and have less quality service. People should embrace the choice to do either.
