Delta Air Lines is making things sweeter for small and medium-sized businesses to fly with the Atlanta-based carrier. With the expansion of its SkyBonus business travel rewards program, SkyBonus members now have more opportunities to earn and redeem points with Virgin Atlantic. Members can also redeem SkyBonus points with Delta's partner, Korean Air.

The announcement regarding the expansion of the SkyBonus program comes shortly after Delta revealed that Virgin Atlantic and Delta will be boosting the number of flights available between the US and UK for the Summer 2020 travel season.

For the uninitiated, SkyBonus lets business owners turn their company's travel budget into rewards by converting the amount of money their company spends on eligible published airfare and eligible purchased upgrades into SkyBonus points. Enrollment in the SkyBonus program is free of charge though there are a number of criteria a small or medium-sized business must meet before they can join as a SkyBonus member. Currently, there are over 60,000 registered SkyBonus accounts around the world.

At this time, SkyBonus members are not able to earn points when they spend on Korean Air tickets. It is not known whether the accrual of points with Korean Air may be a possibility in the future, considering Delta and Korean Air are joint venture partners. Delta and Virgin Atlantic are joint venture partners, too.

Be that as it may, small and medium-sized companies enrolled in the SkyBonus program can earn and redeem points when they book eligible tickets with Delta, Air France, KLM Royal Dutch Airlines, Alitalia, Aeromexico, and now, Virgin Atlantic.

With the SkyBonus points accrued, companies can redeem them for an array of travel rewards, such as upgrades, flight certificates, Delta Sky Club passes and more. Companies can also choose to redeem SkyBonus points for flights with Delta's partner airlines - Korean Air, Virgin Atlantic, Virgin Australia, Air France, KLM, Alitalia and Aeromexico. To make things even more flexible for participating SkyBonus members, SkyBonus members can use their rewards to cut down on their company's travel expenses, reward their employees or even gift them to their own clients.
