I asked a simple question, got a simple answer, then replied with a simple thought about why they'd have to get retrained. More exits would mean they'd technically have to get retrained for different briefing and possible evac procedures. I don't really know of anything else different with the aircraft since it seems rather identical. There was nothing sarcastic about it at all. Must you think everyone is so cynical? I try to keep the sarcasm to a minimum and it's usually accompanied with a or or Just FYI.
