This is what their website says regarding retro-credit anyways. Could just be an unrelated outage/upgrade they're doing to mileage crediting processes that just happened to cross 2/29.


I will say it looks like they overhauled their entire MPSC page recently https://www.united.com/en/us/fly/mil...ce-center.html . Makes me think they're doing some type of upgrades to some MPSC related systems/pages and its unrelated to it specifically being 2/29. After all they're still processing redemptions (and have a leap day promo).
