My only point in my previous comment was this: for an airline that so many people have preconceived notions about (founded or not), aggressively talking about and taking extreme stances on something as simple as tipping might give mainline guys pause as to whether or not a trip with you would be enjoyable. Personally, I would worry that you would spend all 4 days treating van drivers and wait staff poorly, which would make for unconformable meals and van rides.
