Buy 2 seats!

Look if you want to keep making the seats more and more narrow, you have realize that some people don’t or won’t fit. When I buy a ticket, I expect that my seat area has only my body in it and I fit fine. If someone’s fat rolls or back fat are over the arm handle into my space - something needs to happen! I’m tired of this and it’s all to common. Why don’t you set up a feature where we can enter the flight number and seat number of the obese offender and if they are reported more than twice they will be flagged so if they try to buy a ticket- they are warned that they must also purchase the next seat. You spent millions buying smaller seats, now you need to deal with this.
