To illustrate Eddy's point, on 12/10 as an example there are 6 non-stop JFK-SDQ flights on AA.
Also note on October 8th the 9th and the 22nd just to pick a few at random, there are 4 daily flights. 3 on 11/11 however there are still 6 in total with some of these flight stopping in MIA to fill up a bit. So maybe even more MIA SDQ flights.
Please keep in mind santobonao is not what you'd call a paragon of accuracy. Frankly I think he makes most of this stuff up.
