Embraer and SkyWest announced a deal for 25 E175s. Ten of these are 76-seaters for Alaska Airlines. The other fifteen are for Delta Air lines but only have 70 seats. The Delta aircraft are named E175 SC. SkyWest notes the SC can be configured to add the extra six seats.
The Delta seating is interesting because their current E175s have 76 seats (12/52/12) as allowed by scope clause. Delta’s scope clause limits the number of 76-seaters. These 70-seaters are to replace the ExpressJet aircraft that will no longer serve Delta.
