In most US Airlines, one personal item is free, and one carry-on item is free in the airline's baggage policy. Thus, you don't need to pay the baggage fee for these two items. It is the best thing for the people who want to manage the journey without paying enough baggage fees. The US Based Airline Info is available on both third parties and the official airline site as well. For example, if you want to book Delta Flights for International travel and as we know, delta is the major airline of the United States, then we can say that it is the major US Airline for the holiday goals of the passengers. Thus, you can reach the delta airlines official site to know more about this airline or also explore the search bar on Wikipedia.
