BA has also ordered its pilots to use only one engine while taxiing around airports. Both BA and Virgin also try to use 'continuous descent' when landing, so planes glide smoothly down.

This scares me. I can understand and agree with the idea of adding 10 minutes to a flight to save fuel, but letting bean counters tell professional pilots how to land a plane has high risk of disaster. Pilots will be too busy looking at the fuel gage to pay attention to landing the plane safely.

so planes glide smoothly down

Uh oh. Beware of the word "glide" when it comes to fuel-saving measures.

Nothing to worry about, they are just starting to descend a little sooner to trade altitude for distance. It’s like letting off the gas in your car well before a stop light and letting the car slow its self.
