A320 series vs. B737NG series
yeah i know what you guys are thinking... but i really don't want this to develope into the usual Boeing vs Airbus flame war. What i'm after is a comparison of these aircraft performance-wise and in an operational context - effectively answering the question: What makes an operator choose one aircraft series over the other (apart from getting a better deal perhaps) or why did they choose to have both aircraft series in the fleet?!
The reason why i'm asking is that i will have an interview in a few weeks with an airline (low cost / charter Short-/Mediumhaul) operating both aircraft series and i like to present a factual opinion when asked about that matter.
