Outside-airport traffic aside, the flight was a fantastic experience. The plane was incredibly comfortable compared to just about every other jet serving the 100-seat market, including the Bombardier CRJs and Embraer RJs of yesteryear.
While the A220 is meant as an eventual replacement for the larger of these, its range and efficiency give it a niche that's more in between the regional jets and the mainline narrow bodies, seating just 100 or so passengers, but capable of flying coast-to-coast.
That potential is evident in the fact that Delta just scheduled the A220 for a daily flight between Atlanta and Seattle. While a flight that long on a regional jet would be unpleasant, to say the least, the A220 should be a perfectly comfortable ride.
