One possibility would be to make seats bigger and give passengers a lot more elbow room — but such a change might feel a bit too “permanent” for the airlines’ taste. In the meantime, Delta Air Lines (NYSE: DAL), at least, has hit upon an interim solution: Since mid-April, Delta has “blocked” reservation of middle seats on all its flights, inserting a space barrier between aisle and window. Beginning today and through at least June 30, Delta will go a step further, blocking reservations of certain window and aisle seats in order to add additional “social distance” between passengers.
