The backpack is perfect for walking around only. Most airline companies limit hand luggage to 8 kg or 18 lbs, anyway. Please remember that our telescopes weigh 9 kg/ 19.84 lbs and our backpack 2 kg/ 4.41 lbs. Moreover, the backpack size (72 x 22.5 x 29 cm or 28.35 x 8.86 x 11.42 inches) does not fit the hand luggage requirements; it's slightly longer.
Now, we do not recommend putting your telescope simply in the backpack in checked luggage on an airplane/flight, as there is a considerable chance it might be damaged. Our team uses rigid cases while traveling to make sure that their telescopes are perfectly safe. Below, you will find a few tips on hard/rigid cases.

Some team members used The Pelican 1650 or The Pelican 1615. The Pelican 1650 - for this case, use the white foam that comes with the packaging of your UNISTELLAR telescope and insert it inside the case - it fits like a glove, as you can see in the image below:
The Pelican 1615—For this smaller case, you can simply shape the foam to fit the telescope/toolbox/tripod.
Another option would be using a Nanuk 962 case:
Last but not least, lithium-ion batteries under 100Wh can be carried in checked baggage as part of portable electronic devices, without any problems.
