I got the same offer. Too good to pass up. 50k UA points after the first purchase with $65 annual fee waived for the first year. Normal 30k UA bonus wasn't too interesting...I fly CO more than UA, so I'll just transfer the UA points to CO once they post, even though the programs will merge, just to make myself feel better about the marginally higher CO mileage balance

Seems like UA is targeting CO elites (or CO elites who matched to UA) without an existing UA card. I saw the offer on the UA homepage where the 30k offer normally shows up.

I wanted to pull the trigger on chase sapphire 50k offer, but I'm just finishing up the spend requirement on BA chase and didn't want to put any more pressure to spend more money than I have to...I'll apply for the sapphire next month for hopefully another 50k after a few months
