Trivia: I've calculated the sales results very carefully lately... and according to my own point of view (including total capacity of particular venues - not Pollstar/Billboard figures based on random infos from the main distribution services/streams) 36 dates in North America are able to hold even circa 700.000 fans - average capacity reaching number of 19k per gig!!! Huge numbers for classic heavy metal tour in the fever of summer live shows rush in North America. Refering to my calculations of today (11 January 2019) total sales (verify with Mexico too) achieved estimated number of +/- 60 % (36 shows, around 400k fans) of aggregated capacities . Some places are not that bad as many observers suggested so far: (NYC, LA, Montreal, Quebec, Pittsburgh, Calgary, Portland or so) but there're few markets where sales are extremaly poor, e.g..: Nashville, Las Vegas, Mansfield (surprising), Phoenix, New Mexico. I've found all of that weird 'cos so many times in the past Maiden attracted the strong amounts of fans out there. Did they disappointed with band's proposition this time?! I'm expecting nearly to the beggining of the tour, sales'll increase a lot. Expensive tickets for Maiden and the other legendary acts tours (Ozzy, KISS or so) couldn't help to accelerate the final results up... So, most of the rock/metal fans even in America have to calculate and decide which concert ticket they should buy first. Finally I decided not to check the current sales results on seating maps until the second week of forthcoming April 2019. I've found this period as reliable to estimating anticipated progressing or just stopping the sales results. I'm expecting to find many seats unavailable after the three next months of spare time. I finally can't believe the most of American fans just turned their backs on the Irons!
