I maintain four daily is daft if you can get them all on three bigger aircraft
The B757 is in it's twilight years so I would imagine ORD B772, PHL A333 plus a.n.other, I would suspect B763 on JFK would be the way forward. Looks like a capacity gap if they're already full so early. Let's wait and see, I still want to shoot some of the B757s before they all go with the seagull trapped in letterbox livery. (I actually like it a lot)
