Swych has two offers for new users only:

• $100 Southwest gift card for $90 (code triptime19)
• $25 Uber gift card for $20 (code rushhour19)

Not the best deals but if you have a use for these brands, then could be worth singing up. Keep in mind that you can no longer earn 5X at Swych, so just use a card that earns at least 2%.
