Travel to a destination generally involves being in a cramped space for many hours. Most likely you will be sitting for hours. Therefore, when you arrive you need to get the blood flowing and get your mind back into reality. When I design a post-travel workout, I want it to increase the circulation of blood and cause a good sweat to help with post-travel effects. The workout will not be high intensity because flying usually involves dehydration and will mean you will be stiff from sitting. The cool down should be 20-30min easy walk to really help promote recovery.
Generally, I will also throw in dynamic and static stretches to help with tightness. When I travel, I always tell people to bring a foam roller and spend plenty of time rolling out the tight areas.
Here is a favorite post-travel workout:
