the 220 may be more efficient on longer routes, but most of our fleet is. I think the whole “the 220 only works on longer routes” comes from the fact it was our first modern engine NB and for several years was the only one and we only had a couple dozen of them. Now we have close to 100 220s, 100 321NEOs another 150ish combined more on order plus 100 maxes. Now that our fleet looks like that we are seeing 220s and NEOs on plenty of shorter routes and I imagine we will see the 220 continue to take over flying from the 717.
network will match capacity when it can.
also almost all our 738s are older than our 717s. I believe they will certainly out last the 717, but they won’t be around forever.
