Agreed, the fitting needs to happen before the security.
Clearly outline the seating policy in a huge font, make the buyer check a box etc that agrees to "all guests of airline must be able to comfortably fit in the sample seat. Failure to fit in said seat will result in the immediate refusal of the "individual" from the flight, their ticket will be cancelled and an administration fee equal to the cost of the ticket will be immediately applied, and no refund for the cost of the ticket will be issued".
Yes, I like this. I think that we should start an airline. I hear that SPIRIT is going out of business, maybe we could crowdfund the first "anti-fat express". "We get you there on-time and under-budget because you are human sized".
We could even bring back 2-3 free "check" bags for that weight reduction possibly.
It's better to let that company completely crash and burn. When you buyback company, you assume its assets AND debts. The debts are substantial for Spirit, and their assets are planes that have seen the worst treatment from their mostly nigger passengers, and DEI mechanics.
A new airline crowd fund could work, bringing back free checked bags should be easy when things are run by white people again.
