Dont see Ryan Air EasyJet rushing out to buy turboprops.
737 or A319 can operate 12 sectors a day carry up to 1200 pax
with 2 operating crews.
Turboprops are realy good on the odd specialised routes.
Tuboprops are complicated, they vibrate, they do not fly high enough or fast enough, they suffer from icing problems.
To get Turboprops to vibrate less like the Q400 makes them even more complicated.
They cost nearly as much to manufacture as jet aircraft and especially in Europe are only economical, when virtualy given away by desperate manufacturers who cannot sell aircraft .
Or when old and suitable for freight , which could not care less.
As to what aircraft pax prefer.
No contest
Jet aircraft.
Pax think , Dambusters when they see props.
