Nothing could be worse for an airline or an aircraft maker if circumstances lead to groundings of their fleet. Aircrafts are made to fly, not to sit idle. In fact, it costs money even to keep them on ground. Airlines work endlessly to make maximum use of the fleet they have. But it is no surprise that RA is seen to suffer first, for being slow in making efforts to increase its fleet utilisation and second, in failing to move away B757 it has opted to ground. Both 757s still sit occupying constricted TIA space.
