Slightly OT, but MCS is often a terrible value compared with paying $30 for an exit row seat one row ahead of the MCS exit row. On longer flights you'd have to buy hundreds of dollars worth of food to make MCS worthwhile. The only difference in the seating is that the first exit row seats don't recline much. If I have a window or aisle in one of these exit rows, I decline the MCS upgrade, which is free for me because I'm Elevate Silver, because I'll usually end up in a middle seat and the value of the free food is much less than the middle vs. window/aisle.
