Basically it is a lottery, you might be satisfied or, like me, hugely disappointed.
In my case, they put 6 people on board, 1 in front and 4 next to windows, while I as assigned the seat in the middle with an obstructed view.
I paid exactly the same amount of money, as everyone else, 229 USD.
People sitting next to the windows were taking photos and/or filming, which I completely understand because it is the very reason to go for the ride. I just took few photos, and every time I had to excuse someone to do it.
I complained about the assignment of the seat soon after the flight. The staff was very unpleasant, and said that it was the company policy (!?), and I should contact my tour organizer, as if the tour company had anything to do with the flight.
They offered me a 20 USD discount at first, then after my complain emails - 50 USD, which I did not accept. I wanted at least 50% return of the money. I was hugely disappointed and irritated, they ruined my trip, for which I waited many, many years.
They also offered me another flight, but I was with a group, which could not wait for me. And besides, why couldn't they do it right from the beginning! So annoying.
The company does not warn that the view might be obstructed; quite the opposite, they advertise the flight for its views! Check the homepage.
The second explanation was that the helicopter had to be balanced... which is a complete nonsense. The helicopter can balanced with any number of people.
They put 6 people instead of 5 people on board to increase the profit.
Besides, the aircraft is old and noisy, even with the headphones. I could not hear the narration that is played during the flight.
Very, very disappointing and irritating experience.
My advise, get another company.

We offer our apologies that the allocated seating left you dissatisfied. Seating is allocated by the weight and balance calculations of the aircraft; this is an industry standard of safety as small aircraft must be properly balanced in order to fly safely. There are times that the aircraft must be flown with fewer number of people - again, this is for safety reasons and not for profit. We also offer front seat upgrades as an option to our passengers. Most guests find our seating comfortable with good views as we only fly helicopters designed specifically for sightseeing. We regret that our offers of compensation and an additional tour were not acceptable, and we do hope you enjoyed the rest of your visit to Las Vegas.
Respectfully,
Papillon Management
