Avoiding An Awkward Situation
You can do away with checked baggage but almost never with carry-on luggage. These days most airlines are advising passengers to limit their baggage on a single carry-on bag.
It will not only save them time in the airport, it will also dramatically reduce risks of losing a luggage. However, due to security issues, you can’t bring anything that strikes your fancy. You want to know what is allowed and what is prohibited. It’ll help you move along on your trip smoothly and avoid a possible trip to the airport’s interrogation room.
