The 109-seat aircraft, which features wider seats and more comfort in the cabin, took off from LaGuardia Airport and landed in Boston.
The new plane is part of a trend of airlines giving high-paying passengers more room and comfort on smaller jets.
In addition to the wider seats, the A220 will feature high speed WiFi, bigger luggage bins and even a window in the bathroom.
The plane will eventually dominate routes from LaGuardia to Boston, Dallas, Houston and Minneapolis.
