What is an example of a day in the life of a commercial aircraft? Do they fly back and forth b/w city pairs? Are the same aircraft flown at the same time on the same day every week? Can someone explain the elaborate system of aircraft allocation?

Well it really depends. Here are 2 routes for example.
IAH-AUS - 733
The 733 will fly probably up to 6 routes per day because it will fly shorter distances and is easily maintained. It is meant to let pax board, get in flight, let pax off, and let another load on very fast. Planes like this include the A319,A320,A321,717,727,737, and 757.
The 772 will take a lot more money to keep up and thus, fly less routes per day. The 772 also flies the long haul routes and thus that route pretty much occupies that plane for the day. The plane is prepped before departure for hours by hundreds of people all together including ground crew, cleaners, mechanics, etc. Then pax board. Then the pilots check everything, etc. Then they take off for a long haul. Usually (like with CO at LGW) there is a flight from LGW-IAH shortly after the IAH-LGW route lands. It is not the same aircraft usually. Usually airlines keep the plane that flew that route earlier say IAH-LGW the day before, to fly LGW-IAH the next day, so the cycle continues. CO at HNL is an exception. CO used to keep DC-10s in hangars at HNL and after a flight, they would get fully looked at until the plane was 100% okay, then it would fly again. Of course, at hub airports, like IAH for CO, aircraft can be brought in and replaced easily. After the longhaul flight, the aircraft is looked over for stress, etc. Hopefully this answers your questions.

Your example is incorrect.
CO flying to LGW is an exception because CO have a maintenance contract with BA at LGW. The aircraft arrives, gets an overnight check and departs the next day.
Normally, a single aircraft completes all legs of a longhaul flight.

yeah- It all depends on the route - the a/c and the distance. A flight abroad will probbaly just do that route and come back.. with maybe a short hop the a/c did before hand. Or You can have for example, I know of some Delta 763's/757 that will go LGA - FLL - LGA - ATL - CVG in one day. then the next day CVG - LGA - ATL - RSW. So the a/c is different each day. And then there is always the factor of maintnence and on time scheduling.

In the case of a CO 772, a typical routing for two calendar days could be NRT CO6 IAH CO34 LGW CO35 IAH CO10 CDG.
A CO 738's normal day could be SEA iah TPA iah LAX ewr MCO.
It is normal for one domestic aircraft to pass though the same hub city two (or more) times in one day. But it's rarer for any given plane to visit the same non-hub city twice in a day.
There are always exceptions of course: CO only has two 753s in service so far, and these are currently doing twice daily EWRFLL/MCO round trips.
