What's the better fleet these days? The general consensus is that the 320 is more comfortable but the 737 has slightly better trips. Are overnight lengths comparable? What about legs per day? Why does the 73N do the majority of the Caribbean/Island overnights instead of the 320? Is there any talk of this changing as more 321 NEOs come on board or will these destinations likely remain with the 73N? Who gets used more on reserve?
