The obstacles to fuel-efficient tight formation flying are the adverse effects from weight dependent vortices from the wings of the lead aircraft. Vortices are a function of weight and commercial airliners are substantially heavier than all other aircraft that have attempted close formation flying. Conceptually, the benefits are considerable and long range travel could be substantially more economical with cruise fuel savings up to 40%.
