August 18, 2025: Sites with affiliate links are reporting that this is the last day for the increased United Quest sign-up bonus.
The United Quest card is still offering a larger bonus, which Chase is touting as the card’s best-ever offer. That checks with the data we’ve collected on this card since its launch.
Here are the best current welcome offers on the United credit cards.

My take: Impressive bonus on the Quest card

United and Chase are touting the Quest card’s offer as the “best-ever” offer, and this checks out with the data I’ve kept on this card’s historical offers. In my view, if you engage with United’s program and redeem miles a few times a year, this is the card to get. Plus, I think that the Quest card got the most positive net changes after United’s early-2025 card refresh.
Either business card can also be a good choice right now. With the welcome offer on either card, you’ll get as many bonus miles as you would get from any previous offer (that I’ve seen) other than the cards’ post-refresh debut offers. And getting PQPs with both offers is a nice perk.
