All appear to under estimate the A321N & next the A321LR...they are formidable market making aircraft.
The A321LR is aimed precisely at the mid market B757 capability.
Test flights conducted earlier in the year by Airbus equated to (including headwinds) 162 pax over 4,700 miles with 5 crew & 11 engineers aboard,flown in just under 11 hours.
STN-MCO = 4,400 miles in an average flight time of 8.37.
With TCX withdrawing STN-MCO for 2019 it looks as tho PRI can see a opportunity.
