I was re-visiting this question about a timelapse photo of multiple airliners and started wondering about the maximum number of jetliners that could be photographed together while flying. I have found cases of Airbus aircraft flying in formation for promotional purposes, (see 5 here and 6 here) and I'm sure Boeing have done the same. However I was thinking that a busy airport with a lot of aircraft in holding patterns waiting to land might provide an opportunity for more, even though they would be maintaining vertical separation. Does anyone know of photos like that?
To be a little more precise in what I am asking for, I am looking for a non-edited photo showing the most airliners where the aircraft must be originally built to carry passengers commercially and must be flying (not one of the many reasons photos of planes in "storage" on the ground or stacked up for demolition)
