I am wondering for airlines that have big fleets of aircraft powered by multiple engines types (e.g., BA with both GE and RR powered 777s), if the engine type determines the scheduling of the aircraft for specific routes? It seems here at New York that we predominantly though not exclusively see the VII* series.
Related but unrelated, does the price of the aircraft vary if you choose one engine type over another?

The performance between models is close enough that engine type would only require specific scheduling if you were right at the bleeding edge of the payload/range curve or you were going to an airport that would force you to do a full power takeoff and you have different thrust ratings.
That said, for operational reasons you might want to keep your engines on different routes so your outstations don't have to stock all the tools and parts for both types.

Sort of. The price of the aircraft itself is pretty insensitive to engine selection but the price of the engine varies.

Generally speaking, the RR-powered 777s are used on longer flights to deep Africa, South America, India and Asia/Australia as they are fitted with crew rests. They also serve destinations like YUL and DEN. 777 markets that don't have First class.
The GE-powered 777s are more commonly (but not exclusively) used on routes to the US and Canadian east, Middle East and northern Africa. As well as all routes out of LGW. This is particularly true for the G-ZZZ* registered aircraft as those are original A-market 777s with shorter range and a larger First class (17 seats v 14 on the rest of the GE fleet).
This is just a generality. I don't have the time to go into more detail. Also, nothing is set in stone. The RR-powered 777s are often seen in cities like BOS, IAD and ORD and GE-powered 777s can be seen in India.

Luanda is a GE route. The following are also exclusively RR routes
Seattle (BA049 on days operated by 777)
Quoting BAW217 (Reply 3): The ZZZ* Fleet are used to the Middle East and NE USA only.
Plus Abuja on Wednesdays.
Many flights are operated by both GE and RR powered aircraft and 99% of the time they are scheduled as so. For example, Calgary is a GE route, except on Fridays, when it is operated by RR aircraft. There are a few occasions where, for whatever reason, one type may operate a flight that is scheduled to be operated by the other type.
