That is around 150% of the actual price of flying (including coaching). Sadly the tunnel is steeply priced, but the quoted numbers here are around $500 per hour more than reality. 40 minutes per day is also roughly the max what most customers can handle. Flying 90 minutes during 'a morning in the tunnel' is something Id be keen to see.
The skill, precision and progress achieved in an hour of coached flying ($1000 +-) would get you only 20 coached skydives (2 slots) if you are actually getting the coach for free. Seeing most coaches charge around 250$ for a day, you'd be looking at 15 very rushed jumps, if you match that budget of 1000$ with a lot of things not possible to match in skydiving with regards to speed of learning in the tunnel.
Looking at a realistic day in the tunnel being 30 or 40 minutes of flying, you would equal only about 6 or so coached 1on 1 WS skydives on the same budget.
But I would love to jump at the dropzone where Id get 60 x 2 slots for that price and a coach for free.
Nobody is forcing you to go to a WS tunnel, but thinking you get more progression out of 60 solo skydives, is perhaps also a tad too optimistic.
A bit of tunnel and a lot of skydives are a more optimal combination.
Depending on the dropzone you go to, perhaps also not an accurate reflection of reality.
I have no insight in bookings beyond our own, but we're coaching at indoor wingsuit through our own team, only one week a month (8 to 10 camps per year) and so far are always fully booked/sold out, flying around 30 hours of customers per camp.
The views on wingsuit flying as a group of people with no goals in skill or competitive disciplines is something of quite a few years ago, and we're seeing many teams and individuals with a similar drive as often visible in freefly / tunnel who are coming back to the tunnel for multiple visits a year.
As young as the tunnel in Sweden is, just looking at our pool of customers (our = just one of several freelancers) we have a large group of people who are pushing beyond 20 hours of flying, and still learning and eager for more.
It's a steep price, around 900$ for the time without coaching, which I also wish would come down.
But proflyers are a good share of the market. The first time experience there also seems to always be a positive one (not something I/we offer, but we do see a lot of them coming through the tunnel and loving it), so for sure there is a lot of potential there with the right marketing.
Youtube and WS base have created a big monster in terms of interest, which can be used for sure to promote and pull (first timer) customers in...
