We do protect our EMS seats and those customers who have paid extra to have the space and early boarding. I just had an issue the other day and I double checked our policy and our policy is to politely inform the customer who sat in the EMS section w/o paying that these are premium seats and that they may sit there is they would like however there is a charge associated with it. I am always polite with the customers as some just don't know about it and I try to offer a different seat to them as many are looking for 2 seats that are empty so that they can spread out and i don't blame them and usually I can help them out. That being said, I am very protective of those seated in our premium seats. You have paid extra to have the ability to sit there and i'm going to make sure you get the full worth of those seats.
