Upgrade vouchers

Upgrade vouchers are special certificates or codes that airline or travel companies offer to customers, allowing them to move from their booked standard class to a higher class of service—like upgrading from economy to business—without paying the full fare difference. They are often provided as perks for frequent travelers, loyalty program members, or as part of promotional offers. When used, these vouchers help enhance the travel experience by providing more comfort and amenities, making it a cost-effective way to enjoy a more premium journey.
