the metrojet will cease svc the begin of the new year. for nov you should be fine. you went thru schedule changes. this is with all the carriers it happens on a quarterly basis. this si what happens when you buy a tkt so far in advance. if you do not like what they put you on then tell them.
so far so good on flights from pit. this is the way it was explained to me...they will use more feeder flights into the major hubs, pit,clt,phl. so these 3 cities should still be the same with flights...its the smaller cities that will get cut and they will use more express to feed nto the hub. they are utilizing the spoke and hub system more now than ever before. if I could post a diagram here it would make more sense.
