The backpack is perfect for walking around only. Most airline companies limit their hand luggage to 8 kg or 18 lbs, anyway. Please mind that our telescopes weigh 9 kg and our backpack 2 kg. Moreover, the backpack size (72 x 22.5 x 29 cm) 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, there is a huge 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.

The dimensions of the backpack are: 72 x 22.5 x 29 cm & The tripod's dimensions are: 65 cm x 23 cm

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.
Last but not least, lithium-Ion batteries under 100Wh can be carried in checked baggage as part of portable electronic devices, without any problems.
