Here is a little tip for those who want to travel across a world but it may be expensive so you may want to do this in custom only.
Do you know how 10 jetpacks can store 100 fuel all at once? Yeah, this will exploit that feature and make it worth saving space on fuel.
For those traveling big worlds if you are owner or admin on a custom world where tps aren’t free, buy a few stacks of jetpacks and travel from there. you will save A LOT of space instead of having to carry around a bunch of fuel.
This may be a useful life hack as it will save a lot of inventory space but may also be expensive if your doing this in vanilla.
