Having to pay for your bags and meals are actually good for consumers and overall environment.
If passengers are forced to pack lightly because they have to pay extra fees is actually a win-win-win for everyone. Plus it is less discriminatory because my airfare is not subsidizing someone else abuse of the system.
Same goes with food. I want the option to not pay for the shitty airline food.
The daily and seemingly random price fluctuations of tickets are much larger than the cost of meals you'd save, basically noise.
