Not everyone is privileged and has the means to afford airline travel. There are lots of people who save up for months just to pay for airline tickets to their dream destinations. They get on the plane and sit on one of the seats in the economy class, excited and amazed at everything going on. They are offered blankets that are neatly folded and packaged, and they take it.
What these passengers don’t know is that they are entertaining the possibilities of getting sick in using those blankets. Over the internet, people are sharing their in-flight experiences regarding their observations on the care and maintenance of those blankets. Most of the time, passengers are given blankets that have not been washed and were simply refolded and rewrapped. This opens doors for health problems, especially if the person previously using the blanket happens to be sick.
