Big reason Bon jovi continue to dominate and sell out every show: Jon's message from tonight's concert in Connecticut which is hammered by a blizzard:

this is what we woke up to this morning. we were concerned for those who were unable to travel to the show and for those who had already traveled a long way to uncasville, ct. postponing the show while still performing tonight for those already here was the best way to address the unavoidable blizzard -jbj

So those who already spent their hard earned money getting a hotel and traveling got a show.. while those who couldn't will also get a show and the people who made it also will get a another show.
