and the group I was hiking with started feeling it a little bit around 9000-10,000 ft.

Hiking. Physical activity. You'll feel it a lot sooner than if you're just sitting in your seat, bored out of your skull.

Legally, the FAA doesn't require passengers to be on oxygen until cabin altitude is above 15,000 feet. Most aircraft are pressurized to the equivalent of 5000-7000 feet pressure altitude.
