Narrative:

In bos at the time of the occurance; tower was departing to the north and arriving to the west. My route of flight was southeast. I was cleared via VFR route B; which is at or below 1;000 ft. I departed to the north; turned north to east to see the arriving traffic for runway 27. Once I had the aircraft in sight which would be a factor; I was cleared on course. The aircraft on final are advised of my position and that I have them in sight maintaining visual. I passed an arriving passenger airliner rather closely and apparently they had an alert which caused them to go missed. Since the incident; if bos tower is departing to the north and arriving to the west; I depart IFR to avoid a similar incident. Another thing I could do is request from the tower to continue further east before crossing the approach path at 1;000 ft.
