There were several articles today about United Airlines reducing the cruise speeds of their aircraft as a result of spiraling jet fuel prices. Other airlines were attempting to reduce costs by lessening the "tankering" on North Atlantic routes. Since several aircraft are already flying at optimum LR speeds (B-757/767 Mach .80 B-777 Mach .84) how slow are they going to fly them?

Simply lowering cruise speeds won't offer any cost savings by itself - there are many other factors that come into play namely connecting passengers, crew, aircraft utilization etc. These factors are already taken into account by the flight planning department and they make the decision on route, cruise speed, desired flight level etc. At AC for example, it is not unusual to run the 763 at M0.83-.84 transatlantic if they are running late or have pax with tight connections.
So does this mean essentially that the flight planning process has been changed to strictly give preference to saving fuel?

Continental are tankering on every route possible, not just the North Atlantic. The north Atlantic only accounts for a low % of the total flights, where as the rest of the network is thousands of flights.
Tankering saved Continental 1.2 million last month. It is something they are working hard on these days.

I taking a guess here,
I'd take it that "Tankering" is an airline operating a flight taking a full load of fuel in order to avoid the higher fuel costs in other countries. I'd also the guess the same for return trips from places that have lower costs.
