While it is both nice and proper that UA instituted these upgrade features for UGS and 1K customers, all of who have multiple forms of paper certs to upgrade transcon and international itineraries for both themselves and others (time to start ingratiating myself with some 1Ks for my LHR and SIN trips ), it would have been nice if they had also allowed 1Ps and 2Ps (and UGS and 1Ks) to be able to request mileage upgrades, as well. We still have to call the desk for those, but at least UA is nice enough not to charge us $5 or $10 for the privellege, so we shouldn't be too bitter.
