You just answered your own question. Imagine what it must cost Maiden to fly 70 crew to your city, not to mention all the other expenses. Obviously, there must be the potential for Maiden to loose $ in your city, so the promoters in your city aren't going to pony up big $ from their own wallets and risk not getting it all back. And no promoter is going to take on that much work just to break even.
False. If all the shows they do they fly to, it would make no sense to skip a city based on travel expense. It would cost relatively the same to fly into Atlanta as it would to fly into Chicago/LA/NY. I don't see any other expense being so economically grand that to skip an entire region wouldn't make financial sense.
The point is, the show would sell out. No matter the capacity of the arena, and probably no matter the ticket price...if it's pretty evenly matched with the rest of the dates. I would pay 120 bucks for the show, if I could make the show within a reasonably short drive and then drive home that same night.
It's a completely different monster to have to buy the ticket, buy a plane ticket, arrange for a hotel, drive, sleep, go to the show, sleep, and then go home. That's 3 days as opposed to one day and a long night. Fuck that. It's different, and you know it.
And to address DTJeff, I agree with you on the Maiden setlist point in theory, but I have yet to be able to comfortably see Maiden on ANY tour. That's the crux of this topic. Your point is that "Maiden tours enough...you'll hear those songs...eventually." NO I WON'T!
