Ryanair seem to have loaded the BOH-PFO flights for S19 as follows:
Tuesdays DEP PFO 13:55 ARR BOH 16:40 // DEP BOH 17:05 ARR PFO 23:50
Saturdays DEP BOH 06:30 ARR PFO 13:15 // DEP PFO 13:40 ARR BOH 16:25
Tuesday uses a Paphos based aircraft, Saturday fills the 'gap' that existed on the BOH based aircraft
