Q300/q400
Sorry but without going into your numbers the ATR blows away the Q's for all segments under 300 nm. Period - I do not have to spout my figures. Secondly, the q3/q4's are not interchangable cockpit/engines/equipment etc. This is good old fast plane but who needs it? It works in europe and the USA as people are willing to pay for the longer and thinner routes but not in Asia. So bring em on - 100% 5J will continue to be number one until the cows come home. Ask PAL's key people there (the smart ones) wanted the ATR but were over rulled (hm nothing to do with the lear jet ha?).
Only time will tell ------------
