Here's an easy way to think about what you're thinking of doing... You are going to be paying the pilots wage, plus at least twice the cost of your weight as cargo on the plane to be sitting in that seat.
Key lime then doesn't have to worry about paying that pilots hourly wage for those flights and they get to make some more money for doing nothing...
Having you in that seat is pointless and just hurting this industry even more. If anything there should be someone getting paid to be in that seat. Not having the person in the right seat paying the left seat guys wage and more.
