I’ve been EXP this year for the first time since 2016. Back then EXP was really worth it… I almost always got upgraded. This year, I was almost hardly ever upgraded. Over the past year I’ve actually flown MORE but have had much less spend on my CC (we moved last year).. because of that I’m gonna end up about 40,000 LPS short( which I find hilarious). In another day and time I’d do whatever I could to get to EXP to get the SWUs… but aside from a really lucky upgrade on HNL-OGG I’ve never been able to use them. In short… IMO unless you’re really close, EXP isn’t really worth it.
