I very recently heard that Boeing made a hybrid 737-700, the 737-700ER. Just out of curiosity: Has Boeing made more than just the one 700ER for ANA? It is simply a very intriguing airplane to me at least because according to Boeing they put -800 wings and gear on her and then added aux fuel tanks, so in essence it seems to be almost a BBJ but with an airline passenger interior. Maybe this was meant to be a competitor to the A318 that BA uses from London City to JFK?

Just wondering if Boeing made only one -700ER in hopes that the idea would catch on???

ANA has 2.
Don’t quote me but the 700ER designation may be just a marketing name for a BBJ. I can’t find any orders listed for this aircraft under the 700ER designation on the Boeing page. When I look up the type certificate data sheet the 700ER isn’t mentioned.

Boeing 737-700ER

The Boeing 737-700ER (Extended Range) is one of the newest versions of the successful Next-Generation 737 family. The derivative is a BBJ-inspired airplane designed for long-range commercial applications. The 737-700ER has the longest range capability of any 737 family member in commercial service and allows airlines to profitably serve new nonstop, point-to-point routes. The 737-700ER was launched Jan. 31, 2006 with an order conversion from ANA (All Nippon Airways) for two airplanes.

The airplane’s versatility, low operating costs and range performance can serve all new airline business requirements including low-cost carriers that wish to expand their market reach across the Atlantic Ocean and traditional carriers that wish to compete in niche markets such as all-premium-class service.

The 737-700ER has the same aerodynamic and structural changes as the successful BBJ, offered through the Boeing Business Jets Program. The 737-700ER has additional fuel capacity that allows it to fly up to 2,280 nautical miles farther than the 737-700.

The high-performance derivative comes with an option for up to nine auxiliary fuel tanks, giving it a maximum fuel capacity of 10,707 gallons (40,530 liters) and a maximum range of 5,630 nautical miles (10,425 km).

The 737-700ER provides the ultimate in flexibility when it comes to possible seating configurations. The twinjet can seat 48 passengers for premium service; or up to 126 passengers in a traditional two-class configuration.

The 737-700ER shares the same performance attributes of the other models of the Next-Generation 737 family (737-600, 737-700, 737-800 and 737-900ER) such as reliability, lower maintenance costs, lower operating costs and state-of-the-art flight deck systems.

The 737-700 model is powered by new CFM56-7B engines produced by CFM, a joint venture of General Electric Co. of the U.S. and Snecma of France. The engines meet strict international noise restrictions.

Thanks for the informative reply. Wonder if any -700ERs went toward the AEW&C program whereby the cert. data sheets do not reflect a -700ER?

If that is the case, then would that mean that 33879 at ANA is the only passenger -700ER ever made?

Sounds like Boeing needs to push the passenger -700ER more to compete.


The BBJ is known internally at Boeing as the 700 IGW (Increased Gross Weight). It uses the -800 wing, center section and landing gear bolted onto a -700 fuselage.
It looks like the -700ER is basically a BBJ with a lower capacity airline interior and extra fuel tanks. 48 to 126 seats instead of 150ish.
I have no idea how many have been produced however.


Hows this?
