Hello All,

Per planespotters.net data, the Airbus A220 commercial passenger fleet reached an important milestone: it overtook the Embraer ERJ in in-service aircraft (447 vs. 446). This blog post compares both fleets.

Differences under similar macro statistics

Both the A220 and ERJ fleets have similar operator concentration statistics, with an HHI of 10% in both cases. However, there are far more ERJ operators than A220 operators (49 vs. 21). The largest variant for both families (A220-300 and ERJ145) accounts for more than 80% of in-service aircraft.

Nine airlines operate 10 or more A220s (Delta Air Lines 81, JetBlue Airways 56, AirBaltic 51, Air France 50, Breeze Airways 50, Air Canada 40, Swiss 40, ITA 27, and Korean Air 10), vs. eight for the ERJ (Piedmont Airlines 91, JSX 75, CommuteAir 64, Airlink 27, Contour Aviation 25, TAR Aerolineas 12, Loganair 11, and Westair Aviation 11).

North America dominates in both cases

US carriers are the largest operators of both families (Delta and Piedmont). The table below shows the share of operators by region:

Region	A220	ERJ
Africa	3	24
Asia Pacific	4	1
Europe	41	4
Latin America	0	8
Middle East	1	3
North America	51	59
Total	100	100

Share in percentage

Both families are popular in North America. The biggest differences are in Europe (where the A220 is popular but not the ERJ), Africa (where the ERJ is popular but not the A220), and Latin America (there are some ERJs, but airlines prefer the Embraer E2). Both families are rare in the Asia Pacific and the Middle East, where airlines prefer larger aircraft.
