International flights always allow carry-on luggage, but each airline has its own restrictions as to quantity, size and weight. Some international carry-on policies restrict bag weights to 11 lbs. or less, while domestic flights rarely have a weight limit.

This year, in 2015, the only two big U.S. airline companies that do not charge a baggage fee for checked luggage are JetBlue Airways (first checked in bag free) and Southwest Airlines (which allows you to check in two pieces of luggage for free).ith most airlines charging baggage fees for checked luggage and even some charging a fee for carry-on bags, travelers are forced to spend more and more on their airplane tickets.
