The internet keeps telling you that indoor skydiving is “just like real skydiving without the plane.” It isn’t. Not really. They share one physical principle and almost nothing else.
I’ve done both. Here’s the honest side-by-side, the things the marketing gets wrong, and — if you can only afford one — which one to book first.

The core misunderstanding
People assume indoor skydiving is a simulator for real skydiving in the same way that a flight simulator is for flying a plane. That framing is wrong, and it leads to bad decisions.
A flight simulator is trying to replicate the cockpit environment, the controls, the decision-making, and the physics of flight. It’s a training tool for pilots.
Indoor skydiving is not trying to replicate a skydive. It’s trying to let you practice one specific component of a skydive — body control in falling air — in a safe, controlled environment. Real skydivers use tunnels (iFly included) as training tools for exactly that component.
For a first-timer, the two experiences are genuinely different products. They share the physics, and nothing else about them is the same: the cost isn’t, the duration isn’t, the fear profile isn’t, the preparation isn’t, and what you walk away with isn’t.
The eight-axis comparison
Let’s compare on the axes that actually matter.
1. Cost
- iFly (first-time, all-in): $70 list price, $100-$130 realistic with photo/video package and high-flight upgrade.
- Tandem real skydive: $250-$350 for a single jump, with video package often another $100-$150 on top.
Real skydiving is roughly 3x more expensive per session. This matters more if you’re budget-constrained, and less if you’re asking “what gives me the most memorable single experience.”
Winner on cost: iFly, decisively.
2. Duration of actual flight
- iFly: Two 60-second flights = 120 seconds of actual flight time.
- Tandem skydive: Roughly 60 seconds of freefall, followed by 5-7 minutes of parachute descent back to the ground.
This is where the comparison gets interesting. iFly gives you more freefall-equivalent time than a tandem skydive. The tandem gives you a longer overall experience (the ride up, the plane ride, the descent under canopy, the landing), but only about a minute of it is the falling part.
Winner on flight time: iFly gives you more minutes of the thing you came for.
3. Adrenaline and fear
This is where real skydiving wins decisively, and it’s not close.
In the tunnel, you stand on a mesh floor and lean into moving air. There is no fall. There are no stakes in the primal, animal-brain sense. The part of your nervous system that screams “don’t jump” is never activated because you don’t jump.
In real skydiving, you sit in the open door of an airplane at 12,000-14,000 feet, with your instructor strapped to your back, and you push yourself out. The body’s fear response is not negotiable at that altitude. It activates whether you want it to or not. Your heart rate goes to 180+, your perception of time slows, your hands shake, and then you’re in freefall at 120 mph and your brain has to rewire on the spot.
The entire experience of the first tandem jump — the plane ride up, the door opening, the jump, the freefall, the chute opening, the descent, the landing — is the closest most people come to genuine primal fear as an adult. It is not comparable to indoor skydiving on this axis.
Winner on adrenaline: Real skydiving, by a factor of 10.
4. Safety
Both are significantly safer than their reputations suggest. Modern tandem skydiving has a fatality rate of roughly 0.2-0.3 per 100,000 jumps in the US, which is lower than the per-mile fatality rate of motorcycle riding by a large margin. Indoor skydiving’s serious-injury rate is even lower — the main risks are sprains and tunnel-wall collisions, essentially gym-injury level.
That said, they’re not the same category of risk:
- iFly risks: Minor sprains, shoulder strain, goggle or helmet discomfort, occasional vertigo. Nothing that lands people in hospital often.
- Tandem skydiving risks: Parachute failure (very rare, and the instructor has a reserve), hard landings, medical events at altitude. The floor on the bad outcomes is much lower, even if the probability is also low.
Winner on safety: iFly, for people with any cardiovascular concerns especially.
5. Learning curve and skill transfer
This is where iFly’s real value becomes clear.
At iFly, you are actively learning a skill. Your instructor coaches your body position in real time. You can see yourself improving between flight one and flight two. You leave with a slightly better understanding of how your body interacts with air. That understanding is cumulative across sessions — people who buy 10-flight packages get meaningfully better at body control.
In a tandem skydive, you are a passenger. Your instructor does almost all the work. You are told to arch your back on exit, and that’s the extent of your active participation. You learn almost nothing about body flight from a tandem jump. You have an experience, but not a skill.
If your goal is to eventually become a licensed skydiver, iFly is where you learn. Every serious skydiver in the US has spent time in tunnels. The tunnel is the training ground; the sky is the performance venue.
Winner on skill transfer: iFly, completely.
6. The story
This is where real skydiving wins again, but differently.
“I did indoor skydiving” is a story. It’s a good story. People are interested.
“I jumped out of a plane” is a bigger story. It commands more attention. It’s the kind of story that becomes part of how people identify you — “oh, Alex, yeah, Alex did skydiving that one time in Arizona.” The experience stays with you and with your social network in a way that indoor skydiving does not.
This isn’t a trivial consideration. A lot of people book real skydiving specifically because they want the story, the Facebook post, the “I did it” moment. iFly doesn’t produce that same social signaling value.
Winner on story: Real skydiving, clearly.
7. Who can participate
iFly’s participant range is almost unlimited:
- Ages 3-103 have all flown
- Almost no fitness requirement
- Prescription glasses, contact lenses — fine
- Small weight restrictions (typically up to ~260 lbs)
- Minor medical conditions usually OK with waiver
Real tandem skydiving has more restrictions:
- Minimum age typically 18 (some drop zones do 16+ with parental consent)
- Weight limit typically 220-240 lbs (strict, enforced at the dropzone)
- Heart conditions, uncontrolled high blood pressure, recent surgery, pregnancy — all excluded
- Must be reasonably ambulatory
- Insurance and waiver requirements are much more involved
If you are considering this for an older parent, a younger child, or someone with health restrictions — iFly is the only option.
Winner on accessibility: iFly, by a huge margin.
8. Weather dependency
- iFly: Indoor. Weather doesn’t matter. Your booking happens on schedule.
- Tandem skydiving: Weather-dependent. Rain cancels jumps. High winds cancel jumps. Poor visibility cancels jumps. Even moderate conditions can push your booking by hours or days.
This sounds minor until you’ve driven two hours to a drop zone, sat in the lobby for four hours, and driven home without jumping. I’ve had it happen. Friends have had it happen twice in a row with the same drop zone. It’s a real factor, especially if you’re booking around travel.
Winner on reliability: iFly, significantly.
Which to book first
If you’ve never done either, my strong recommendation: book iFly first.
Three reasons:
One, it de-risks the real jump. For $70, you learn whether you actually enjoy the sensation of fast-moving air on your body. That’s the core physical component of skydiving. If you hate it at iFly, you’d hate it from an airplane, and you just saved yourself $300 and a lot of anxiety. If you love it at iFly, you now know to book the tandem jump with excitement instead of anxiety.
Two, it’s a better education. You learn the body position. You learn what hand signals mean. You learn what the wind feels like on your face. When you do eventually jump out of an airplane, you’re a participant rather than pure cargo, because you’ve practiced the physical motions before.
Three, it’s cheaper as a sampler. If iFly gets you hooked and you want to do real skydiving after, you spent $70 + $300 = $370 total. If you book real skydiving first and you love it, great. If you book real skydiving first and you hate the sensation, you spent $300 to find that out. The iFly-first sequence has a better expected value.
The one exception: if your entire motivation is the story — the Facebook post, the “I did it” moment — skip iFly and book the tandem. iFly won’t give you the story you’re actually buying.
When iFly is a complete substitute for real skydiving
For some people, iFly is not a stepping stone — it’s the destination. These are:
- People with medical restrictions that rule out the tandem jump (heart conditions, weight limits, age).
- People who want the flying sensation without any risk tolerance for the small-probability-but-nonzero bad outcomes of a tandem jump.
- Parents who want the experience for their kids under 18.
- People who go to iFly repeatedly and treat it as a hobby — you can get genuinely good at body flight in a way that a handful of tandem jumps will never teach you.
For these groups, iFly is the answer. Real skydiving isn’t a better version of iFly for them; it’s a different activity with different requirements.
When real skydiving is a complete substitute for iFly
Less often, but real: if you know you want to jump out of a plane, you have the budget, you have no medical restrictions, and you want the story — there’s no reason to do iFly first. Book the tandem. Have the experience. The tunnel won’t add much.
This is mostly people in their 20s on bucket-list trips, military veterans, and people who’ve been putting it off for a decade and finally want to just do the thing.
The verdict
Both are legitimate experiences. Neither is a knockoff of the other. They answer different questions:
- iFly answers: “What does my body do in fast-moving air, and is that a sensation I enjoy?”
- Real skydiving answers: “What is it like to overcome primal fear and commit to something my animal brain is screaming not to do?”
Different questions. Different products. Different prices. The mistake is thinking one is a substitute for the other.
For the average curious person with a $100 budget: book iFly. It’s a better use of $100 than a tandem sampler. If you end up wanting the sky, you’ll have saved the jump for when you can properly commit to it.
For the person who has $300-$500 to spend and wants the biggest single adventure experience of their year: book the tandem. Buy the video package. Don’t skip the story.
For the person who has $400+ and wants both: book iFly first, book the tandem second. The iFly session prepares you for the tandem in small but real ways, and you get two different stories.
Bottom line: iFly and real skydiving are different products, not different versions of same product. iFly wins on cost, skill transfer, accessibility, and reliability. Real skydiving wins on adrenaline and story. Book iFly first if you have a $100 budget and are curious. Book a tandem if you have $300 and want the story. If you can afford both, do iFly first — you’ll get more out of the tandem because of it.
