I think over on the Delta thread they were saying the C series only really out shines on the longer stage lengths.

Air baltic loves them...

21 percent better than the current 73 fleet.

Which compares how to the E-2 series?

Well air baltic claims 57 percent efficiency gains over the q400.. i know.. apples to pineapples..

There is no real world comparison yet.. embraer had to rework the wing in their development.. engines being equal, its certainly going to be a bitter battle.. hopefully the c searies is so efficient mainline will favor them instead of the rjs and this silly regional market can dry up.. i know.. i know..

The numbers I’ve seen show the E2 as closely matching the economics of the CSeries. That’s on stage lengths of about 500nm I believe.

That’s on operating economics alone. The E2s sell for a lot less money than the Cs.

The E2 is cheaper than the C-Series and it is more economical on shorter flights. Longer than 800-1,000NM is where the C-Series shines.

They are optimized for different ranges. If you want an aircraft to fly 2800 miles nonstop it will be the C-series. But if all your flights are 2000 miles or less, the extra tankage is just more weight and bulk, even if it doesn't have fuel in it. The mission defines the economics as much as the airframe and engines do.

The thing killing the 175-E2s is that they are too big for scope but mainline carriers don't want to open the box of aircraft of that size class back at mainline. I expect attempts to renegotiate weight limits for scope from management.

In the end, if they are the most cost-effective for a niche, SOMEONE will fly them in it, be that someone a regional without scope restrictions (Horizon), a mainline carrier (several already flying E-190s), or somebody who has a lot of money and thinks he/she can make more by being more efficient in that niche than anyone else (Amazon Prime Air, anyone?

It's a capitalist world out there. If everybody sees a chance to make a buck, somebody is gonna take it.

Embraer announces orders at Farnsborough
 

FARNBOROUGH: Embraer lines up deals for some 300 E-Jets

17 JULY, 2018 SOURCE: FLIGHT DASHBOARD BY: GHIM-LAY YEO FARNBOROUGH
Embraer has so far at the Farnborough air show unveiled deals covering up to 300 aircraft worth a combined $15 billion.

The deals span both the E-Jet E1 and E2 families of aircraft.

After yesterday disclosing a United Airlines order for 25 Embraer 175s, the Brazilian airframer today announced letters of intent for orders from Azul (21 E195-E2s) and Republic Airways Holdings (100 E175s with an additional 100 purchase rights), along with Wataniya Airways' firm order for 10 E195-E2s plus 10 purchase rights.

In addition, existing Embraer operators agreed to add more aircraft to their orderbooks. Switzerland's Helvetic Airways has signed a letter of intent to take 12 E190-E2s plus 12 purchase rights, intended to renew its fleet, says chief executive Tobias Pogorevc. Helvetic operates seven Embraer 190-E1s and five Fokker 100s.

Mauritania Airlines has ordered two Embraer 175s, while Danish lessor Nordic Aviation Capital (NAC) will take another three E190s.

Separately, an undisclosed customer from Spain has signed a letter of intent covering five E195-E2s: three firm orders plus two options.

"It is hard to argue that Embraer has no momentum when you have these sales numbers behind us," says the manufacturer's commercial chief John Slattery. "Today is about Embraer reaffirming its leadership in the space for up to 150 seats."
