Overweight and oversized bags will incur additional fees, which can be substantial. Checked bags weighing over 40 pounds will cost more, and anything over 100 pounds or 80 linear inches is not accepted.Another key part of the is the optional “Bundle It” combo, which offers value by including a carry-on, checked bag, seat selection, and other perks at a discounted rate.
