Price, flight times, and minimal number of connections are the main focus; but is there a website that can add in aircraft type?
I realise types can be swapped, but with historical data there should be very high probability of prediction of aircraft type at booking.
I flew a 757 back in the 1980s and have fond memories of it. This article made me realise that a spate of flying in 737s might have been what put me off flying for so long.
