Since Delta began flying the Airbus A220 earlier this year, the plane has proved to be quite an upgrade to the passenger experience on many of Delta’s longest and most premium short-haul routes.TPG’s Alberto Riva wrote about the reasons he loves Delta’s A220s and why he now goes out of his way to fly on them over Delta’s other short-haul aircraft. With a much more spacious cabin than the regional jets it’s replacing, the widest economy seats in Delta’s fleet, spacious fold-down overhead bins on both sides, and a high-resolution, responsive entertainment system, it’s easy to see why he was impressed with the new airplane’s interior.Delta’s A220 has roomy overhead bins on both sides.

Alberto found the aircraft to be amazingly silent.I also found this to be the case when a couple of friends and I recently flew this aircraft from Paris to Zurich on Swiss. Even my friend who is an engineer at a jet-engine testing facility was impressed by how extremely quiet the engines were at takeoff power.The Pratt & Whitney PW1500G geared turbofans are amazingly quiet.

After having only flown the aircraft for a few months, Delta increased its A220 order again this summer to a total of 95 aircraft: 45 of the A220-100s and 50 of the larger A220-300 variant.Between now and September 2020, Delta’s A220-100s are currently scheduled to serve 47 different routes within their network.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.

Especially on the two- to four-hour flights that many of those aircraft are still operating, having extra shoulder room, nice IFE systems and enough room for passengers to bring full-size carry-on bags on board will be a welcome change.
