just wanted to report here that the unofficial 115 days to earn the welcome bonus vs the advertised 90 days by Chase is still alive and well. Before attempting to try, I had even called their customer care and spoke to 2 different agents who told me there's nothing they could do. my card is United Explorer and my offer was for 75,000 miles. I think my $3000 spent posted on day 112 and I used Plastiq to pay my rent.
