<p data-start="1086" data-end="1855">One of the most attractive features of the Air Transat Upgrade program is its variety. Passengers can choose to bid for an upgrade through the airline&rsquo;s Option Plus or Club Class systems, pay directly for an upgrade before departure, or occasionally receive upgrade offers at check-in or the boarding gate. Club Class is the ultimate upgrade experience, providing business-class style seating with wider, more comfortable chairs, extra legroom, and priority services. Option Plus, on the other hand, gives economy passengers added benefits such as priority check-in, free seat selection, extra baggage allowance, and special onboard amenities. These flexible choices make upgrading accessible to a wide range of travelers, depending on their budget and preferences.
