Business class airfare purchases are only permissible with international flight times in excess of five consecutive hours (excluding layovers), however a lower priced economy seat with a seating upgrade may be purchased in lieu of the business class flight as long as the cost does not exceed the business class option quoted at the original purchase.
!Note: An upgraded economy seat instead of a business class seat may be considered an adequate option for an International flight that is more than five consecutive hours. In many cases, the cost of the upgraded economy fare is less expensive than the business class fare that is eligible with an international flight of more than five hours. Comparison quotes should be collected at time of original booking to ensure the upgraded economy fare is less than the most reasonable business class option that meets the business needs of the traveler. A screenshot image of the comparison fares and relevant details should be taken to properly justify the selection.
