I've been a little disappointed lately with some downgrades to the MCS offerings - first they started charging for certain wines, and then certain snacks, and now they've started carrying fewer items on certain flights.
For example, it used to be that pretty much all the snack items would be catered on all flights, even shorter ones like SFO-SEA. Last week I noticed there were only 3 or 4 snack items available before anything sold out. The know I know for sure was missing was the chocolate truffles.
For the longest time their marketing for MCS just said free food and drink but I noticed only recently they updated to now specify "select food and drink".
