When you talk about insurance, what exactly do you mean?
Are you worried about losing your bag, missing a flight, or falling off a mountain and damaging the scenery?
Insurance is a for-profit business much like a casino. On average, you can expect to always give them more money than you get back. So for any conceivable risk that you can afford to cover, it’s cheaper to not have insurance.
The value of everything in my bag is lower than the amount I haven’t spent on insurance over the years. If I lost it tomorrow and had to replace eveything at my own expense I would still be richer than if I had paid for insurance.
And let’s not forget that there are always exceptions. Expensive electronics may not be covered for example.
Same with flights. I buy the cheapest short-haul, and cheapest convenient long-haul flights (no long waits in airports), none of the insurances. If I have to miss a flight, I eat the cost. It happens rarely enough that there’s no reason to pay the higher fares - and that’s why they offer those fares. They do it to maximise profits.
I’ve been travelling independently for 40 years and never once had a medical issue that required major treatment. If I fall downstair tonight and break my leg then that’s an affordable loss too
But if I fell off a mountain most insurers would turn around and tell me I needed some other kind of specialist policy. A more expensive one.
Most claims are affordable if you budget properly and think of insurance as a gamble. You’re better off without it.
The only time that’s not true is if you have a really really big disaster, one that doesn’t kill you but leaves you with a huge potential bill. How often does that actually happen?
I’m sure everyone has heard a horror story, and someone here may have experienced one, but that doesn’t change the truth: statistically it won’t happen to you, and insurance is all about statistics. Are you going to play the odds or are you going to let them play you?
You can get on a plane between any two points on Earth at a cost a lot lower than the credit limit on your card. If you can survive the journey home you don’t need insurance.
