No. An examination of energy use quickly confirms it's nonsense, along with the formation flying rubbish! I have no wish to be 'kangaroo hopping' across the Atlantic for 8 hours thankyou. The fuel burnt trying to assemble a load of airliners into squadrons, or finger-four groups, will far outweigh any supposed savings. Then they will occasionally bump into each other leading to masses of holidaymakers for Orlando falling into the Atlantic at 30W, or whilst making up formations over Redditch. Redditch doesn't want it, pilots don't want it and we don't need to save fuel that much!
There's plenty. They're finding more and more of it- it grows in the ground you know.
