Security check is always a little stress. Somewhere they let you pass quickly, elsewhere they thoroughly sew you through. What can you do to get through it as quickly as possible?
First, prepare well in advance. Traveling only with hand luggage has many advantages. On the other hand, you need to get everything into it. And this can be a problem with checking. Be sure to leave all forbidden things at home.
First of all, it is important to find out how much luggage weight you are allowed on an aircraft. In Europe it is usually 20 kg + 10 kg handbag, which you can take with you, for long-haul flights, each airline has different transport conditions.
Try using your bike as a sporting item and ask your specific airline to increase the weight limit without increasing the ticket price.
Try to hand the bike as a normal baggage or excess baggage and fit into the weight limits for a free ticket.
