• Premium Economy — A step above economy with more legroom, recline, and service, priced below business class.
• Refundable fare — Cancel at any time before departure for cash back to your original payment method.
• Non-refundable fare — Costs less; cancels for a travel credit rather than cash in most cases.
• Published fare — The price shown on public booking sites and the airline's own website.
• Unpublished or contract fare — A discounted fare airlines give to agencies under contract, not displayed online.
