United Airlines will soon introduce a fee for the use of overhead bins for bags in economy. The charge will raise a billion dollars says the airline, which is a member of the Star Alliance to which Air Canada belongs as well. The new rules, which include a new economy ticket, only allows fliers to bring a bag on board that fits under the seat. Any bag larger than that would have to be checked for a fee. The new plan also doesn’t allow passengers to choose their own seats.
