its also possible the -700s will be parked. the comair planes gojet has are some of the oldest non -50 seaters in DL connection. DL is buying 75 A220s and they have said since the order that they are to replace rjs. why go through the hassle of moving planes when they can replace them that way. one way or another DL will probably park 75-100 rjs over the next 4 years ( unless something changes).
