One thing I learned in my early twenties while traveling a lot is that no matter where you are going, air planes are always going to be cold. There are many reasons to keep the temperature of the cabin of an airplane low, but some people are not used to being that cold. A lot of people who travel frequently know that the AC on the plane is always set to a very low temperature and it can be difficult to remain warm on the plane. Sometimes, I even bring a sweater and a blanket with me when I travel. Depending on the destination and duration of the flight, I always make sure to bring the right kind of clothing depending on where I am going and whether or not the place I am staying has proper heating and cooling. Sometimes, when you get to a place you haven’t been before, you might find that the air conditioner isn’t what you’re used to back home. Also, the heating situation might not be as warm as you are used to. It is better to be prepared when it comes to traveling and packing the right clothing. One time, I went on a trip to a very humid place and found myself sleeping in a cabin with no air conditioner. This really interrupted my sleep and made the first few days of the trip less enjoyable than it would have been if I would have assured that the cabin was equipped with a proper cooling system.
