It appears that the 2A is an "addition" to current sheduled flight plans. Obviously, if they are retrofitting the 2A, they cannot, IMO, have "current scheduled flight plans" for it, which begs the question, which airship(s) have "current scheduled flight plans"?
"The addition of the 2A to TAO's and Sanswire's current scheduled flight plans rounds out GlobeTel's atmospheric arsenal of low to medium to high altitude platforms."
