Ugh. This makes me lose faith in humanity and our collective ability to not jump to conclusions. With the rise in fake news it is now more important than ever before to take a moment and question whether something we read online is written in such a way to generate page views and whether what we're reading is true at all.
In the case of United Airlines recently unveiling a new ticket tier where they would charge you to use overhead bin space, many articles online have just simply jump ahead and started spreading the false news that all overhead baggage will be charged. This is just not true and these numerous articles have spread like wildfire and caused panic in a portion of the public who otherwise would have never even considered buying these lower-priced tickets anyway (and if they do, they know what they're getting themselves into).
So if you're still confused, here's what you need to know: You can still buy United Airlines tickets like you normally would and those tickets will still allow for FREE personal item plus one carry-on item. IF YOU CHOOSE TO BUY A "BASIC ECONOMY" TICKET, which is the new ticket announced by United Airlines, then you are choosing a lower-priced seat at the cost of using an overhead bin. United was hoping the general public would be smart enough to make this choice themselves, but clearly we are all too stupid to figure it out.
