Even though our flight was very short, it was long enough for me to get a taste of the A220's first class product. Let's just say I'm impressed. The aircraft delivered a smooth and whisper quiet ride while the in-flight entertainment and onboard amenities proved to be top notch.
The A220's economy class experience is markedly better than other Airbus, Boeing, and McDonnell Douglas narrow-body jets. However, the Delta in experience for first class, while present, is less evident.
With that said, the Delta Airbus A220 experience, on the whole, is an absolute triumph.
With a range of nearly 3,400 miles, the Airbus A220 can be deployed on trans-continental domestic flights between cities such as Boston and Seattle. These are flights normally operated by larger narrow-bodies like the Airbus A320 and the Boeing 737. If I had the choice, I'd take the A220 all-day, every day.
